6. Adjust the power supply to produce a voltage equal to top scale (from step 3)
on the Gap bar graph display. Verify that the Gap bar graph display and
Current Value Box is reading ±1 % of top scale. If the recorder output is
configured, refer to Section 5.1.10 (Verify Recorder Outputs) for steps to
verify recorder output.
7. Adjust the power supply to produce a voltage equal to bottom scale (from
step 3) on the Gap bar graph display. Verify that the Gap bar graph display
and Current Value Box is reading ±1 % of bottom scale. If the recorder
output is configured, refer to Section 5.1.10 (Verify Recorder Outputs) for
steps to verify recorder output.
8. 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).
9. 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.
10. Repeat steps 1 through 9 for all configured channels.
1X Amplitude (1X Ampl)
Note
The Keyphasor must be triggering and have a valid rpm value to check this
parameter.
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 5.1.5.1
(Test Equipment and Software Setup - Radial Vibration).
3. Calculate the full-scale voltage according to the equation and examples
shown below. Adjust the function generator amplitude to the calculated
voltage.
Full Scale Voltage = 1X Ampl Meter Top Scale X Transducer Scale Factor
Note
Use the Transducer Scale Factor displayed in the Scale Factor Box on the
Verification Screen.
