13. Equipment Setup
WARNING
HIGH VOLTAGE is used or exposed during the performance
of-this calibration. DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
a. Remove TI from carrying case.
b. Place TI on a firm, level base and avoid large deposits of iron and magnetic fields.
14. Meter Range
a. Performance Check
(1) Connect LINE and GROUND terminals of TI together, using lead and adapters
(B4, B1, and B2).
NOTE
The meter pointer may stand anywhere over the scale until TI
is operated.
(2) Rotate generator crank cw at normal operating speed.
Meter will indicate
ZERO.
NOTE
To obtain a correct indication on TI meter, the hand-operated
generator crank must be rotated cw at normal operating speed.
The generator reaches operating speed when centrifugal clutch
begins to slip.
(3) Disconnect shorting lead from LINE and GROUND terminals and rotate
generator crank. Meter pointer will indicate infinity.
(4) Connect standard resistor (A2) between LINE and GROUND and set for 1 kΩ.
(5) Set TI RANGE switch to Ω. Rotate generator crank cw at normal operating
speed. If TI meter does not indicate between 950 and 1050, perform b below.
