8.3 Analog Output Adjustment; Trimming theanalog output to match a loop meter (This functionis factory calibrated, and generally does not have to be adjusted)

1. Measure the loop current (mA dc) on the desired analog output channel.

2. Menu 4.0n.07 will force the loop current to 4.00mA. 3. Using the keypad, enter the actual loop current indicated on your device (multimeter)

4. The receiver will recalibrate the analog output to match your entered value.

1. Measure the loop current (mA dc) on the desired analog output channel.

2. Menu 4.0n.08 will force the loop current to 20.00mA.

3. Using the keypad, enter the actual loop current indicated on your device (multimeter)
