SAFETY PRECAUTIONS
Your photographic equipment is powered by mains electricity,
and is designed to comply with international electrical safety
standards. However, basic safety precautions must always be
followed when operating electrical equipment, including the
following, where applicable:
Read and understand all instructions.
Observe labels on the equipment, particularly those advising of
possible hazards.
Close supervision is necessary when the equipment is being used
by inexperienced personnel.
Take care to avoid burns. Some internal parts of the equipment
can become very hot with continuous use.
Do not operate equipment that has been dropped or damaged,
or has damaged electrical leads. Have the equipment examined
by qualified personnel.
Do not allow any electrical lead to touch hot surfaces.
To comply with safety and EMC requirements, ensure that the
mains socket provides a proper connection to earth.
Ensure the leads are arranged such that they cannot be pulled or
tripped over.
Ensure the air flow through the vents is not obstructed when
operating the equipment. An obstructed air vent can lead to
overheating.
Do not dismantle the equipment unless you are qualified to do
so. Incorrect assembly can cause hazards both to yourself and to
the equipment.
Always obey local codes of practice, particularly for installation
requirements.
Do not destroy these instructions

DESCRIPTION
2.1
2.1a
6
The MULTIGRADE 600 system is easy to install and straightforward
to use. By following the instructions in this manual, quality prints,
together with continuous and reliable operation, are assured.
MULTIGRADE 600H ENLARGER HEAD
See figure 2.1.
The MULTIGRADE 600H diffuser enlarger head replaces the
original condenser, diffuser or cold cathode lamphouse used with
a range of professional enlargers. It is fitted to the enlarger
chassis using an adaptor kit, designed to make installation quick
and relatively simple.
Light source
The enlarger head is fitted with a fan cooled high output halogen
lamp, heat filter and motorized yellow and magenta dichroic
colour filters.
The lamp is kept running at low power (pre-warmed) whenever the
system is switched on, to provide quick start-up and consistent results.
The cooling fan runs only while an exposure is being made.
Extremely stable and repeatable exposures are provided by a
proven closed loop light monitoring system and motorised light
shutter mounted in the base of the head, just above the light
mixing box. Light from the filters is reflected and diffused in the
mixing box to provide even illumination of the negative. The
colour variation obtainable enables the wide contrast range,
available with ILFORD variable contrast papers, to be used to its
full advantage.

Note
A single servo motor drives both filter carriers. At one extreme,
the magenta filter is fully in the light beam (Grade 5). At mid-
travel, both filters are clear of the light beam and white light is
transmitted (at Grade 2.5) giving maximum printing speed. At
the other extreme, the yellow filter is fully in the light beam
(Grade 00). The yellow and magenta filters can never both be in
the light beam at the same time.
Light mixing boxes
A range of light mixing boxes is available, including sizes
35mm, 6x6cm, 6x7cm, 6x9cm and 5x4inches.
The box or boxes required are not included with the MG600
system and must be ordered separately. Additional boxes may
be ordered at any time to suit user requirements.
To fit the light mixing box, see section 4.1a.
MULTIGRADE 600C CONTROL UNIT
See figure 2.2.
The MULTIGRADE 600C control unit is quick and simple to
operate. Once the exposure time and contrast are established,
the permanent microprocessor controlled closed loop system
checks light intensity and colour before each exposure. A
correction is made automatically to the exposure time and
filtration (if required) to ensure consistent print results time after
time.

The control unit provides five paper channels. Four are pre-
programmed for ILFORD papers (see section 2.7) and one is left
free for programming by the user, if required.
Note
All channels can be checked and/or re-programmed (see section 8).
The control unit also incorporates calibration facilities to ensure
that the desired print density and grade are obtained when
scanning an image with the probe (see section 8 ).
All controls are described in section 3.
For maximum operator safety, the control unit is powered entirely
by low voltages supplied from a remote power supply (see
section 2.3).
The brightness of the display and button indicator lights
optimised to be seen under normal darkroom lighting. During
normal use, the displays will not fog ILFORD variable contrast
papers or other black and white paper of similar sensitivity.
MULTIGRADE 600S POWER SUPPLY
See figure 2.3.
The MULTIGRADE 600S stabilised power supply is connected
directly to the electrical mains supply. It has sockets for
connecting the enlarger head, control unit and footswitch or roll
easel, positioned on the rear of the unit. The on/off switch,
showing ‘O’ in the off position, controls power to the system.

