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.
