WARNING
Dangerous potential exists between chassis and ground.
Exercise extreme caution.
(1) Set ∆E control of dc transfer standard to 000 and adjust R6, 1000V ZERO
OUTPUT ADJUST (fig. 5 or 6) for a null indication on null detector (R).
(2) Set ∆E control of dc transfer standard to 000 and adjust R4, 100V ZERO
OUTPUT ADJUST(fig. 5 or 6) for a null indication on null detector (R).
(3) Set ∆E control of dc transfer standard to 000 and adjust R2, 10V ZERO
OUTPUT ADJUST (fig. 5 or 6) for a null indication on null detector (R).
17. Linearity (Model 332B)
a. Performance Check
(1) Set voltage divider (A7) to .1000000.
(2) Set dc transfer standard (A2) for a 1-volt mean output.
(3) Position TI controls as listed in (a) through (c) below:
(a) VOLTAGE RANGE switch to 1000.
(b) Voltage dials to 00X.0000.
(c) POWER switch to OPR.
(4) Adjust voltage divider for a null indication on null detector (A4) (within 10
microvolts). Record null detector indication.
(5) Set TI voltage dials to 010.0000.
(6) If null detector indication is not within 1 microvolt of value recorded in (4)
above, perform b(1) and (2) below.
(7) Repeat the technique of (1) through (6) above, using settings, indications, and
(8) Set POWER switch to STDBY/RESET.
NOTE
Dangerous potentials exist between chassis and ground.
Exercise extreme caution.