CAUTION
The unit is factory set to mains voltage of 230V. Before switching
on the unit please check the correct mains voltage is selected and
the correct fuse is fitted, see section 4.2a.
MULTIGRADE 600P EXPOSURE PROBE
See figure 2.4.
The MULTIGRADE 600P probe saves paper and time by
eliminating the need to make test strips or sheets.
The brightest and darkest parts of the image are scanned and the
readings obtained enable exposure time and grade to be
automatically calculated and displayed.
For a detailed description of how to use the probe, see section 7.
MULTIGRADE 600F FOOTSWITCH
The MULTIGRADE 600F footswitch is available as an optional
extra, and enables the printer to keep both hands free. The
function of the footswitch is to start an exposure only. If an
exposure in progress is required to be cancelled, this must be
done on the control unit.

AUTOMATIC ROLL EASEL
The MULTIGRADE 600 system can be connected to most
automatic roll easels. Connection is made via an 8-pin Siemens
plug (as typically used on Durst roll easels). Please contact
ILFORD for inter-connection details.
PHOTOGRAPHIC PAPERS
The MULTIGRADE 600 system is designed for use with ILFORD
MULTIGRADE variable contrast papers.
MULTIGRADE paper
The control unit is pre-programmed for the following papers:
P1 ILFORD MULTIGRADE IV RC Deluxe
P2 ILFORD MULTIGRADE RC Warmtone
P3 ILFORD MULTIGRADE IV FB Fiber
P4 ILFORD MULTIGRADE FB Warmtone
P5 Spare channel
Other papers
Colour prints or prints from graded papers such as ILFORD
ILFOSPEED can be made using an appropriate setting from one
of the paper channels (grade 2.5) where both yellow and
magenta filtration values are set to zero, ie the enlarger head is
projecting white light. See section 12.
Alternatively, if it has not been reprogrammed, any grade setting
in paper channel 5 (P5) may be used.
During use, the control unit will display the grade set but this will
have no relevance to the prints being made.

CONTROLS
3.1
3.2
11
See figure 3.1.
All controls necessary to operate the MULTIGRADE 600 system
are located on the control unit, except for the power control
switch which is located on the power supply.
CONTRAST SELECTION
Grade is displayed in the centre display and is set by holding
down the ‘Grade’ button and depressing the +/– buttons to
increase or decrease the set value. The buttons control grade
selection from 5 (highest grade) to 0.0 (low grade) in 1/10
grade steps. At setting 0.0, a further press of the – button selects
the lowest grade 00. Holding the +/– buttons down causes the
display to roll sequentially in increments of 1/10 grade.
Note
When making changes to the grade setting, any necessary
changes to the exposure time to maintain a constant print density
will be automatically set by the control unit.
ELECTRONIC TIMER
Exposure time is displayed in the right hand display. Time is
displayed in hundredths of a second for 1.00 to 9.99 seconds,
tenths of seconds for 10.0 to 99.9 seconds and in whole
seconds from 100 to 999 seconds. The display counts down to
zero during main exposures, then resets to the set value.
The required exposure time is set using the +/– buttons. A short
press will increment the set value. Keeping a button depressed
will cause the time to roll up or down. The roll rate increases if
the button is held depressed for more than two seconds.

Note
The exposure time cannot be incremented in less than 2% steps.
Exposure time may also be adjusted using the ‘% Time’ button.
When the ‘% Time’ button is depressed, the time display shows
zero. Whilst holding this button depressed, the required
percentage time adjustment can be set using the +/– buttons. On
release of the ‘% Time’ button, the corrected time is displayed.
The operating range of % Time is –99% to +999%.
Note
When an exposure is initiated, the closed loop control system
assesses colour and brightness of the exposing light before the
shutter is opened to begin the exposure. Any necessary
corrections to maintain a constant exposure are made
automatically and this could result in the set exposure time
changing to a different value, from which the countdown then
begins.
This is normal operation for the system. The effect will become
more pronounced (an increase in exposure time) as the lamp
ages and its light output reduces, or the colour filters become
dirty, etc.
EXPOSE
With the time and grade selected, start the main exposure by
pressing the ‘expose’ button. The time will count down to zero.
Exposure can be stopped at any time by pressing the ‘expose’
button. Pressing the expose button again will re-start and
complete the remaining exposure. If the remaining exposure is
not required, pressing the ‘clear’ button resets the timer to the
original exposure time.
FOCUS
To obtain a continuous light suitable for focusing and
composition, press the ‘Focus’ button. To cancel the ‘Focus’
mode, press the ‘Focus’ button again (or the ‘Clear’ or ‘Expose’
buttons).
PRINTS COUNTER
The control unit automatically counts the number of main
exposures (additional burn-in exposures are not counted). This is
particularly useful if a run of identical prints is made from one
negative. To obtain the display, simultaneously press the ‘Focus’
and ‘Burn’ buttons. For example, 99 exposure cycles is displayed

