Information to the user
The RMP400 is supplied with two nonrechargeable ½AA lithium-thionyl chloride
batteries (approved to BS EN 62133:2013
[IEC 62133:2012]). Once the charge in these
batteries is depleted, do not attempt to recharge
them.
• If a battery is damaged, exercise caution when
handling it.
Please ensure that you comply with international
and national battery transport regulations when
transporting batteries or the products.
Lithium batteries are classified as dangerous
goods and strict controls apply to their shipment
by air. To reduce the risk of shipment delays, if you
need to return the products to Renishaw for any
reason, do not return any batteries.
In all applications involving the use of machine
tools or CMMs, eye protection is recommended.
The use of this symbol on the batteries,
packaging or accompanying documents indicates
that used batteries should not be mixed with
general household waste. Please dispose of
the used batteries at a designated collection
point. This will prevent potential negative effects
on the environment and human health which
could otherwise arise from inappropriate waste
handling. Please contact your local authority or
waste disposal service concerning the separate
collection and disposal of batteries. All lithium and
rechargeable batteries must be fully discharged or
protected from short circuiting prior to disposal.
Please ensure replacement batteries are of the
correct type and are fitted in accordance with
the instructions in this manual (see page 5.2,
“Changing the batteries”), and as indicated on the
product. For specific battery operating, safety and
disposal guidelines, please refer to the battery
manufacturer’s literature.
• Ensure that all batteries are inserted with the
correct polarity.
• Do not store batteries in direct sunlight or rain.
• Do not heat or dispose of batteries in a fire.
• Avoid forced discharge of the batteries.
• Do not short-circuit the batteries.
• Do not disassemble, pierce, deform or apply
excessive pressure to the batteries.
• Do not swallow the batteries.
The RMP400 has a glass window. Handle with
care if broken to avoid injury.
Information to the machine supplier/
installer
It is the machine supplier’s responsibility to ensure
that the user is made aware of any hazards
involved in operation, including those mentioned
in Renishaw product literature, and to ensure
that adequate guards and safety interlocks are
provided.
Under certain circumstances, the probe signal
may falsely indicate a probe seated condition. Do
not rely on probe signals to halt the movement of
the machine.
Information to the equipment installer
All Renishaw equipment is designed to comply
with the relevant EC and FCC regulatory
requirements. It is the responsibility of the
equipment installer to ensure that the following
guidelines are adhered to, in order for the product
to function in accordance with these regulations:
• any interface MUST be installed in a position
away from any potential sources of electrical
noise, i.e. power transformers, servo drives etc;
• all 0 V/ground connections should be
connected to the machine “star point” (the “star
point” is a single point return for all equipment
ground and screen cables). This is very
important and failure to adhere to this can
cause a potential difference between grounds;

RMP400 basics
2.1
Introduction
The RMP400 offers an unrivalled combination
of size, accuracy, reliability and robustness
and, allows high-accuracy probing on small to
medium machining centres or other machines
where line-of-sight problems affect optical signal
transmission.
Successfully combining patented RENGAGE™
strain gauge technology with the patented
frequency hopping radio transmission system of
the RMP40, the RMP400 provides existing probe
users with a simple upgrade to solid-state strain
gauge technology and all the associated benefits
this brings:
• excellent 3D performance to allow probing of
contoured surfaces;
• improved repeatability in all probing directions;
• a low triggering force combined with low pretravel variation to provide high accuracy, even
when used with long styli;
Performing this calibration for every 3D
direction can be time-consuming.
The RMP400 has almost no pre-travel
variation, so a single calibration value may be
used for any probing angle in 2D or 3D. This
results in a vastly reduced calibration time. An
additional benefit is a corresponding reduction
in errors introduced by environmental changes
within the machine during a long calibration
cycle.

