DC VOLTMETER OUTPUT VOLTAGE Meter Circuit.
(1)
Set all test stand controls to the preliminary settings listed in table 2-2.
(2)
Connect an external 0-50 volt DC voltmeter to the DC VARIABLE VOLTS OUTPUT binding posts (fig 2-5),
observing polarity.
(3)
Set DC VOLTMETER OUTPUT VOLTAGE RANGE switch (S12, fig 2-4) to the X5 position, and DC
VOLTMETER OUTPUT VOLTAGE SELECT switch (S11) to the VAR position.
(4)
Set DC VARIABLE POWER SUPPLY 0-32 VDC control (T5, fig 2-7) fully counterclockwise.
(5)
Set circuit breaker switch (CB1) to the ON position.
(6)
Set D.C. VARIABLE VOLTS switch (S10) to the ON position, and adjust DC VARIABLE POWER SUPPLY
0-32 VDC control (T5) for a 5-volt indication on the external DC voltmeter.
(7)
Set DC VOLTMETER OUTPUT VOLTAGE RANGE switch (S12) to the X1 position, and verify that the
indication on DC VOLTMETER OUTPUT VOLTAGE meter (M2) agrees with that on the external DC voltmeter.
(8)
Connect the external DC voltmeter to the calibration jack associated with DC VOLTMETER OUTPUT
VOLTAGE meter (M2). Set DC VOLTMETER OUTPUT VOLTAGE RANGE switch (S12) the X2 position, and adjust DC
VARIABLE POWER SUPPLY 0-32 VDC control (T5) for a 10-volt indication on the external DC voltmeter. Verify that
DC VOLTMETER OUTPUT VOLTAGE meter (M2) also indicates 10 volts.
(9)
Set DC VOLTMETER OUTPUT VOLTAGE RANGE switch (S12) to the X5 position. Adjust DC VARIABLE
POWER SUPPLY 0-32 VDC control (T5) to provide a 20 volt indication on the external DC voltmeter. Verify that DC
VOLTMETER OUTPUT VOLTAGE meter (M2) indicates 20 volts.
(10)
Set circuit breaker switch (CB1) to the OFF position.
(11)
Connect the external DC voltmeter to the DC VARIABLE VOLTS OUTPUT binding posts, observing
polarity.
(12)
Connect a test lead from the positive (red) DC VARIABLE VOLTS OUTPUT binding post to the
REGULATOR B+ binding post (fig 2-6) and connect a second test lead from the negative (black) DC VARIABLE VOLTS
OUTPUT binding post to the REGULATOR B-binding post.
(13)
Set DC VOLTMETER OUTPUT VOLTAGE SELECT switch (S11) to the BAT POSITION.
