mA I/O

Calibrating 4 mA Output

1. Connect the mA receiving device to the HydroRanger 200.

2. Put the HydroRanger 200 into PROGRAM mode.

3. Set P911–mA Output Value to 4.0.

4. View the mA level on the receiving device.

5. If there is a discrepancy, use P214–4 mA Output Trim to correct the value.

Press MODE and then the ARROWs to increase or decrease the trim.

6. Repeat until the mA level on the receiving device equals 4.0 mA.

The unit is now calibrated for 4 mA for the receiving device.

Calibrating 20 mA Output

1. Connect the mA receiving device to the HydroRanger 200.

2. Put the HydroRanger 200 into PROGRAM mode.

3. Set P911–mA Output Value to 20.0.

4. View the mA level on the receiving device.

5. If there is a discrepancy, use P215–20 mA Output Trim to correct the value.

Press MODE

and then the ARROWs to increase or decrease the trim.

6. Repeat until the mA level on the receiving device equals 20.0.

The unit is now calibrated for 20 mA for the receiving device.

Verifying the mA Range

Checks that the external device can track the entire 4 to 20 mA range sent by the

HydroRanger 200.

1. Use P920 to put the HydroRanger 200 into Simulation mode (see page79).

2. Run the simulation through one complete fill / empty cycle.

3. View P911–mA Output Value to verify that it tracks to the simulation.

4. View the mA value reported on the external equipment to verify that it also tracks to

the simulation.
