Resistance can also be measured using this function. To do so, use the above procedure
and choose OHMS from the sensor types. This option can be used along with a table to
measure an RTD which is not programmed into the calibrator.

3.4 Measuring Pressure

Note: The MC1210 is compatible with BETA Calibrator Pressure Modules. The accessory
BPPA-100 is required for pressure measurement.
Note: Pressure is not read from modules with frequency or pulse train mode enabled.
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 "----".
To avoid a violent release of pressure in a pressurized system, shut off the valve and slowly
bleed off the pressure before you attach the pressure module to the pressure line.
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.

Choose 2, 3, or 4-wire connection [2W, 3W, 4W]. (4-wire allows for the most precise
measurement)