Notes
The prints counter will also record a cancelled exposure cycle.
The print counter retains the count value when power to the unit
is switched off. Ensure that the counter is zeroed before starting a
new print run.
PAPER CHANNEL SELECTION
The ‘Paper’ button is used to select paper channels P1 to P5 (see
section 2.7). The selection is indicated in the left-hand display.
MANUAL BURNING-IN
The ‘Burn’ button selects a continuous exposure at the grade
shown on the display for manual burning in. If required, the
grade can be changed during the exposure.
To cancel the ‘Burn’ mode, press the ‘Burn’ button again (or the
‘Clear’ or ‘Expose’ buttons).
BURNING-IN OPERATIONS USING THE MEMORY
FACILITY
The control unit incorporates a memory store, capable of storing
a maximum of three exposures in addition to the main exposure
and is selected using the ‘Memory’ button. The memory store is
particularly useful for programming a sequence of additional
exposures to follow the main exposure. Each additional exposure
can be made at a different grade. Once the memory has been
programmed, the control unit steps through the sequence of
exposures each time the ‘Expose’ button is pressed.
See section 6.
Note
The stored memories are retained when the equipment is
switched off.

exposure 1E, to be followed by burn-in exposures 2E, 3E and
4E.
Press ‘memory’ again and ‘2E’ will appear in the memory
display. As a start point, this second exposure always sets to
50% of the main exposure (at the grade setting previously left in
the memory).
Reset the exposure time and grade to the settings required for the
second exposure (first burn-in memory).
Press ‘memory’ again to select the third exposure. The last grade
value used will appear in the display. An exposure time may
appear if it was not previously cleared.
Set the exposure time and grade to the settings required for the
third exposure.
Repeat 5 and 6 to set the fourth exposure if required. If not
required, cancel the exposure time by pressing ‘Clear’.
Note
The control unit will ignore exposures 3E and 4E when the
exposure time is set to ‘– – –’.
A further press of the ‘memory’ button will return the control unit
to normal mode, where only this exposure will be activated on
pressing ‘Expose’.
To use the burn-in memories set as above, again press ‘memory’
so that 1E is shown in the display.

Notes
The burn-in memories are retained in the memory unless
cancelled or reset.
The exposure time of memory 2E cannot be set to ‘– – –’. If only
the main exposure is required, set the control unit back to normal
mode with a paper channel showing in the display.
If the main exposure time is reset (when either set to a paper
channel or to ‘1E’) then the times set in all memories will be reset
in the same ratio. The grade settings are unaffected.
If any recalculated exposure time is less than 1.0 seconds, the
value will be displayed but will flash indicating that this exposure
cannot be made.
Pressing ‘% Time’ when the display is showing memories 2E, 3E
or 4E indicates the burn-in exposure as a percentage of the main
exposure 1E.

Insert the negative to be printed into the enlarger. Select ‘Focus’. Focus
and compose the required image and set the working aperture (f-stop)
of the lens.
Select the appropriate paper channel on the control unit.
Check the probe LED is switched on. Position the probe photocell in the
brightest area of the projected image and press and hold the probe
button.
Note
The probe button must be held down during the complete measurement
cycle.
When the probe LED extinguishes move the probe measuring cell over the
brightest and darkest areas of the image. Release the probe button.
The calculated exposure time and grade is then displayed. Unless you
wish to make a further measurement, cancel the focus light and prepare
to make a print.
Position a sheet of paper on the enlarger baseboard. Press ‘expose’. The
sheet is given the calculated exposure. Process and assess the final print.
The exposure probe can be used if the control unit has stored memories.
Note
The exposure times set in the burn-in memories will be modified in the
same ratio as the new and previous main exposure times. The grades
set in the memories are unaffected (see section 6 Note c).

