Control Settings
Set the controls as given under Preliminary Control
Settings.
1. Adjust —50 Volt Power Supply
a. Set the INTENSITY control fully counterclockwise.
b. Connect the precision DC voltmeter between TP—50
{see Fig. 2-1A) and chassis ground.
c, CHECK—Meter reading; —50 volts 0.1 volt.
d. ADJUST— -—50 volts adjustment R881 (see Fig.
2-1B) for a meter reading of exactly —50 volts.
e. INTERACTION—Change in setting of R881 may
affect operation of all circuits within the 7613.
2. Check Remaining Power-Supply Voltages
a. CHECK—Table 2-1 lists the low-voltage power
supplies in this instrument. Check each supply with the
precision DC voltmeter for output voltage within the given
tolerance (connect meter ground lead to chassis ground).
Power supply test points are shown in Fig. 2-1A.
b. Disconnect the precision DC voltmeter.
NOTE
Ripple and regulation of the individual power
supplies can be checked using the procedure given
under Troubleshooting Techniques in Section 4.
