Line voltage selection
The operating voltage of the instrument is internally select-
able. Refer to Section 7 for the procedure to change or verify
the line voltage setting.
Line frequency
The Model 6512 may be operated from either 50 or 60Hz
power sources.
IEEE-488 primary address
If the Model 6512 is to be programmed over the IEEE-488
bus, it must be set to the correct primary address. The prima-
ry address is set to 27 at the factory, but it may be pro-
grammed from the front panel, as described in Section 3.
1.8.2 Quick start procedure
The Model 6512 Programmable Electrometer is a highly so-
phisticated instrument with many capabilities. Although
there are a number of complex aspects about the instrument,
you can use the following basic procedure to get your instru-
ment up and running quickly. For more detailed information,
you should consult the appropriate section of the manual.
Complete, detailed operation concerning Model 6512 front
panel operation may be found in Section 2. If you wish to
control these functions over the IEEE-488 bus, consult Sec-
tion 3.
1. Carefully unpack your instrument, as described in para-
graph 1.7.
2. Locate the power cord, and plug it into the rear panel
power jack. Plug the other end of the line cord into an
appropriate power source that uses a grounded outlet.
See Section 2 for more complete information.
3. Connect a suitable triaxial cable to the rear panel INPUT
jack. (See paragraph 1.9 below for recommended triax-
ial cables.) Make sure the rear panel V,
Ω/
GUARD
switch is in the OFF position.
4. Press in on the front panel POWER switch to turn on the
power. The instrument will power up the auto-range
volts mode with zero check enabled.
5. Connect the input cable to the signal source to be mea-
sured. Remember that the Model 6512 measures DC
voltages up to 200V.
6. Disable zero check to make a measurement.
7. Take the reading from the display.
8. To change to a different measuring function, simply
press the desired function button. For example, to mea-
sure current, simply press the AMPS button.

Accessories
The following accessories are available for use with the
Model 6512.
INPUT cables
The triaxial cables listed below are recommended for mak-
ing connections to the Model 6512 INPUT jack.
Model 237-ALG-2 Triax Cable—2m (6 ft.) of low-noise tri-
ax cable (SC-22) terminated with a 3-slot male triax connec-
tor on one end, and three alligator clips on the other end.
(This cable is supplied with the Model 6512.)
Model 7078-TRX-3 Triax Cable—A low-noise triax cable
0.9m (3 ft.) in length, terminated at both ends with 3-slot
male triax connectors. Also available in 3m (10 ft.) and 6m
(20 ft.) versions (Models 7078-TRX-10 and 7078-TRX-20
respectively).
SC-22 Triax Cable—Unterminated triax cable available in
custom lengths. Use with appropriate triax connector (such
as CS-631 described below) to construct complete cables.
IEEE-488 cables
Model 7007 IEEE-488 Cables—The Model 7007 cables are
shielded cables designed to connect the Model 6512 to the
IEEE-488 bus and are available in two similar versions. The
Model 7007-1 is 1m (3.3 ft.) in length, while the Model
7007-2 is 2m (6.6 ft.) long. Each cable is terminated with a
shielded IEEE-488 connector on each end, and each connec-
tor has two metric screws.
Model 7008 IEEE-488 Cables—The Model 7008 cables are
similar IEEE-488 cables available in three lengths. The
Model 7003-3 is 0.9m (3 ft.) in length, while the Models
7008-6 and Model 7008-13 are 1.8m (6 ft.) and 4m (13 ft.)
in length respectively. Each cable is terminated with an
IEEE-488 connector on each end, and each connector has
two metric screws.
