reliable service.

Safety

This symbol adjacent to another symbol, terminal or operating device indicates that the operator

must refer to an explanation in the Operating Instructions to avoid personal injury or damage to the

meter.

This WARNING symbol indicates a potentially hazardous situation, which if not avoided, could

result in death or serious injury.

This CAUTION symbol indicates a potentially hazardous situation, which if not avoided, may result

damage to the product.

This symbol advises the user that the terminal(s) so marked must not be connected to a circuit point

at which the voltage with respect to earth ground exceeds (in this case) 1000 VAC or VDC.

This symbol adjacent to one or more terminals identifies them as being associated with ranges that

may, in normal use, be subjected to particularly hazardous voltages. For maximum safety, the meter

and its test leads should not be handled when these terminals are energized.

This symbol indicates that a device is protected throughout by double insulation or reinforced

insulation.

AUTORANGING/MANUAL RANGE SELECTION

When the meter is first turned on, it automatically goes into AutoRanging. This automatically selects the best range for

the measurements being made and is generally the best mode for most measurements. For measurement situations

requiring that a range be manually selected, perform the following:

1. Press the RANGE key. The “AUTO” display indicator will turn off.

2. Press the RANGE key to step through the available ranges until you select the range you want.

3. To exit the Manual Ranging mode and return to Autoranging, press and hold the RANGE key for 2 seconds.

Note: Manual ranging does not apply for the Temperature functions.

MAX/MIN

1. Press the MAX/MIN key to activate the MAX/MIN recording mode. The display icon "MAX" will appear. The meter

will display and hold the maximum reading and will update only when a new “max” occurs.

2. Press the MAX/MIN key again and the display icon "MIN" will appear. The meter will display and hold the minimum

reading and will update only when a new “min” occurs.

3. To exit MAX/MIN mode press and hold the MAX/MIN key for 2 seconds.

Relative mode

The relative measurement feature allows you to make measurements relative to a stored reference value. A reference

voltage, current, etc. can be stored and measurements made in comparison to that value. The displayed value is the

difference between the reference value and the measured value.

1. Perform the measurement as described in the operating instructions.

2. Press and Hold the REL button to store the reading in the display and the "REL" indicator will appear on the display.

3. The display will now indicate the difference between the stored value and the measured value.

4. Press and Hold the REL button to exit the relative mode.

PEAK HOLD

The Peak Hold function captures the peak AC voltage or current. The meter can capture negative or positive peaks as

fast as 1 millisecond in duration. Press the PEAK button. “PEAK MAX” will appear in the display, Press the PEAK

key again and the display icon "PEAK MIN" will appear. The meter will update the display each time a higher

positive and nagetive peak occurs. Press and hold the PEAK button for 2 seconds to exit the mode.

DISPLAY BACKLIGHT

Press the HOLD/ key for >2 second to turn the backlight on. The backlight will automatically turn off after 10

seconds.

HOLD

The hold function freezes the reading in the display. Press the HOLD key momentarily to activate or to exit the HOLD

function.

LOW BATTERY INDICATION

When the low battery

icon appears in the display, the battery should be replaced.

AUTO POWER OFF

The auto off feature will turn the meter off after 15 minutes. To disable the auto power off feature, hold down the

MODE button and turn the meter on. “APO d” will appear in the display. Turn the meter off and then on again to

re-enable the auto power off feature.

Maintenance

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back

cover or the battery or fuse covers.

WARNING: To avoid electric shock, do not operate your meter until the battery and fuse covers are in place and

fastened securely.

This MultiMeter is designed to provide years of dependable service, if the following care instructions are performed:

1. KEEP THE METER DRY. If it gets wet, wipe it off.

2. USE AND STORE THE METER IN NORMAL TEMPERATURES. Temperature extremes can shorten the life of the

electronic parts and distort or melt plastic parts.

3. HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the electronic parts or the case.

4. KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth. DO NOT use chemicals, cleaning

solvents, or detergents.

5. USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND TYPE. Remove old or weak batteries so

they do not leak and damage the unit.

6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries should be removed to prevent

damage to the unit.

BATTERYINSTALLATION

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery

cover.

1. Turn power off and disconnect the test leads from the meter.

2. Open the rear battery cover by removing two screws (B) using a Phillips head screwdriver.

3. Insert the battery into battery holder, observing the correct polarity.

4. Put the battery cover back in place. Secure with the screws.

WARNING: To avoid electric shock, do not operate the meter until the battery cover is in place and fastened

securely.

NOTE: If your meter does not work properly, check the fuses and batteries to make sure that they are still good and that

they are properly inserted.

REPLACING THE FUSES

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the meter

cover.

1. Disconnect the test leads from the meter.

2. Remove the battery cover (two “B” screws) and the battery.

3. Remove the six “A” screws securing the rear cover.

4. Gently remove the old fuse and install the new fuse into the holder.

5. Always use a fuse of the proper size and value (0.5A/1000V fast blow for the 600 mA range 10A/1000V fast blow

for the 10A range

6. Replace and secure the rear cover, battery and battery cover.

WARNING: To avoid electric shock, do not operate your meter until the fuse cover is in place and fastened securely.