USING THE EXPOSURE-CONTRAST PROBE
SOME NOTES AND GUIDELINES
If used correctly, the MULTIGRADE 600P exposure probe can be of
great benefit to the black and white printer. Listed below are some
simple rules to observe in order to maximise the probe accuracy.
Pressing the probe button opens a shutter covering the measuring
cell and begins the measuring cycle.
During scanning, the probe takes ten readings per second. The
highest and lowest readings are stored and enable the grade and
exposure time to be calculated.
Also during scanning, the display shows the previously set grade
and a number which represents the density being measured by the
probe. This enables the lightest and darkest areas of the image to
be found (if necessary). The difference between the highest and
lowest numbers represents the contrast of the negative.
If the light level measured is too low, the display will show Pr bd HI
(Probe density high). The lens aperture should be increased and a
new probe measurement taken.
If the light level is too high, the display will show Pr bd LO (Probe
density low). The lens aperture should be reduced and a new probe
measurement taken.
The probe is not affected by normal levels of darkroom safelighting.
However a very bright safelight situated close to and above the
enlarger baseboard could have an effect. This can easily be checked.
Operate the probe button to initiate a probe measurement. View
the density value being displayed on the control unit (see 7.1 para
3 above) and switch the local safelight on and off. If the number
displayed is affected, then for accurate results, this safelight should
be re-sited or switched off when using the probe.
If the paper channel is changed, the image must be measured
again for accurate results.
Obtaining good results with the probe requires some familiarisation with
its use. It is not necessarily the absolute brightest and darkest parts of the
image which should be scanned, but rather the areas in which detail still
needs to be seen in the resulting print. Extreme dark areas or highlights
should therefore be avoided when scanning.
The MULTIGRADE 600 system is programmed to calculate the correct
exposure time for a wide range of negatives. Inevitably, there will be some
negatives (showing extremes of exposure or development or not having a
suitable area from which to take readings) that may produce inaccurate
results. If continued difficulty is found in obtaining a high percentage of
correctly exposed prints, the probe may be re-calibrated (see section 8).

BASIC CALIBRATION AND DATA ENTRY
The program consists of five paper channels, each with the
following structure:
CALIBRATION OF THE EXPOSURE-CONTRAST
PROBE
The ‘Calibration’ function allows the basic setting up of the
system to obtain the correct exposure times (density) and grade,
when using the probe.
Density calibration - ‘New Cal’ and ‘Cal Adj’
The density calibration factor ‘Cal’ is displayed on the control
unit in ‘Cal Adj’ mode. the value of ‘Cal’ is determined by
making test prints and is directly linked to exposure time
determined by the probe (it represents paper speed).
‘New Cal’ should be used to calibrate the probe for new batches of
paper. ‘Cal Adj’ is best used to reset the calibration to predetermined
values. For example, to reset to values determined under ’New Cal’
and then written on the paper box for reference.
Fine tuning can also be carried out by small adjustments of the ‘New Cal’
value to compensate for a drift in processing chemistry activity, for example.

Density calibration is only possible by using the following
procedure, during which a probe measurement must be made
when the control unit displays ‘Measure’.
To calibrate proceed as follows:
Select an average production negative of good tonal range which
you would expect to be printed at grade 2.5 and place in the
enlarger. Press ‘Focus’, adjust and focus an image of
approximately 20x25cm (8x10in) onto the baseboard. Set the
working aperture on the lens.
Select the paper channel.
Select ‘New Cal’ mode by keeping the ‘Paper’ button depressed
and by pressing the ‘–’ button once.
The ‘New Cal’ LED will light up and the display will show ‘Measure’.
With the room lights off, make a normal probe measurement (see section 7).
After releasing the probe key, the display will show the grade (2.5) and the
exposure time (which corresponds to the calibration value).
Make an exposure with the settings obtained and process the print.
Correct the test print by adjusting the exposure time using the ‘+/–’
buttons as required.
Note
When the exposure time is corrected, the calibration value will be
automatically adjusted (they are directly linked together).
Repeat steps 5 and 6 until the density of the test print is correct.
Select ‘Cal Adj’ by keeping the ‘Paper’ button depressed and
pressing the ‘–’ button once.
The ‘Cal Adj’ LED will light and the display will show the
calibration value derived during the previous procedure. This
calibration value represents the paper speed and for reference
should be noted down or written on the box of paper being used.
Return to the normal printing mode by keeping the ‘Paper’ button
depressed and by pressing the ‘+/–’ button twice.
If required, the density calibration value may be adjusted in ‘Cal
Adj’ mode by using the ‘+/–’ buttons. 30 units corresponds to 1 f-
stop (eg. reducing the calibration value by 30 will halve the
exposure time set).
Note
Changing the value in ‘Cal Adj’ only changes the exposure times
determined by the probe.