recommendations should be followed for

• the elimination of reseat failures;
• high resistance to machine tool vibration;
• resistance to shock and false triggering
through the use of solid state accelerometers.
In addition to providing high-accuracy
measurement on your machine tool, the RMP400
also offers:
• Faster calibration:
On complex 3D parts, it is common to
measure in several different directions. Each
direction of a standard mechanical probe must
be calibrated, to ensure that the pre-travel
variation is compensated in the measurement.
• Switch-on and switch-off methods
• Probe status – triggered or seated
• Battery condition
Batteries are inserted or removed as shown (see
page 3.5, “Installing the batteries”) for further
information).
On insertion of batteries, the LEDs will begin
to flash (see page 4.1, “Reviewing the probe
settings”).

System interface
2.2
The RMI and RMI-Q are integrated interfaces/
receivers used to communicate between the
RMP400 probe and the machine control.
Trigger Logic™
Trigger Logic (see Section 4, “Trigger Logic™”) is
a method that allows the user to view and select
all available mode settings in order to customise
a probe to suit a specific application. Trigger
Logic is activated by battery insertion and uses
a sequence of stylus deflections (triggering) to
systematically lead the user through the available
choices to allow selection of the required mode
options.
Configurable settings
Switch-on/switch-off methods
The following switch-on/switch-off options are
user-configurable.
• Radio on/Radio off
• Radio on/Timer off
• Spin on/Spin off
• Spin on/Timer off
A Trigger Logic app is available that simplifies this
process with clear, interactive instructions and
informative videos and is available for download
on the following app stores.
or
Current probe settings can be reviewed by
simply removing the batteries for a minimum of
five seconds, and then replacing them to activate
the Trigger Logic review sequence.
Probe modes
The RMP400 probe can be in one of three modes:
Standby mode – Probe is waiting for a switch-on
signal.
NOTE: The RMP400 will enter hibernation mode
should the system interface be powered off or
out of range for a period of 30 seconds (only
applicable to “radio on” mode).
Operational mode – When activated by one of
the switch‑on methods, the probe is switched on
and ready for use.
Configuration mode – Ready to change the
probe settings using Trigger Logic.

RMP400 switch-on method
In “spin on” mode, the one second starts from
the moment the spindle reaches 500 rev/min.
The RMP400 must be on for a minimum of

switch-on time when operating with RMI-Q, please
refer to the installation guide RMI-Q radio machine
interface (Renishaw part no. H-5687-8504).
In “radio on” mode, the switch-on time assumes
a good radio communication link. In a poor RF
environment this may rise to a maximum of
3.0 seconds.

Enhanced trigger filter
2.4
Probes subjected to high levels of vibration or
shock loads may output signals without having
contacted any surface. The enhanced trigger filter
improves the probe’s resistance to these effects.
When the filter is enabled, a constant 8 ms or
16 ms delay is introduced to the probe’s output.
The factory setting is 8 ms. If false triggering is
noticed, then consider increasing the filter delay to
16 ms.
Auto-reset function
In previous strain gauge products, the probe was
required to be turned off during reorientation
moves. The auto-reset function in the RMP400
can compensate for stylus forces, resulting from
changes in probe orientation, that can cause the
probe to trigger.
Up to four RMP400s can be used with a single
RMI-Q in “radio on/radio off” mode. For further
details of this functionality, please refer to the
installation guide RMI-Q radio machine interface
(Renishaw part no. H-5687-8504).
NOTES:
Multiple probe mode is a function of the RMP400,
as such, the option will not appear when the
“radio on” option has been selected.
RMP400 probes which are set to “multiple probe
mode on” can coexist alongside any number of
RMP400 probes set to “multiple probe mode off”.
To allow multiple radio probes to work in close
proximity, and with a single RMI or RMI-Q,
16 choices of “mode on” colours are available,
each representing a different machine tool
installation. (see page 4.2, “Multiple probe

