Measuring Voltage
The voltage output of a transmitter can be measured using the upper display.
To make the desired measurements, follow the principle of navigating through the
functions described in the guidelines in section 4.2 and proceed as follows
:
1. Select “Voltage” from the Upper Mode list.
2. Select the primary parameters to be measured and accept the selections.
3. Connect the leads to the isolated inputs of the calibrator, as shown in Figure 13.

Measuring Pressure
Warning
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.
Caution…
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 the principle of navigating through the functions described
in the guidelines in section 4.2 and proceed as follows
:
1. Connect the pressure module (JOFRA APM) to the ASC-400 calibrator, as shown in
Figure 15.
The calibrator can measure pressure on both the upper and the lower display. This
makes it possible to display the pressure value in two different pressure units at the
same time.
2. Select either the upper or lower display to work from.
3. Select “Pressure” from the Upper or Lower Mode list.
4. Select the desired measuring unit from the Units list
