3. INTRODUCTION
3.1. PRODUCT PRESENTATION
The M3 display unit allows making dimensional control using 1 or 2 probes.
It is possible to make simple measurement (with one probe), or combined
measurement (with 2 probes): sums or differences. It is possible to display 1 or 2
characteristics on the screen and can make static measurement or dynamic (Max,
Min, Max-Min…)
The M3 can be connected to a PC thanks to its RS232 or USB connection.
A footswitch can be connected in order to transfer measurements.
3.2. VERSIONS
The following probes can be connected

3.3.3. Contents of the packaging
The M3 package includes :
- 1 M3 display mounted on a stand
- 1 USB cable, (length =1.8m) for power supply and/or data transfer
- 1 USB main adaptor for the display power supply. The M3 can also be powered by a
computer when connected to it with the USB.

Accessory for panel mounting.
To be installed instead of the stand.
MB-IO This M-Bus module is fitted with 8 input/outputs
isolated with opto couplers allowing to get additional
functionalities, for example: output for Go/no Go, input
for preset or start dynamic measurement... The M-Bus
modules are mounted on an aluminum profile allowing
to mount them on a standard DIN rail.
Up to 4 modules can be mounted

MB-RL The optional MB-RL module is fitted with 2
independent relays min and max, free of potential that
indicate the position of the measure according to the
part tolerances. The module is also fitted with 6 inputs
allowing to remote control the display.
This MB-RL module is wired exactly like the #24136
optional board for Monocote displays. It allows then to
replace a Monocote by a M3 without changing the
machine/plc wiring.
