Zeroing with Absolute Pressure Modules
For zeroing, adjust the Calibrator to read a known pressure. This
can be barometric pressure, if it is accurately known, for all but
the 700PA3 module. An accurate pressure standard can also
apply a pressure within range for any Absolute Pressure Module.
Adjust the Calibrator reading as follows:
1. Press and hold
Z
.
2. Press
c
to increase or
h
to decrease the Calibrator
reading to equal the applied pressure.
3. Release
Z
to exit the zeroing procedure.
To convert measurement units to different units displayed on the
Calibrator, use the following sample conversions:
• 1 bar = 750 mm Hg (1 mm Hg = 0.0013332 bar)
• 1 psi = 2.036 in. Hg ( 1 in. Hg = 0.49115 psi).
Calibrating a P/I Transmitter
To calibrate a P/I (pressure to current) transmitter, apply a
pressure to the transmitter and measure the transmitter’s current
loop output. Connect the Calibrator to the transmitter as shown in
the figure.
