Documenting Process Calibrator
Calibrating a Process Instrument
75
Test Comments
The calibrator runs tasks (custom procedures) that
are developed using a host computer and compatible
application software. A task may display a list of
proposed comments during execution. When the
comment list is displayed, select a comment to be
saved with the test results by pressing the u and d
keys followed by e.
Calibrating a Delta-Pressure Flow
Instrument
The procedure to calibrate a √ instrument is the
same as for other instruments, as just described,
with the following differences:
•
Source square-root is automatically enabled
after the
As Found calibration template is
complete.
•
Measure/Source displays are in engineering
units.
•
The measurement percentage is automatically
corrected for the transmitter’s square-root
response, and is used to compute instrument
errors.
You select the √ instrument procedure in a menu
after you press the
As Found softkey.