needs to be partnered with the RMI or RMI-Q.
By configuring multiple probes to a single “mode
on” colour choice, all probes using this “mode on”
colour choice will have the same identity.
When using a heavy stylus configuration, or a
stylus longer than 150 mm, it is recommended
that the RMP400 should be turned off during
reorientation moves.
The probe to be partnered is partnered after
selecting the multiple probe mode setting and
choosing the “mode on” option. (see page 4.4,
“Changing the probe settings”).
Multiple probe mode
There is no limit to the number of probes that can
be used with a single RMI or RMI-Q so long as
they all have the same “mode on” colour choice.
All RMP400 probes are factory set to “mode off”.
The RMP400 can be configured, using Trigger
Logic, to allow multiple radio probes in “spin on/
spin off” or “shank on/shank off” to be used with a
single RMI or RMI-Q.
The addition of any further probe(s) into a single
probe installation will require that all probes are
reconfigured to the same “mode on” colour choice
and that one of the probes is then repartnered
with the RMI or RMI-Q.
Draft 5 16/04/18
Acquisition mode
System set-up is achieved using Trigger Logic and
powering-on the RMI or RMI-Q.
Partnering is only required during initial system
set-up. Further partnering is only required if either
the RMP400 or RMI/RMI-Q is changed.
NOTES:
Systems using the RMI-Q can be partnered with
up to four RMP400s manually. Alternatively this
can be achieved by using ReniKey; a Renishaw
machine macro cycle which does not require the
RMI-Q to be power cycled.
For more information or to download ReniKey free

www.renishaw.com/mtpsupport/renikey
Partnering by ReniKey is not available for RMI.
Partnering will not be lost by reconfiguration of
probe settings or when changing batteries, except
where multiple probe mode is selected.
Partnering can take place anywhere within the
operating envelope.

Note 2
Trigger force, which is critical in some applications, is the force exerted on the component by the stylus when the
probe triggers. The maximum force applied will occur after the trigger point (overtravel). The force value depends on
related variables including measuring speed and machine deceleration. RENGAGE™ equipped probes offer ultralow trigger forces.

The featured range of solid carbon fibre styli
ensure the best possible performance of the
RMP400.
It is possible that the featured range of solid
carbon fibre styli may not be suitable for every
RMP400 application and that it may be necessary
to select specialised styli configurations to meet
specific application requirements.
In applications where specialised styli are to be
used, it may be beneficial to reduce the speed of
probing moves. It has been seen in some cases
that specialist styli configurations do not exhibit
the probing characteristics and performance
that would have otherwise been expected and
achieved when using standard styli. Reducing the
speed of the probing move may, in some cases,
improve the performance of the probe.
When selecting components for an application
specific stylus, it is recommended that
a configuration with the least number of
components is chosen. The stylus diameter
should always be as large as possible and the
overall stylus length kept to a minimum. If a stem
with a reduced diameter is required, then it is
recommended that an M4 stem with a short length
and reduced diameter is selected.

Radio transmission does not require line-of-sight
between the probe and interface as it works
via reflected paths, and will pass through gaps
and machine tool windows. This allows easy
installation, either inside or outside the machine
enclosure, as long as the probe and RMI or
RMI-Q are kept within the performance envelope
shown overleaf.
Coolant and swarf residue accumulating on
the RMP400 and RMI or RMI-Q may have a
detrimental effect on transmission performance.

