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 0V/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;
• all screens must be connected as outlined in 
the user instructions;
• cables must not be routed alongside high 
current sources, i.e. motor power supply 
cables etc, or be near high speed data lines;
• cable lengths should always be kept to a 
minimum.

2.1
Introduction
The RTS is a tool setter with radio transmission 
suitable for use on small to large machining 
centres, or where line-of-sight between probe and 
receiver is difficult to achieve.
The RTS forms part of Renishaw’s family of new 
generation radio transmission probes. It has been 
designed to comply with worldwide standards 
and operates in the 2.4 GHz band. It delivers 
interference-free transmission through the use of 
FHSS (Frequency Hopping Spread Spectrum). 
This allows many systems to operate in the same 
machine shop without risk of cross-interference.
All RTS settings are configured using Trigger 
Logic™. This technique enables the user to 
review and subsequently change probe settings 
by deflecting the stylus whilst observing the LED 
indication.
Getting started
A multicolour LED provides visual indication of 
selected probe states:
• trigger filter setting;
• tool setter status - triggered or seated;
• battery condition.
Batteries are inserted or removed as shown in 
Section 5, "Maintenance" page 5.2.
On insertion of the batteries, the LED will begin 
to flash (see Section 4, "Trigger Logic™" page 
4.1). 
System interface
The RMI and RMI-Q are combined antenna, 
interface and receiver units used to communicate 
between the RTS and the machine controller.
Trigger Logic™
All RTS settings are configured using the Trigger 
Logic™ technique.
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 deflection 
(triggering) to systematically lead the user through 
the available choices to allow selection of the 
required mode options.
Current probe settings can be reviewed by 
simply removing the batteries for a minimum of 
5 seconds, and then replacing them to activate 
the Trigger Logic™ review sequence.
Modes of operation
The RTS can be in one of three modes:
Standby mode: where the RTS is awaiting a 
switch-on signal.
Operational mode: activated by the switch-on 
method described on the next page, the RTS is 
ready for use.
Configuration mode: where Trigger Logic™ may 
be used to configure the following probe settings.
RTS basics 

RTS installation guide
2.2
RTS basics
Configurable settings
Enhanced trigger filter
Probes subjected to high levels of vibration or 
shock loads may trigger without having been 
contacted. The enhanced trigger filter improves 
the probe’s resistance to these effects.
When the filter is enabled, a constant nominal 
6.7 ms delay is introduced to the probe output.
It may be necessary to reduce the approach 
speed to allow for the increased stylus overtravel 
during the extended time delay. The RTS is factory 
set to Enhanced trigger filter off.
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 RTS or RMI/RMI-Q is changed.
Partnering will not be lost by reconfiguration of 
probe settings or when changing batteries.
Partnering can take place anywhere within the 
operating envelope.
Switch-on
When the RTS is used with an RMI the turn-on 
time is 1.0 second. When the RTS is used with an 
RMI-Q the turn-on time can be configured, in the 
RMI-Q, to either 0.5 seconds or 1.0 second. For 
best battery life, select 1.0 second turn-on time.
A timer automatically switches the probe off 
90 minutes after the last trigger if not turned 
off by an M code.
NOTE:  After being switched on, the RTS must be 
on for 1.0 second minimum before being switched 
off.

