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.
