(8) Repeat steps 2 through 7 for the remaining channels 2, 3, 4, and 5.
(9) Connect jumper wire between pins A and B on the connector labeled VIB1 of cable 20090778-1.
(10)Verify that TI channel 1 bar graph and digital display indications are ZERO. Adjust the Digital Bar
graph Indicator's ZERO controls R4 as necessary. Disconnect the jumper wire.
(11)Repeat steps 9 and 10 for TI channels 2 through 5 using the following connections.

(13)Set TI FILTER switch to SENS position for all channels and adjust each channel SENS ADJ control
for an indication of 150 on each display.
(14)Set TI mode switches to VEL on each channel, range switch to 5.0 and filter switch to OUT.
(15)Connect the CEC 2700 Signal Source J2 connector pins A(+) and B(-) to pins A (+) and B (-) of
connector VIB1 on cable 20090778-1. Ensure that CEC2700 signal source is set to AUG.
(16)Maintain the CEC 2700 oscillator at a
constant output frequency (100 Hz) while changing the output
millivolt level to the values listed below.
(17)At each output level, verify that the TI vibration meter indicator and AEDATS reads within the
tolerance limits listed.