Positioning the RMP400 and RMI or

3.2
The probe system should be positioned so that
the optimum range can be achieved over the full
travel of the machine’s axes. Always face the front
cover of the RMI or RMI-Q in the general direction
of the machining area and the tool magazine,
ensuring both are within the performance
envelope shown below. To assist in finding the
optimum position of the RMI or RMI-Q, the signal
quality is displayed on an RMI or RMI-Q signal
LED.
NOTE: Installing the RMP400 and RMI or RMI-Q
with the RMP400 in radio-on configuration
The RMP400 has a built-in hibernation mode
(battery-saving mode) that saves battery life
when the RMI or RMI-Q is unpowered in radio-on
(radio-off or timer-off) configurations. The RMP400
goes into hibernation mode 30 seconds after
the RMI or RMI-Q is unpowered (or the RMP400
is out of range). When in hibernation mode, the
RMP400 checks for a powered RMI or RMI-Q
every 30 seconds. If found, the RMP400 goes
from hibernation mode to standby mode, ready for
radio‑on.
Performance envelope
The RMP400 and RMI or RMI-Q must be within
each other’s performance envelope, as shown
below. The performance envelope shows line-ofsight performance, however, this is not necessary
for the RMP400 radio transmission as it will
operate with any reflected radio path provided
that the reflected path length does not exceed the
15 m (49.2 ft) operating range.

Why calibrate a probe?
A spindle probe is just one component of the
measurement system which communicates with
the machine tool. Each part of the system can
introduce a constant difference between the
position that the stylus touches and the position
that is reported to the machine. If the probe is
not calibrated, this difference will appear as an
inaccuracy in the measurement. Calibration of the
probe allows the probing software to compensate
for this difference.
During normal use, the difference between the
touch position and the reported position does
not change, but it is important that the probe is
calibrated in the following circumstances:
• when a probe system is to be used for the first
time;
• when the enhanced trigger filter delay is
Calibrating in a bored hole or on a
turned diameter
Calibrating a probe, either in a bored hole or on
a turned diameter of known size, automatically
stores values for the offset of the stylus ball to
the spindle centre line. The stored values are
then used automatically in the measuring cycles.
Measured values are compensated by these
values so that they are relative to the true spindle
centre line.
Calibrating in a ring gauge or on a
datum sphere
Calibrating a probe either in a ring gauge or
on a datum sphere with a known diameter
automatically stores one or more value for the
radius of the stylus ball. The stored values are
then used automatically by the measuring cycles
to give the true size of the feature. The values are
also used to give true positions of single surface
features.
changed;
• when a new stylus is fitted to the probe;
• when it is suspected that the stylus has
become distorted or that the probe has been
crashed;
• at regular intervals to compensate for
mechanical changes of your machine tool;
• if repeatability of relocation of the probe shank
is poor. In this case, the probe may need to be
recalibrated each time it is selected.
It is good practice to set the tip of the stylus oncentre, because this reduces the effect of any
variation in spindle and tool orientation (see page
3.6, “Stylus on-centre adjustment”). A small
amount of run-out is acceptable, and can be
compensated for as part of the normal calibration
process.
NOTE: The stored radius values are based on the
true electronic trigger points. These values are
different from the physical sizes.
Calibrating the probe length
Calibrating a probe on a known reference surface
determines the length of the probe, based on
the electronic trigger point. The stored value for
length is different from the physical length of the
probe assembly. Additionally, the operation can
automatically compensate for machine and fixture
height errors by adjusting the probe length value
that is stored.
Three different operations are to be used when
calibrating a probe. They are:
• calibrating either in a bored hole or on a turned
diameter of known position;
• calibrating either in a ring gauge or on a datum
sphere;
Draft 5 16/04/18
• calibrating the probe length.

Probe partnering function
4.4
The probe partnering function enables the
RMP400 to be partnered with the RMI or RMI-Q
independently of the configuration process for
other probe settings. To partner RMP400 with
RMI or RMI-Q, insert the batteries or, if they
have already been installed, remove them for five
seconds and then refit them.
Following an LED check, the RMP400 will
proceed to show the probe settings, this will end
with “Probe status” being displayed. If the battery
power is good, probe status will be eight green
flashes. If battery power is low, each green flash
will be followed by a blue flash.
Whilst the “Probe status” is being displayed,
deflect and immediately release the stylus to
enter “Acquisition mode”.
“Acquisition mode off” will be displayed as a
sequence of light blue flashes, at this point the
RMI or RMI-Q must be turned on.
On the RMP400 select “Acquisition mode on”
by deflecting the stylus for less than 4 seconds.
After a successful acquisition, the RMP400 will
timeout after 8 seconds and then go into standby.
If “Acquisition mode on” is not selected, the
RMP400 will timeout after 120 seconds and then
go into standby (see page 4.10, “RMP400 – RMI
partnership”) or (see page 4.11, “RMP400 –
RMI-Q partnership”).

