Calibrating a Pressure Transmitter
The following steps explain calibrating a pressure
transmitter.
1. Connect the Calibrator to the instrument under test
as shown in Figure 21.
2. Press
l for current (upper display). If required,
press
l again to activate loop power.
3. Press
U (lower display).
4. If necessary, press M for SOURCE mode.
5. Zero the pressure module.
6. Perform checks at 0 % and 100 % of span and
adjust the transmitter as necessary.
Note
When HART resistor mode is selected, the
250
Ω
resistor is turned on both mA channels.
