30. Dc Voltage
a. Performance Check
(1) Connect leads between TI GUARD and LO terminals and between LO and
HI terminals.
(2) Press FUNCTION DCV and RANGE 10 V pushbuttons and release FAST
pushbutton. Measuring system will indicate 0.0000 (0.0003).
(3) Press RANGE 100 V pushbutton. Measuring system will indicate 00.000 (00.003).
(4) Press RANGE 1000 V pushbutton. Measuring system will indicate 000.00 (000.30).
(5) Press RANGE 10 V pushbutton and remove jumper from HI and LO terminals.
CAUTION
Do not exceed maximum voltages indicated on front panel of TI.
(6) Connect calibrator to TI HI and LO terminals.
(7) Set calibrator output to +9.0000 V dc. If TI does not indicate between 8.9970
and 9.0030, perform b (1) below.
(8) Set calibrator output to -9.0000 V dc. If TI does not indicate between -8.9970
and 9.0030 V dc, perform b (2) below.
(9) Press RANGE 100V pushbutton.
(10) Set calibrator output to +90.000 V dc. If TI does not indicate between +89.970
and +90.030 V dc, perform b (3) below.
(11) Press RANGE 1000V pushbutton.
(12) Set calibrator output to +900.000 V dc. If TI does not indicate between +898.83
and +901.17 V dc, perform b (4) below.
b. Adjustments
(1) Adjust +V ADJ R24 (rear panel) to obtain +9.0000 V dc indication on measuring
system (R).
(2) Adjust -V ADJ R1 (rear panel) to obtain -9.0000 V dc indication on measuring
system (R).
(3) Adjust A2R18 (fig. 3) to obtain indication of +90.000 V dc on measuring system (R).
(4) Adjust A2R24 (fig. 3) to obtain indication of +900.000 V dc on measuring system (R).
31. Ac Voltage
a. Performance Check
(1) Connect lead between TI HI and LO terminals.
(2) Press FUNCTION ACV pushbutton and RANGE pushbuttons as listed in table
(3) Remove lead from HI and LO terminals.
