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.
