3.4-1 Zeroing with Absolute Pressure Modules.
To zero, adjust the calibrator to read a known pressure, such as
barometric pressure.
To adjust the calibrator, follow these steps:
1.
2.
3.
The zero offset is stored for one absolute pressure module at a
time. If a new absolute module is connected this process must
be repeated.

4. Using Source Modes (Lower Display)

The calibrator can generate calibrated signals for testing and
calibrating process instruments. It can source voltages, currents,
resistances, frequencies, pulses, and the electrical output of RTD
and thermocouple temperature sensors.
