Martel MC1210 Reference Manual page 24

To avoid mechanically damaging the pressure module, never apply more than 10 ft-lb. of
torque between the pressure module fittings, or between the fittings an the body of the module.
To avoid damaging the pressure module from overpressure, never apply pressure above the
rated maximum printed on the module.
To avoid damaging the pressure module from corrosion, use it only with specified materials.
Refer to the pressure module documentation for material compatibility.
To measure pressure, follow these steps:
1. Connect the pressure module to the calibrator as shown in Figure 18.
The calibrator can measure pressure on both the upper and the lower display. This makes it
possible to measure pressure in two different units at the same time.
Note: Make sure the calibrator is on before you plug in the pressure module.
2. Switch to either upper or lower display from the Main Menu.
3. Select [PRESSURE] from the primary parameters.
4. Select the desired measuring unit.
5. Zero the pressure module. The zero function on the calibrator can be found in the pressure
zeroing menu.
Note: On high pressure modules engineering units normally associated with low pressure
ranges such as, inH
high pressure module attached will cause the display to read "----".
