7. Equipment Setup
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions. REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
NOTE
Verify the proper CAL FACTORS are loaded for the
measuring receiver's sensor module.
NOTE
Due to TI recall of previous setups, it may be necessary to press
a multiple choice pushbutton more than one time to obtain the
needed parameter.
a. Check RAM battery by performing the following:
(1) Remove A2BT1.
(2) Using multimeter, check A2BT1.
(3) If multimeter
indication
is
<2.8
V
dc,
replace
A2BT1
with
NSN
6135-01-320-4815.
(4) If multimeter indication is 2.8 V dc battery replacement is not required.
b. Connect TI to autotransformer.
c. Connect autotransformer to a 115 V ac source and adjust for a 115 V output.
d. Set POWER switch to ON and allow 25 minutes for TI to warm-up and stabilize.
e. Press TI CALIBRATE key. TI will display CALIBRATING. (After approximately
20 minutes, TI will display CALIBRATED).
f. Press pushbuttons and verify display indications as listed in (1) through (11) below:
(1) RESET indicates reset (V1.02).
(2) FREQUENCY indicates FREQ 1 kHz.
(3) AMPLITUDE indicates AMPL 5 VPP.
(4) DISPLAY indicates INTENSITY 16.
(5) SYMMETRY indicates SYMM 50 PCT.
(6) PHASE indicates PHASE 0 DEG.
(7) OFFSET indicates DCOFF 0 VDC.
(8) MODULATION START/STOP indicates START 2 HZ.
(9) MODULATION START/STOP indicates STOP 2 KHZ.
(10) MODULATION TIME indicates SWPTIME 1 SEC.
(11) MODULATION TIME indicates SWPRATE 1 HZ.
