3.3.5. Connectors
3.3.5.1. Version for inductive probes
Note: Metro provides different version for M3 for inductive probes : for Tesa
compatible probes, for Mahr, for Metro or for Marposs. Each of these probes has the
same DIN-5 connector but is different internally. It is therefore necessary to use the
adapted probe depending on your product reference.
You can contact Metro or distributors for any advice about this point.
To connect M-BUS
modules (optional)

3.3.5.2. Version for incremental probes and encoders
Important Note : 2 versions of this unit are available. For sinewave 11µA and 1Vpp
probes (ref 13020), and for TTL probes (ref 13000).
Please make sure that you are using the right version of M3 depending on the probe
you use.
The TTL version allows to connect the Magnescale DK and Mitutoyo LG gages with a
cable adapter.
It is possible to connect rotary encoders from different brands. You can contact Metro
for any question about this subject.

3.3.7. MINI-USB connector
The mini-USB connector has 2 functions
1. Power supply through a wall mounted transformer. This transformer supplies a
regulated 5V/1A DC voltage.
2. Measurement transmission. If you connect your M3 to a PC, the PC will detect
and install automatically the M3 as a standard USB keyboard with the standard
drivers of your operating system (Windows, Mac OS etc..). When you will send
the measurement, the value will be written on your PC screen where your
cursor is, in the same way as it would have been typed with a keyboard.
Message that appears when the M1/M3 has been correctly installed:
M3
Page 16
3.3.8. The 24VDC connector
It is advised to use this power supply when the M3 is panel mounted.
Using this power supply instead of the mini-USB will deactivate the ON-OFF switch.
Therefore, when the M3 is powered, it will start automatically.
3.3.9. The USB stick connector
This connector allows to connect USB sticks and USB bar code readers (see chapter
12). It is possible to connect both at the same time using a USB hub.
It is possible to save measurements on a CSV file.
In this case the display must be set the following way:
Configuration Transfer USB key
Then once the user either press on the « PRINT » button of the measuring screen or
on the footswitch, one line will be added on the CSV file. (a « output.csv » file is
created when the operator transfers the data for the first time).
When the USB stick has been correctly detected, a USB logo will appear on top bar.
If the USB stick is not connected when the operator transfers the measurement, an
error message will pop up.
USB sticks with partitions are not supported.
3.3.10. The footswitch connector
This connector is used to connect the Metro footswitch ref 18020.
This is a JACK MONO 3.5mm (dry contact)
M3
Page 17
The footswitch can then be used for several functions: please refer yourself to the
chapter 5.4 for further information.
- Transfert the measurement
- Preset
- Start a dynamic measurement
- Zero
- Change the displayed part reference
- Hold (freezes the display) In this case, the button “CLEAR” in the measuring
screen becomes yellow:
- Screenshot : require to have a footswitch connected + a USB stick inserted. It
creates a BMP file (screenshot) in the USB stick.
4. GRAPHICAL INTERFACE
The graphical interface of your M3 has been designed to be easy to use and intuitive.
This section gives you a preview of the different screens and commands available
4.1. 2 MAIN PARTS
The graphical interface of your M3 is divided in 2 main parts:
1. A part that allows configuring the device and the measure. It consists of an
icon desktop with a few windows.
M3

The second part (measuring screen) is called by pressing the button
2. This part allows to see the measurement result and to use them. The M3
starts on this screen. For reaching the configuration screens, press on the
button

4.2. GENERALITIES
The following information can be seen on the upper part of the screen.
Advanced functions:
It is possible to enter a characteristic name, either with an RS232 command, or by
scanning a QR code.
After this, the characteristic name is written instead of P1 : C(1).
