CAUTION
Ensure that the line voltage selector switch on the
back panel is set to match your line voltage. Failure
to do so could result in damage to the instrument.
Note: For models 8524 and 8526, the line voltage
switch is not usable and does not allow for
220VAC operation. Do not connect them directly
into a 220V line. For 220V operation, please order
model 8524-220V or 8526-220V.
Connect an appropriate IEC power cord to the DC Load and plug the power cord into an AC power
outlet. Ensure that nothing is connected to the INPUT terminals. Turn the instrument on by pushing
the Power button in. The instrument should display
SYSTEM SELFTEST , then display
0.00V 0.000A . A small annunciator will display OFF in the upper left corner of the display. If you
do not see this display, please consult the In case of trouble chapter.
The following test will verify the DC Load can operate properly in constant current mode. Press the
I-set button (you may have to press it twice) and use the numeric keypad to set the current to 0.1 A.
To do this, press . (the decimal point), 1, Enter. Alternatively, you can adjust the current level with
the knob, then click the knob or press Enter.
Connect a power supply or battery to the DC Load, observing the polarity. Turn the power supply on
and set a voltage of 1 volt. On the DC Load, press the On/Off button. You should see
approximately 0.1 A of current flowing as shown by the instrument's ammeter and approximately 1
volt. The
CC annunciator should be displayed, showing that the instrument is in the constant current
mode.
The instrument's voltage display may read a bit less than the power supply's output -- this may be
due to a voltage drop in the wires connecting the power supply to the DC Load. Press the or
△ ▽
keys to see the power that is being consumed by the load.
