b. Items of equipment used in this procedure are referenced within the text by common
name as listed in table 2.
c. Unless otherwise specified, verify the result of each test and, whenever the test
requirement is not met, take corrective action before continuing with the calibration.
Adjustments required to calibrate the TI are included in this procedure. Additional
maintenance information is contained in the manufacturers' manuals for this TI and
TM 55-6670-200-14&P.
d. Unless otherwise specified, all controls and control settings refer to the TI.
NOTE
Units having transfer equipment will use the transfer
technique. If calibration above 15,000 pounds is required, the
reference technique will be utilized. If transfer equipment is
not available, use reference technique pending availability of
transfer equipment. All TI's certified by transfer technique
will have a DA Label 163 affixed stating that each cell was
certified to 15,000 pounds only. When transfer technique is
used and TI cannot be adjusted to within tolerance, TI will be
forwarded for reference calibration and repair.
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.
a. Set voltage selector switch on TI to position which corresponds to power source being
used. Connect TI to power source.
b. If ac voltage is used, check voltage as follows:
(1) Set power switch to 115 V, 60 Hz.
(2) Operate BATTERY VOLTAGE switch on indicator panel of TI and adjust AC
VOLTAGE ADJUST control until pointer of balance meter indicates in green area of
milliammeter scale.
c. If 24 V dc is used as power source, operate BATTERY VOLTAGE switch and check
polarity. If meter indication is in yellow area, change leads and operate BATTERY
VOLTAGE switch again. If meter indication is in red area, battery voltage is either too
high or too low and should be replaced.
e. Connect all three TI cells to TI indicator using proper cables (color coded).
