7.5.2 Input Calibration Procedures Description
The input calibration process consists of the following three parts:
Correcting the input at zero pressure.
Correcting the input LRV.
Correcting the input URV.
For the input calibration procedure, current loop component tolerances and values are
not critical if they support reliable communication between the Transmitter and the MC Toolkit.
However, the
Transmitter must be level
, because the meter body contains fluids that can
affect zero sensing. For leveling proceures. Refer to the
ST 700 SmartLine
Transmitter User’s
Manual
, Document # 34-ST-25-44,
Mounting Transmitters with Small Absolutge
or
Differential
Pressure Spans
for information on Transmitter leveling.
For the input calibration procedures, connect the test setup illustrated in. Either voltage mode
(Voltmeter across the resistor) or current mode (Ammeter in series with the resistor) is satisfactory.
