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 9.
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.

Percent Error Function

The Product features a unique function which can
calculate pressure vs. milliamp error as a percentage of
the 4 mA to 20 mA loop span. The percent error mode
uses all three screens and has a unique menu structure.
It simultaneously shows pressure, mA, and percent error.
See Figure 10.
