Prerequisites
•
Follow appropriate procedures to ensure that loop testing will not interfere with
existing measurement and control loops.
12.14.1
Perform loop tests using ProLink III
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.
Procedure
1.
Test the mA Output(s).
a. Choose Device Tools > Diagnostics > Testing > mA Output 1 Test or Device Tools
> Diagnostics > Testing > mA Output 2 Test.
b. Enter

in Fix 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

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.
i. Click UnFix mA.
2.
Test the Frequency Output(s).
Note
If the Weights & Measures application with NTEP approval is enabled on the transmitter, it is
not possible to perform a loop test of the Frequency Output, even when the transmitter is
unsecured.
a. Choose Device Tools > Diagnostics > Testing > Frequency Output Test.
b. Enter the Frequency Output value in Fix to.
