Do not perform power supply check if all other parameters
are within tolerance.
NOTE
In the following procedure all voltages are measured with
respect to circuit common (1). Circuit common is available at
any point on inner chassis.
a. Performance Check
(1) Set TI for output of 1.000000 mV at 1 kHz.
(2) Connect ac/dc voltmeter (A1) between A8TP3 (fig. 2) and circuit common,
using cable and adapter (B6 and B2). If ac/dc voltmeter does not indicate between -69.5
and -70.5 V dc, perform b below.
(3) Repeat technique of (1) and (2) above for settings and indications listed in
table 10. If an
out-of-tolerance condition is
indicated, perform
specified adjustment.
b. Adjustments. Adjust A8R30
(fig. 2) to obtain an
ac/dc voltmeter indication of
-70.00 V dc (R).
