Important note
The M210 device is an electronic which puts forward its analogue output before its display (the display works as an
output copy). All metrological check has to be done thru the analogue output.
1. Before you start
•Connect the sensor to the conditioning module as per the wiring scheme.
•Ensure that the wires are correctly tightened into the terminal block.
•Connect the M210 to the 230 Vac – 50Hz supply or DC supply (depending on version).
•Wait a few moments for the display to stabilise (warm-up time).
NOTE: The standard M210 can function with 115 V –50 Hz (main supplied version) by changing an internal
jumper.

2. Analogue output
2.1 SETTING THE ZERO
•Use the front panel potentiometer (bottom right hand side) to set the output to 0 Vdc.
2.2 SETTING THE GAIN
•The gain is set using the calibration function and the gain potentiometer. The gain
potentiometer is hidden behind the front panel on the bottom right hand side, above the zero
potentiometer.
•The calibration function simulates a pressure, or force, as determined during calibration.
•To simulate the pressure (or force) press the calibration pushbutton (see section II of the
"ADJUSTMENT" section if no pushbutton is present).
•Use the gain potentiometer to obtain the calibration value on the analogue output.
•Release the pushbutton, check the zero and refine the adjustments if necessary.
•The analogue output is adjusted correctly
Now adjust the display.

3. Display
3.1 SETTING THE ZERO
•Use the front panel potentiometer (bottom left hand side) to adjust the analogue output to 0
Vdc with the sign flashing.
3.2 SETTING THE DISPLAY GAIN
•The gain is set using the calibration function and the gain potentiometer. The gain
potentiometer is hidden behind the front panel on the bottom left hand side, above the zero
potentiometer.
•The calibration function simulates a pressure, or force, as determined during calibration.
•To simulate the pressure (or force) press the calibration pushbutton (see section II of the
"ADJUSTMENT" section if no pushbutton is present).
•Use the gain potentiometer to obtain the calibration value on the display.
•Release the pushbutton, check the zero and refine the adjustments if necessary.
The M210 is ready to function

RG1 is in k.
Ve corresponds to the sensor sensitivity in mV for Full Scale.
•Example :
Pressure transducer : 1 bar.
Sensitivity : 2 mV/V.
Excitation : 10 V.
RG1 = 0.885 k.
Use the closest standard resistance value (± 1 %/50ppm/°C), in this case 887  and use the
gain potentiometer to fine tune the analogue output.

II. Calibration resistance RC1
The positions of the RC1 calibration resistor and BP are shown in the schema included in this document.
RC1 RESISTANCE DETERMINATION
•Short-circuit BP, and put a variable resistance (decade box) in place of RC1.
•Manually choose the value of RC1 which simulates approximately 80 % of full scale
•Choose the closest standard resistance value
•Mount RC1 in its place and replace BP with a pushbutton
•Note the values of the analogue outputs and the display when the test pushbutton is pressed,
these two values correspond to the calibration values.
To calibrate the measurement chain once the pushbutton is mounted, see
paragraphs I and II of "USER NOTICE".
Attention !
The RC1 calibration resistance values are measured after having adjusted the gain and
the zero of the measurement chain.
To set up the measurement chain correctly, one should:
1) Load the sensor and determine its sensitivity.
2) Calculate the value of RG1, fine adjust using the front panel potentiometers (zero unloaded
and gain loaded).
3) Determine the calibration resistance value RC1.
4) Note the calibration values obtained with the calibration
