RMP400 basics
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 pre-travel variation to provide high accuracy, even when
used with long styli;
• a proven ten-fold improvement in life (10 million triggers);
• 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.
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.
• The ability to be used in applications where axial and radial reorientations are used, enabled by the
use of solid state accelerometers:
The auto-reset function is required and recommendations should be followed for optimum
metrology performance.
see Section 2, “RMP60 basics”

RMP400 installation guide
2.2
RMP400 basics
Getting started
Three multicolour probe LEDs provide visual indication of selected probe settings and status.
For example:
• Switch-on and switch-off methods
• Probe status – triggered or seated
• Battery condition
Batteries are inserted or removed as shown (for more information, see page 3.4, “Installing the
batteries”).
On insertion of batteries, the LEDs will begin to flash, starting with a LED check (for more information,
see page 4.1, “Reviewing the probe settings”).
System interface
The RMI and RMI-Q are integrated interfaces/receivers used to communicate between the RMP400
probe and the machine controller.
Trigger Logic™
Trigger Logic (for more information, see page 4.1, “Reviewing the probe settings”) 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.
A Trigger Logic app is available that simplifies this process with clear, interactive instructions and
informative videos and is available for download on the App Store and Google Play.
or
Current probe settings can also be reviewed by simply removing the batteries for a minimum
of 5 seconds, and then replacing them to activate the Trigger Logic review sequence (for more
information, see page 4.1, “Reviewing the probe settings”).

2.3
RMP400 basics
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 (hibernation mode is only applicable to “radio on”).
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.
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

RMP400 installation guide
2.4
RMP400 basics
NOTES:
In “radio on” mode, the switch-on time is user selectable “fast” or “standard” when using RMI-Q
(selection is made in RMI-Q). Otherwise the switch-on time is 1.7seconds.
For more information on the user selectable switch-on time when operating with RMI-Q, refer to the
RMI-Q radio machine interface installation guide (Renishaw part no. H-5687-8504).
In “radio on” mode, the switch-on time assumes a good radio communication link. In a poor radio
frequency (RF) environment this may rise to a maximum of 3seconds.
In “spin on” mode, the 1 second starts from the moment the spindle reaches 500 r/min.
The RMP400 must be on for a minimum of 1second before being switched off.

seconds (user configurable) after the
last probe trigger or reseat.
2.5 seconds
minimum. (The probe
must be stationary for
2.5 seconds minimum
after it has stopped
spinning.)

2.5
RMP400 basics
Enhanced trigger filter
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.
This feature is controlled by solid state accelerometers and is suitable for applications where axial and
radial reorientation of the probe is applied.
To achieve optimum metrology performance when the auto-reset function is turned on, a dwell is
recommended before making a programmed move that follows any reorientation of the probe.
When using a recommended carbon fibre stylus of up to 150 mm in length, a 0.2 second dwell is
necessary. In most applications the machine response time will adequately provide this.
When using a stylus longer than 150 mm, a heavy stylus or any other stylus configuration, it is
recommended that the RMP400 should be turned off during reorientation moves. (see page 2.10,
“Recommended styli”, for further information).
When in “auto-reset” mode, the probe will not trigger when moved below a speed of 3 mm/min.
NOTE: Speeds below 3 mm/min commonly occur when manually moving the probe using the
handwheel with a very ne feedrate.
Multiple probe mode
The RMP400 can be configured, using Trigger Logic, to allow multiple radio probes in “spin on/spin
off” to be used with a single RMI or RMI-Q.
Up to four RMP400 probes can be used with a single RMI-Q in “radio on/radio off” mode. For further
details of this functionality, refer to the RMI-Q radio machine interface installation guide (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”.

RMP400 installation guide
2.6
RMP400 basics
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 (for more
information, see page 4.2, “Multiple probe mode settings”).
All probes operating with a single RMI or RMI-Q must be set to the same “mode on” colour choice;
any multiple probes located on adjacent machines must all be set to an alternative “mode on” colour
choice.
NOTE: Each probe per “mode on” colour choice must be partnered with the RMI or RMI-Q. By
conguring multiple probes to a single “mode on” colour choice, all probes using this “mode on”
colour choice will have the same identity.
The probe to be partnered is partnered after selecting the multiple probe mode setting and choosing
the “mode on” option. (for more information, see page 4.6, “Changing the probe settings”).
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 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.
The addition of any further probe(s), or replacements, into a multi-probe installation can be achieved
through the reconfiguration of the probe to the same “mode on” colour choice.
Acquisition mode
System set-up is achieved using Trigger Logic and powering-on the RMI or RMI-Q.
Partnering is required during initial system set-up. Further partnering is only required if the RMP400,
RMI or RMI-Q is changed.
NOTES:
Systems using the RMI-Q can be partnered with up to four RMP400 probes manually. Alternatively,
partnering to an RMI-Q, 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 of charge visit:
www.renishaw.com/mtpsupport/renikey
Partnering by ReniKey is not available for the 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.

1Speeds below 3 mm/min commonly occur when manually moving the probe using the handwheel with a very ne
feedrate.
2 Performance specification is tested at a standard test velocity of 240 mm/min (9.45 in/min) with a 50 mm (1.97 in)
carbon fibre stylus. Significantly higher velocity is possible depending on application requirements.
3 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, machine deceleration and latency.
RENGAGE equipped probes offer ultra-low trigger forces.
4 These are the factory settings; manual adjustment is not possible.
5Stylus overtravel force in the XY plane occurs 70 μm (2755.91 µin) after the trigger point and rises by 0.1 N/mm,
10gf/mm (9.1 ozf/in) until the machine tool stops (in the high force direction and using a 50 mm (1.97 in) carbon
fibre stylus).
6Stylus overtravel force in +Z direction occurs 1.0 μm (39.37 μin) after the trigger point and rises by 0.6 N/mm,
61 gf/mm (54.8 oz/in) until the machine tool stops.
