Perform loop tests using ProLink II

Prerequisites
Before performing a loop test, configure the channels for the transmitter inputs and
outputs that will be used in your application.
Follow appropriate procedures to ensure that loop testing will not interfere with existing
measurement and control loops.
ProLink II must be running and must be connected to the transmitter.
Procedure
1.

c. At the transmitter, activate Select.
d. Scroll to and select SET OFF.
e. Verify the signal at the receiving device.
f. At the transmitter, activate Select.
If the mA output reading was slightly off at the receiving device, you can correct this
discrepancy by trimming the output.
If the mA output reading was significantly off (±200 microamps), or if at any step the
reading was faulty, verify the wiring between the transmitter and the remote device,
and try again.
If the discrete output reading is reversed, check the setting of Discrete Output Polarity.
Test the mA output(s).
a. Choose ProLink > Test > Fix Milliamp 1 or ProLink > Test > Fix Milliamp 2.
b. Enter 4 mA in Set Output To.
c. Click Fix mA.
d. Read the mA current at the receiving device and compare it to the transmitter
output.
The readings do not need to match exactly. If the values are slightly different,
you can correct the discrepancy by trimming the output.
e. Click UnFix mA.
f. Enter 20 mA in Set Output To.
g. Click Fix mA.
h. Read the mA current at the receiving device and compare it to the transmitter
output.
The readings do not need to match exactly. If the values are slightly different,
you can correct the discrepancy by trimming the output.
