• 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.
To perform the test:
STEP 1 STEP 2 STEP 3 STEP 4 STEP 5 STEP 6 STEP 7
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 adjustmentis required
