may be used in series when a higher output voltage
is required in the constant voltage mode of opera-
t ion or when greater voltage compliance is required
in the constant current mode of operation. Auto-
Series operation permits one-knob control of the
total output voltage from a "master" supply.
d. Auto-Parallel Operation. The power sup-
ply may be operated in parallel with a similar unit
when greater output current capability is required.
Auto-Parallel operation permits one-knob control of
the total output current from a "master" supply.
e. Auto-Tracking.
used as a "master" supply controlling one or more
"slave" supplies furnishing various voltages for a
system.

1-9 OPTIONS
1-10 Options are customer-requested factory mod-
ifications of a standard instrument. The following
options are available for the instrument covered by
this manual. Where necessary, detailed coverage
of the options is included throughout the manual.
Option No.
005 50Hz Regulator Realignment: Stand-
ard instruments are designed for 57 to
63 Hz operation. Option 005 (factory
realignment) is necessary when the
instrument is to be operated from a
50Hz ac source. The option consists
of changing a resistor in the preregu -
lator circuit and adjusting the prereg-
ulator tracking.
007 Ten-Turn Output Voltage Control:
A single control that replaces the
coarse voltage control and allows
greater resolution in setting the out-
put voltage.
008 Ten-Turn Output Current Control:
A single control that replaces the
coarse current control and allows
greater resolution in setting the out-
put current.
009 Ten-Turn Output Voltage and Current
Controls: Options 007 and 008 on the
same instrument.
010 Chassis Slides: Enables convenient
access to power supply interior for
maintenance purposes.
013 Three Digit Graduated Decadial
Voltage Control: A single control that
replaces the coarse voltage control
and allows accurate resetting of the
output voltage.
The power supply may be
Description
Option No.
014 Three Digit Graduated Decadial Cur-
rent Control: A single control that
replaces the coarse current control
and allows accurate resetting of the
output current.
Rewire for 115Vac Input (6260B only):
Consists of replacing the input power
transformer and circuit breaker, and
reconnecting the bias transformer, RFI
choke, and fans for 115Vac operation.
020 Voltage Programming Adjustment:
Two rear panel mounted, screwdriver-
adjustable controls that allow accu-
rately setting the zero volt output and
the constant voltage programming co-
efficient.
021
Current Programming Adjustment:
Two rear panel mounted, screwdriver-
adjustable controls that allow accu-
rately setting the zero current output
and the constant current programming
coefficient.
022 Voltage and Current Programming
Adjustments: Options 020 and 021 on
the same instrument.
Rewire for 115Vac Input (6259B,
6261B, and 6268B only): Consists of
replacing the line circuit breaker, and
reconnecting the input power transfor-
mer, bias transformer, RF I choke, and
fans for 115Vac operation.
027 Rewire for 208Vac Input: Consists
of reconnecting the input power trans-
former and bias transformer for 208V
ac operation.
1-11 lNSTRUMENT/MANUAL IDENTIFICATION
1-12 Hewlett-Packard power supplies are identified
by a two-part serial number. The first part is the
serial number prefix, a number-letter combination
that denotes the date of a significant design change
and the country of manufacture. The first two digits
indicate the year (10= 1970, 11= 1971, etc.), the
second two digits indicate the week, and the letter
"A" designates the U.S.A. as the country of manu-
facture. The second part is the power supply serial
number; a different sequential number is assigned
to each power supply, starting with 00101.
1-13 If the serial number on your instrument does
not agree with those on the title page of the manual,
Change Sheets supplied with the manual or Manual
Backdating Changes in Appendix A define the dif-
ferences between your instrument and the instru-
ment described by this manual.
