1If
difference exceeds this value, perform adjustment.
2Report
adjustments only if difference is greater than 100 microvolts.
3Report this adjustment if difference is greater than 30 microvolts.
(1) Adjust DECK B adjustment 1 (fig. 5) for same indication on null detector (R).
(Report only if difference is greater than 30 microvolts.)
(2) Repeat a above until no further adjustments required.
18. Linearity (Model 332B/AF)
a. Performance Check
(1) Set voltage divider (A7) to .999999X.
(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 000.X000.
(c) POWER switch to OPR.
NOTE
If null indication cannot be obtained at a 000.X000 dial setting,
adjust R1, CAL 1000V (fig. 6) to obtain a null indication.
(4) Adjust voltage divider for a null indication on null detector (A4) (within 10
microvolts). Record null detector indication.
(5) Set voltage dials to 001.0000.
