Transmitter Calibration
mA Input Function
The mA input function reads back the 4 mA to 20 mA
output from the device being calibrated. This can be done
passively. The device under test directly generates 4 mA
to 20 mA and can be read by the Product.
Pressure-to-Current Transmitter Calibration
To calibrate a pressure-to-current transmitter (P/I):
1.
Connect the Product and the pump to the transmitter.
See Figure 7.
2.
Apply pressure with the pump.
3.
Measure the current output of the transmitter.
4.
Ensure the reading is correct. If not, adjust the
transmitter as necessary.
Use low-volume tubing when possible.