2.3
RTS basics
Operation Recommended rotating tool feed rates
Cutters should be rotated in reverse to the 
cutting direction. Renishaw tool setting software 
calculates speeds and feeds automatically using 
the following information.
First touch – machine spindle rev/min 
Rev/min for the first move against the probe 
stylus:
Diameters below 24 mm, 800 rev/min is used.
Diameters from 24 mm to 127 mm, rev/min is 
calculated using a surface speed of 60 m/min 
(197 ft/min).
Diameters above 127 mm, 150 rev/min is used.
First touch – machine feed rate
The feedrate (f) is calculated as follows:
f = 0.16 × rev/min   f units mm/min (diameter set)
f = 0.12 × rev/min  f units mm/min (length set)
Second touch – machine feed rate
800 rev/min, 4 mm/min (0.16 in/min) feedrate.
The tool is driven in the machine Z axis for tool 
length measurements and broken tool detection.
Rotating tools are set in the machine’s X and Y 
axes for tool radius offsets.
Screw adjusters allow the stylus to be aligned with 
the machine’s axes.
Software routines
Software routines for tool setting are available 
from Renishaw for various machine controllers 
and are described in data sheet H-2000-2289.
In addition, data sheet H-2000-2298 lists available 
Renishaw software programs. Both data sheets 
can be downloaded from www.renishaw.com/
inspectionplus.
Achievable set-up tolerances
The tolerances to which tools can be set depend 
upon the flatness and parallelism of the stylus tip 
setting. A value of 5 µm (0.0002 in) front to back 
and side to side is easily achievable over the flat 
portion of the stylus tip, and 5 µm (0.0002 in) 
parallelism is easily achievable with the axes of a 
square tip stylus. This setting accuracy is sufficient 
for the majority of tool setting applications.

pass through very small gaps and machine tool 
windows. This allows easy installation, either 
inside or outside the machine enclosure, so long 
as the probe and transmitter are kept within the 
performance envelope specified and that the RMI 
signal LED remains on at all times. 
Coolant and swarf residue accumulating on the 
RTS and RMI may have a detrimental effect 
on transmission performance. Wipe clean as 
often as is necessary to maintain unrestricted 
transmission. 
When in operation, do not touch either the RMI 
cover or the RTS glass window with your hand as 
this can also affect transmission performance.
Some reduction in range may result when 
operating in temperatures of 0 °C to +5 °C 
(+32 °F to +41 °F) and +50 °C to +60 °C 
(+122 °F to +140 °F).

Performance envelope when 
using the RTS with an RMI/RMI-Q
RTS - RMI/RMI-Q positioning
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/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/RMI-Q, the signal 
quality is displayed on an RMI/RMI-Q signal LED. 
Ensure that the signal LED indicates a green or 
yellow (good) signal strength when the RTS is 
operating or in stand-by mode (see following note 
regarding 'hibernate mode').
NOTE: RMI/RMI-Q installation with RTS. 
RTS has a built-in hibernate mode (battery saving 
mode) that saves battery life when the RMI/RMI-Q 
is unpowered. The RTS goes into hibernate mode 
30 seconds after the RMI/RMI-Q is unpowered 
(or the RTS is out of range). When in hibernate 
mode, the RTS checks for a powered RMI/RMI-Q 
every 30 seconds. If found, the RTS goes from 
hibernate mode to stand-by mode, ready for an 
M code. If the RTS goes out of range, for example 
if the RTS is fitted to a pallet which is removed 
from the machine, once the RTS is back in range 
the system will automatically re-synchronise 
within 30 seconds (worst case). Allowance must 
be made within the machine controller program for 
this.
Performance envelope
The RTS and RMI/RMI-Q must be within each 
other's performance envelope as shown below. 
The performance envelope shows line-of-sight 
performance, however radio transmission does 
not require this providing a reflected path (of less 
than 15 m (49.2 ft)) is available.

In the event of the break stem breaking, the 
captive link ties the stylus to the probe, which 
prevents the stylus falling into the machine.
NOTE:  Always hold the support bar in position 
to counteract twisting forces and avoid over-
stressing the stylus break stem.

Mounting the RTS on a machine table
1.  Select a position for the RTS on the 
machine table. Position to minimise the 
possibility of collision and ensure the radio 
window faces towards the receiver.
2.  Separate the base from the body by 
slackening four screws 1 and two screws 2 
using a 2.5 mm AF hexagon key.
3.  Fit the cap head bolt and T nut (not supplied 
by Renishaw) and tighten to secure the 
base to the machine table.
NOTE:  A smaller washer should be fitted for a 
smaller bolt by disassembling and separating the 
base plates.
4.  Refit the body onto the base and tighten 
screws 1 and 2. If a square stylus is 
fitted, and fine rotational adjustment is 
required,  see "Square stylus only", 
"Coarse rotational adjustment" and "Fine 
rotational adjustment" pages 3.9 - 3.12 
before tightening screws 2.
5.  Fit the stylus. See "Fitting the stylus, 
break stem and captive link" page 3.4.
Dowel pins (shown on page 2.4)
Two locating pins (supplied in the tool kit) may be 
fitted on installations where there is a requirement 
to remove and remount the tool setter.
To fit the dowel pins, drill two holes in the machine 
table to correspond with the two probe base holes. 
Place the dowel pins in the holes and refit the 
probe base.

