Inaccurate calibration
equipment will only
degrade the performance
of the transmitter.
•
Manufacturers recommend
using precise calibration
equipment under stable,
ambient conditions for
best results.
•
Commission transmitters
at the bench so security
settings and protection
for failure modes can be
set before exposing
transmitter electronics to
factory conditions.
Connect the transmitter test hose from the calibrator to the transmitter
Connect the mA measurement jacks of the calibrator to the transmitter
Set the pressure/vacuum selection knob to the necessary function
Close the vent knob and supply metering valve
Apply pressure or vacuum from the pump by holding down the
pump button and release when the necessary pressure is reached
Correct the pressure with the fine pressure adjustment
Read the reference pressure and the current output of the transmitter
from the display
Repeat for all test points. If the measured mA signal at the test points
is found within tolerance the test is complete. If not, then adjustment
is required.
