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.