Calibrating the RTS
Why calibrate a probe?
A 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 you calibrate your 
probe in the following circumstances:
•  when a probe system is to be used for the 
first time;
•  when a new stylus is fitted to the probe;
•  when it is suspected that the stylus has 
become distorted or that the probe has  
crashed;
•  at regular intervals to compensate for 
mechanical changes of your machine tool.
When your probe is assembled and mounted 
on the machine table, it is necessary to align 
the stylus faces with the machine axes to avoid 
probing errors when setting tools. It is worth taking 
care with this operation – you should try to get the 
faces aligned to within 0.010 mm (0.0004 in) 
for normal use. This is achieved by manually 
adjusting the stylus with the adjusting screws 
provided, and using a suitable instrument such as 
a DTI clock mounted in the machine spindle.
When the probe has been correctly set up on 
the machine, it is time to calibrate the probe. 
Calibration cycles are available from Renishaw 
for this task. The purpose is to establish the probe 
stylus measuring face trigger point values under 
normal measuring conditions.
Calibration should be run at the same speed as 
probing.
The calibration values are stored in macro 
variables for computation of the tool size during 
tool setting cycles.
Values obtained are axis trigger positions 
(in machine co-ordinates). Any errors due to 
machine and probe triggering characteristics 
are automatically calibrated out in this way. 
These values are the electronic trigger positions 
under dynamic operating conditions, and 
not necessarily the true physical stylus face 
positions.
NOTE:  
Poor repeatability of probe trigger point values 
indicates that either the probe/stylus assembly 
is loose or a machine/probe fault exists. Further 
investigation is required.

RTS – RMI/RMI-Q partnership
System set-up is achieved using Trigger Logic™ 
and powering on the RMI/RMI-Q. Partnering is 
only required during initial system set-up. Further 
partnering is only required if either the RTS or 
RMI/RMI-Q is changed.
Partnering will not be lost by reconfiguring the 
probe settings or when changing batteries. 
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".
Deflect the stylus to select 'Acquisition 
mode on'. Ensure this is done within 
10 seconds of the RMI/RMI-Q signal

NOTES: 
Due to the nature of Lithium Thionyl Chloride batteries, if a 'low battery' LED sequence is ignored 
or overlooked, then it is possible for the following sequence of 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 re-activates 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. 
4.   Again, the batteries discharge and the probe ceases to function. 
5.   Again, the batteries recover sufficiently to provide the probe with power and the sequence    
   repeats  itself.

Maintenance
You may undertake the maintenance routines 
described in these instructions.
Further dismantling and repair of Renishaw

Maintenance
Routine maintenance
The probe is a precision tool and must be 
handled with care.
Ensure the probe is firmly secured to its 
mounting.
The probe requires minimal maintenance as it is 
designed to operate as a permanent fixture on 
CNC machining centres, where it is subject to a 
hot chip and coolant environment.
1.  Do not allow excessive waste material to 
build up around the probe.
2   Swarf accumulating on the transmission 
window will have a detrimental effect on 
transmission performance, see page 5.1. 
3.  Keep all electrical connections clean.
4.  The probe mechanism is protected by an 
outer metal eyelid seal and an inner flexible 
diaphragm seal. 
Approximately once a month, inspect the probe 
inner diaphragm seal, see page 5.5. If it is 
pierced or damaged please contact Renishaw.
The service interval may be extended or reduced 
depending on experience.

4.  Inspect the diaphragm seal for signs of 
piercing or damage. In the event of damage, 
return the probe to your supplier for repair, as 
coolant entering the probe mechanism could 
cause the probe to fail.
5.  Refit the spring and metal eyelid (the spring’s 
largest diameter is against the metal eyelid).
6.  Refit the remaining components.
