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 800 SmartLine Transmitter User’s
Manual, 34-ST-25-35, “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.