To reset the probe
RMP400 features a master reset function to assist 1.
user’s who have mistakenly changed the probe
settings into an unintended state.
2.
The application of the master reset function will
clear all current probe settings and return the
probe to default settings.
The default settings are as follows:
• Radio switch-on
• Auto-reset on, Enhanced trigger filter on 8 ms
• Hibernation mode on 30 s
• Multiple probe mode off
1.
From within the Trigger Logic menu, hold the
stylus deflected for 20 seconds. After this
the status LEDs will proceed to flash yellow
eight times. A confirmation for master reset
is required, if nothing is done the probe will
timeout.
To confirm that a master reset is required,
release the stylus and then hold the stylus
deflected again until the eight yellow flash
sequence has ended. This action will clear
all probe settings and return the probe to
default settings. Following an LED check the
RMP400 will then go back into Trigger Logic
and will display “Switch-on method”.
• Radio switch-off
The default settings may not be representative of
the required probe settings. Further configuration
of RMP400 may subsequently be necessary to
achieve the required probe settings.
First enter into the Trigger Logic™ menu and
ensure that the stylus is no longer deflected.
3.
Further configuration using Trigger Logic may
be necessary to achieve the required probe
settings.

System set-up is achieved using Trigger Logic
and powering the RMI. Partnering is only required
during initial system set-up. Further partnering
will be required if either the RMP400 or RMI
is changed, or if a system is reconfigured for
multiple probes (multiple probe mode).
Partnering will not be lost by reconfiguring the
probe settings or when changing batteries, except
where multiple probe mode is selected. Partnering
can take place anywhere within the operating
envelope.
In configuration mode, configure the probe
settings as required until you reach the
“Acquisition mode” menu, which defaults to
“Acquisition mode off”.

events to occur:
1.
When the probe is active, the batteries
discharge until battery power becomes too
low for the probe to operate correctly.
2.
The probe stops functioning, but then
reactivates as the batteries recover
sufficiently to provide the probe with power.
3.
The probe begins to run through the LED
review sequence (see page 4.1, “Reviewing

Again, the batteries discharge and the probe
ceases to function.
Again, the batteries recover sufficiently

5.1
Maintenance
Cleaning the probe
You may undertake the maintenance routines
described in these instructions.
Wipe the window of the probe with a clean cloth
to remove machining residue. This should be
done on a regular basis to maintain optimum
transmission.
Further dismantling and repair of Renishaw
equipment is a highly specialised operation, which
must be carried out at an authorised Renishaw
Service Centre.
Equipment requiring repair, overhaul or attention
under warranty should be returned to your
supplier.
CAUTION: The RMP400 has a glass window.
Handle with care if broken to avoid injury.
Draft 5 16/04/18
Maintenance
Changing the batteries
CAUTIONS:
Do not leave dead batteries in the probe.
When changing batteries, do not allow coolant or
debris to enter the battery compartment.
5.2
When changing batteries, check that the battery
polarity is correct.
Take care to avoid damaging the battery cassette
gasket.
Only use specified batteries.
CAUTION: Please dispose of dead batteries in
accordance with local regulations. Never dispose
of batteries in a fire.
Draft 5 16/04/18
3
After removing the old batteries, wait more than
5 seconds before inserting the new batteries.
Do not mix new and used batteries or battery
types, as this will result in reduced life and
damage to the batteries.
Always ensure that the cassette gasket and
mating surfaces are clean and free from dirt
before reassembly.
If dead batteries are inadvertently inserted, the
