1After
this check, and only if dc voltage divider is supplied with TI, set calibrator to 9.0 V. Record TI
indication for use in (9) below.
NOTE
Perform (6) through (9) below only if dc voltage divider is
supplied with TI.
(6) Set the RANGE switch to RX100 10V.
(7) Connect dc voltage divider to DC probe. Connect dc voltage divider and
COMMON lead together and adjust ZERO ADJ for 0 meter indication.
(8) Connect dc voltage divider and COMMON lead to calibrator.
(9) Adjust calibrator for TI indication recorded in table 3. Calibrator will indicate
between 855.0 and 945.0 V.
b. Adjustments
(1) Set calibrator to 1.000 V.
(2) Adjust R32 CAL DC (fig. 1) for a 1 V indication on TI (R).
Figure 1. Adjustment locations - rear view.
9. Ac Voltage
a. Performance Check
(1) Set SELECTOR switch to AC and RANGE switch to RX1 1V.
