(4) Adjust R7 (3.2 V AC Range) (fig. 1) for a 3.000 V ac 0.001 V ac TI indication. (R)
(5) Press RANGE pushbutton for 320.0 V range.
(6) Set calibrator for a 300 V, 5 kHz output.
(7) Adjust C4 (320 V AC Range) (fig. 1) for a 300.0 V ac 0.1 V ac TI indication. (R)
(8) Press RANGE pushbutton for 1000 V range.
(9) Set calibrator for a 1000 V, 5 kHz output.
(10) Adjust C10 (1000 V AC Range) (fig. 1) for a 1000 V ac 1 V ac TI indication. (R)
(11) Set calibrator to STBY.
(12) Press RANGE pushbutton for 32.00 V range.
(13) Set calibrator for a 30 V, 5 kHz and OPR.
(14) Adjust C8 (32 V AC Range) (fig. 1) for a 30.00 V ac 0.01 V ac TI indication. (R)
(15) Set calibrator for a 3 V, 5 kHz output.
(16) Press RANGE pushbutton for 3.200 V range.
(17) Adjust C6 (3.2 V AC Range at 10 kHz) (fig. 1) for a 3.000 V ac 0.001 V ac TI
indication. (R)
(18) Set calibrator for a 3 V, 100 Hz output. If TI does not indicate between 2.980
and 3.020 V ac, repeat (4) through (17) above as necessary.
(19) Set calibrator to STBY and disconnect connections.
11. Resistance
a. Performance Check
NOTE
To subtract test lead resistance from the 320.0 Ω reading, short
the test lead tips together between the TI VΩ
and COM
and momentarily press the REL Ć key.
(1) Connect TI VΩ
and COM to calibrator OUTPUT HI and LO.
(2) Set function switch to Ω.
(3) Set TI and calibrator for settings listed in table 7. At each setting, use calibrator
output adjustment controls to set calibrator control display Reading equal to TI indication.
Calibrator control display Error indications will be within limits specified in table 7.
