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.
2. Test the frequency output(s).
Note
If the Weights & Measures application 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.
c. Click Fix FO.
d. Read the frequency signal at the receiving device and compare it to the
transmitter output.
e. Click UnFix FO.
3. Test the discrete output(s).
a. Choose Device Tools > Diagnostics > Testing > Discrete Output Test.
b. Set Fix To: to ON.
c. Verify the signal at the receiving device.
d. Set Fix To: to OFF.
e. Verify the signal at the receiving device.
