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 4 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 20 in Fix 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.
i. Click UnFix mA.
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.
