Example 1:
Peak to Peak Meter Top Scale = 10 mil
Transducer Scale Factor = 200 mV/mil
Full Scale
= (10

= 2.000 Vpp
For Vrms input:
Vrms
= (0.707/2)

(Vpp), for a sinewave input
= (0.707/2)

4. Adjust the function generator amplitude for the calculated full scale. Verify
that the pp 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 recorder outputs.
5. 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).
6. Disconnect the test equipment and reconnect the PWR, COM, and SIG 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.
7. Repeat steps 1 through 6 for all configured channels.

1. Disconnect PWR, COM, and SIG field wiring from the channel terminals on
the I/O module.
2. Connect test equipment and run software as described in section 5.1.7.1
(Test Equipment and Software Setup - Eccentricity).
