SECTION 2
GETTING STARTED
2.1 INTRODUtilON
The Model 595 can be controlled from the front panel or
over the IEEE-488 bus. This section will acquaint the user
with front panel operation. IEEE-488 bus operation is
described in Section 4.
The following paragraphs will briefly describe the front
panel buttons and their operation to help the user get
started with the Model 595. Then rear panel descriptions
and power-up information will be presented. Lastly, basic
capacitance and current measurement examples will be
discussed.
2.2 PREPARATION FOR USE
Once the instrument is unpacked, it must be connected to
an appropriate power source as described below.
2.2.1 Line Power
The Model 595 is designed to operate from lO5XW or
210~25OV power sources. A special power transformer may
be installed for 90-1lOV and 195-235V ranges. The factory
set range is marked on the rear panel of the instrument.
CAUTION
Do not attempt to operate the instrument on a
supply voltage outside the indicated range, or
instrument damage might occur.
2.2.2 Line Voltage Selection
The operating voltage of the instrument is internally select-
able. Refer to Section 8 for the procedure to change or verify
the line voltage setting.
2.2.3 Line Frequency
The Model 595 may be operated from either 50 or 6OHz
power sources. The line frequency of the instrument must
match the line frequency of the power source in order to
meet measurement noise specifications. See Section 8 for
details.
2.3 POWER UP PROCEDURE
2.3.1 Power Cord
Connect the female end of the power cord to the AC recep-
tacle on the rear panel of the instrument. Connect the male
end of the cord to a grounded AC outlet.
WARNING
The Model 595 is equipped with a 3-wire power
cord that contains a seoarate around wire and
is designed to be used'with grounded outlets.
When proper connections are made, instrument
chassis is connected to power line ground.
Failure to use a gmunded outlet may result in
personal injury or death because of electric
shock.
CAUTION
Be sure that the power line voltage agrees with
the indicated range on the rear panel of the in-
strument. Failure to observe this precaution may
result in instrument damage. If necessary, the
line voltage may be changed as described in
Section 8.