Grade calibration - ‘Contrast Adj’
This function allows the grade (contrast) value determined by the probe to
be offset by ± 30% (an adjustment of approximately ±1.5 grades).
It also enables personal taste to be taken into account and can provide
matching between two batches of paper.
A change to ‘Contrast Adj’ results in a print contrast being
obtained which is either higher or lower than the value
determined by the grade table. The grade correction function
only fully affects the grade values (as determined by the probe)
in the range 1.0 to 4.0.
The available offset from 1.0 towards 00 and from 4.0 towards
5.0, reduces as the extremes of the range are approached.
Select ‘Contrast Adj’ mode by keeping the ‘Paper’ button
depressed and by pressing the ‘–’ button twice.
The ‘Contrast Adj’ LED will light and the display will show the
contrast correction value in %. This will be 0 if no previous
correction has been made.
The correction value can be set from –30 to +30 using the +/–
buttons. + increases the contrast – lowers the contrast
Return to normal printing mode by keeping the ‘Paper’ button
depressed and pressing the ‘–’ button.
After switching to the normal printing mode, the system
automatically re-calculates the grade and exposure time
determined by the probe during calibration mode.
Whenever required, the contrast calibration value may be
adjusted in ‘Contrast Adj’ mode by using the ‘+/–’ buttons.
CHECKING OR SETTING UP A GRADE TABLE
The following example shows the procedure for setting or
checking data in a grade table. Values shown in this example
are from the table for channel 1 (see section 12).
Select the paper channel.
Call up the grade table by keeping the ‘Memory’ button
depressed and by pressing the ‘Grade’ button once.
The ‘Contrast’ LED will light and the display will show the paper
grade and the corresponding set value for the contrast (1st and
2nd columns in the grade table)
Adjust the contrast value by pressing the ‘+/–’ buttons.
Notes
The actual grade achieved on the print is determined by the
settings of the yellow and magenta filters. The contrast value

shown in the table enables the probe to calculate the correct grade
following measurements taken during a scanning cycle.
The contrast value can only be adjusted over a limited range, pre-
determined by the control unit, otherwise ‘Cont Err’ will be
displayed when the unit is returned to normal operating mode.
Change to the next paper grade step by pressing the ‘Grade’ button.
Repeat the above steps until you have adjusted or checked the
values for all paper grade steps (00 - 5.0)
Now change to the entering mode for the Yellow-filtration by keeping
the ‘Memory’ button depressed and by pressing the ‘Grade’ button. The
‘Yellow’ LED will light and the display will show the paper grade and
the corresponding set value for the Yellow-filtration.
(1st and 3rd columns in the grade table)
Adjust the Yellow-filtration by pressing the ‘+/–’ buttons.
Step through the paper grades by pressing the ‘Grade’ button as before.
Now change to the entering mode for the Magenta-filtration by keeping
the ‘Memory’ button depressed and by pressing the ‘Grade’ button. The
‘Magenta’ LED will light and the display will show the paper grade and
the corresponding set value for the Magenta filtration.
(1st and 4th columns in the grade table)
Adjust the Magenta-filtration by pressing the ‘+/–’ buttons.
Again, step through the grades using the ‘Grade’ button.
Now change to the entering mode for the density compensation by
keeping the ‘Memory’ button depressed and by pressing the ‘Grade’
button. The ‘Density’ LED will light and the display will show the paper
grade and the corresponding set value for the density compensation,
‘D-Comp’. ‘D-Comp’ enables automatic re-calculation of the exposure
time when changing grades to ensure a constant print density.
(1st and 5th columns in the grade table)
Adjust the value for the ‘D-Comp’ by pressing the ‘+/–’ buttons. For
example, +30 ‘D-Comp’ would double the exposure time from say 2.5
to 5.0 seconds. Note that the value of 0.00 corresponding to grade 2.5
cannot be amended. Step through each grade as before.
The checking or entering cycle for the grade table is now complete.
To return to the normal printing mode keep the ‘Memory’ button
depressed and press the ‘Grade’ button.
Note
When contrast, yellow, magenta or D-Comp mode has been
selected on the control unit (for checking or changing the set
values), pressing the ‘Clear’ button will return ALL values in that
column of the table to the factory settings.
