Two-point Field Accuracy
Calibration Method for
DP/AP/GP transmitters
Not normally used. See Field
Calibration for Alternate
Ranges, below. Executing this
selection corrects input
pressure to be at or near the Cal
Low Point without
compromising LRV and URV
corrections. A
trial-and-error approach using
different Cal Adjust Ratio
values and repeated executions
of Cal Low Correct followed by
Cal High Correct may be
required.
The live value of the primary
pressure input is shown on this
display so the user can easily see
the result of the correction.
Note: Cal Low Correct must be
performed before Cal High
Correct, but Cal High Correct
may be repeated as
necessary.
