5. QUICK START
1 – Connect the air input to the air preparation unit ref Metro ACS-PNE-003. The air pressure
should be at 3 BAR (0.3Mpa) and
never exceed 4 BAR (0.4MPA). It is advised to lock the
pressure adjustment in order not to let someone change the pressure value after having
calibrated the display.
2 – Connect your air gage on the output « OUTPUT – AIR GAGE »
3 – Power the M1/M3 either with the mini USB or with the 24VDC terminal.
4 – Turn on the M1/M3 by pressing the ON-OFF switch.
5 – Calibration of the device:
 To be done the first time, and can be done or verified again periodically (wear of the
master or the gage)
 The M1/M3 requires 2 masters for the calibration. The MIN and MAX masters should
respectively correspond to the lower and upper tolerance limits of the measured part.
A – From the « SETUP » icon, write the master values according to your calibration
certificate. The display need 2 masters MIN and MAX to be used.
B – Place your MIN master in measuring position and press on the « calibration »
button. The button becomes green for a couple of seconds.
C – Repeat the step B for the MAX master.
D – You can check by placing again the MIN master. The value on the « position »
field must be at 0.0000, then by placing the MAX master, the « position » field must
indicate the dimensional difference between the 2 masters.
6 – Configuration of the part to be measured. (From the Icon « definition »)
A – Use the scroll bar to reach the 2nd screen.
B – Write the value of MIN and MAX tolerances (that should correspond to your MIN
and MAX masters). The tolerance must be written relative from the nominal value. For
example if your part has a nominal diameter of 10mm +/-0.005, you must write in the
Upper tolerance 0.005 and lower tolerance -0.005, and in the nominal field: 10.
It is then advised to use the MAX master in the case of external diameter
measurement, and to use the MIN master in the case of internal diameter
measurement (in order to have fewer positioning problems). So you need to fill the
« Master » field with the adapted value.
C – Close the window, and come back to the measuring screen by pressing the
« measure » icon.
7 – Preset
A – Place your Min or MAX master according to what you have defined in 6-B.
B – Press on the « PRESET » button. The value must change to the master value. You can
now check with the 2 masters if the values are correct.
You are now ready to measure.
