2. Test the Frequency Output(s).
a) Choose Menu > Service Tools > Output Simulation and select the frequency output to test.
b) Set Simulation Value to 1.
c) Start the simulation.
d) Read the frequency signal at the receiving device and compare it to the transmitter output.
e) Choose New Value.
f) Set Simulation Value to 1450.
g) Start the simulation.
h) Read the frequency signal at the receiving device and compare it to the transmitter output.
i) Choose Exit.
3. Test the Discrete Output(s).
a) Choose Menu > Service Tools > Output Simulation and select the discrete output to test.
b) Set Simulation Value to ON.
c) Start the simulation.
d) Verify the signal at the receiving device.
e) Choose New Value.
f) Set Simulation Value to OFF.
g) Start the simulation.
h) Verify the signal at the receiving device.
i) Choose Exit.
Postrequisites
• If the mA Output readings are within 20 microamps of the expected values, you can correct this
discrepancy by trimming the output.
• If the discrepancy between the mA Output readings is greater than 20 microamps, or if at any step the
reading was faulty, verify the wiring between the transmitter and the remote device, and try again.
