Calibrate Low
Correct
[31LO COR]
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.
