(5) Set VOLTAGE RANGE switch to 100.
(6) Repeat (3) above.
(7) If ∆E control of dc transfer standard does not indicate, 0 20 microvolts, perform
b(2) below.
(8) Set VOLTAGE RANGE switch to 10.
(9) Repeat (3) above.
(10) If ∆E control of dc transfer standard does not indicate 0 10 microvolts, perform
b(3) below.
(11) Set POWER switch to STANDBY/RESET.
b. Adjustments
WARNING
Dangerous potentials exist between chassis and ground.
Exercise extreme caution.
(1) Set ∆E control of dc transfer standard to 000 and adjust R112 (fig. 3) for a null
indication on null detector (R).
(2) Set ∆E control of dc transfer standard to 000 and adjust R110 (fig. 3) for a null
indication on null detector (R).
(3) Set ∆E control of dc transfer standard to 000 and adjust R108 (fig. 3) for a null
indication on null detector (R).
9. Linearity
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 ON.
