(9) TI voltage dials will indicate within 25 microvolts of value recorded in (6)
above.
(10) Adjust autotransformer output to 125 volts and wait 1 minute.
(11) Adjust TI voltage dials for a null indication on null detector.
(12) TI voltage dials will indicate within 25 microvolts of value recorded in (6)
above.
(14) Remove decade resistor from equipment setup and wait 1 minute.
(15) Adjust TI voltage dials for a null indication on null detector.
(16) TI voltage dials will indicate within 25 microvolts of value recorded in (6)
above.
(17) Turn POWER switch to STANDBY/RESET.
b. Adjustments. No adjustments can be made.
8. Zero Voltage
a. Performance Check
(1) Set dc transfer standard (A2) for (supply number 1) ∆E output and ∆E control to
000.
(2) Position TI controls as listed in (a) through (c) below:
(a) VOLTAGE RANGE switch to 1000.
(b) Voltage dials to 0000000.
(c) POWER switch to ON.
(3) Adjust ∆E control of dc transfer standard for a null indication on null detector
(A4).
(4) If ∆E control of dc transfer standard does not indicate 040 microvolts, perform
b(1) below.
NOTE
If reading is negative, reverse leads at OUTPUT of dc transfer
standard.
