11. Disconnect the test equipment and reconnect the PWR / B, COM, and SIG /
A (PWR, COM / A, and SIG / B for TMR I/O) field wiring to the channel
terminals on the I/O module. Verify that the OK LED comes on and the OK
relay energizes. Press the RESET switch on the Rack Interface Module
(RIM) to reset the OK LED.
12. Repeat steps 1 through 11 for all configured channels.
5.1.8.3
Verify Channel Values - Velocity
The general approach for testing these parameters is to simulate the velocity
signal with a function generator and power supply. The channel values are
verified by varying the output from the test equipment and observing that the
correct results are reported in the Verification screen on the test computer.
Note
These parameters have an accuracy specification of ±1 % of full-scale.

1. Disconnect PWR / B, COM, and SIG / A (PWR, COM / A, and SIG / B for
TMR I/O) field wiring from the channel terminals on the I/O module.
2. Connect test equipment and run software as described in Section 5.1.8.1
(Test Equipment and Software Setup - Velocity).
3. Calculate the verification frequency using the formulas in Section5.1.8.5,
page 160. Adjust the function generator frequency to the calculated value.
4. Calculate the full-scale voltage using the procedure in Section 5.1.8.6, page
160. Adjust the function generator (sinewave) amplitude to the calculated
value.
5. Verify that the Direct bar graph display and the Current Value Box is reading
±1 % of full-scale. If the recorder output is configured, refer to Section 5.1.10
(Verify Recorder Outputs) for steps to verify the recorder output).
6. If the reading does not meet specifications, check that the input signal is
correct. If the monitor still does not meet specifications or fails any other part
of this test, go to Section 5.1.11 (If a Channel Fails a Verification Test).
7. Disconnect the test equipment and reconnect the PWR / B, COM, and SIG /
A (PWR, COM / A, and SIG / B for TMR I/O) field wiring to the channel
terminals on the I/O module. Verify that the OK LED comes on and the OK
relay energizes. Press the RESET switch on the Rack Interface Module
(RIM) to reset the OK LED.
8. Repeat steps 1 through 7 for all configured channels.
