(14)
Set circuit breaker switch (CB1) to the ON position, and adjust DC VARIABLE POWER SUPPLY 0-32 VDC
control (T5) to provide a 10 volt indication on the external DC voltmeter.
(15)
Change the external DC voltmeter lead connections to the calibration jacks associated with DC
VOLTMETER OUTPUT VOLTAGE meter (M2), and verify that both the external DC voltmeter and the DC VOLTMETER
OUTPUT VOLTAGE meter indicate 10 volts.
(16)
Set circuit breaker switch (CB1) to the OFF position.
(17)
Connect the external DC voltmeter to the DC VARIABLE VOLTS OUTPUT binding posts, observing
polarity.
(18)
Connect a test lead from the positive (red) DC VARIABLE VOLTS OUTPUT binding post to the
REGULATOR G+ binding post, and connect a second test lead from the negative (black) DC VARIABLE VOLTS
OUTPUT binding post to the REGULATOR G-binding post.
(19)
Set DC VOLTMETER OUTPUT VOLTAGE SELECT switch (S11) to the RECT GEN position.
(20)
Set circuit breaker switch (CB1) to the ON position, and adjust DC VARIABLE POWER SUPPLY 0-32 VDC
control (T5) to provide a 10 volt indication on the external DC voltmeter.
(21)
Switch the connecting leads of the external DC voltmeter to the calibration jacks associated with DC
VOLTMETER OUTPUT VOLTAGE meter (M2), and check to see that both the external DC voltmeter and the DC
VOLTMETER OUTPUT VOLTS meter indicate 10 volts.
(22)
Set circuit breaker switch (CB1) to the OFF position.
(23)
Connect the external DC voltmeter to the DC VARIABLE VOLTS OUTPUT binding posts, observing
polarity.
(24)
Connect a test lead from the positive (red) DC VARIABLE VOLTS OUTPUT binding post to the positive
(red) EXTERNAL D.C. VOLTAGE INPUT binding post, and connect a second test lead from the negative (black) DC
VARIABLE VOLTS OUTPUT binding post to the negative (black) EXTERNAL D.C. VOLTAGE INPUT binding post.
(25)
Set DC VOLTMETER OUTPUT VOLTAGE SELECT switch (S11) to the EXT position.
(26)
Set circuit breaker switch (CB1) to the ON position and adjust DC VARIABLE POWER SUPPLY 0-32
control (T5) to provide a 10 volt indication on the external DC voltmeter.
(27)
Change the external DC voltmeter connections to the calibration jacks associated with DC VOLTMETER
OUTPUT VOLTAGE meter (M2), and check to see that both the external DC voltmeter and the DC VOLTMETER
OUTPUT VOLTAGE meter indicate 10 volts.
