To connect the analyzer to a dc power source

To connect the analyzer to a dc power source
In applications requiring a portable dc power source, use a properly protected dc
power system. The dc system should contain a deep cycle battery rather than a
standard automobile battery. A standard automobile battery will fail prematurely if
repeatedly discharged. Also, select a battery that provides the best compromise
between operation time and portability.
1
Set the analyzer's power switch to off (
2
Set the analyzer's POWER SELECT switch to the DC position.
The switch is in the DC position when in the ''out'' position.
3
Connect the dc power cable to the dc power source.
Using the dc power cable (HP 35250A), attach the black cable to the common terminal
and the red cable to the positive terminal of the dc power source. Using the dc power
cable with cigarette lighter adapter (HP 35251A), plug the cigarette lighter adapter
into an automotive cigarette lighter receptacle.
4
Connect the analyzer's ground terminal to the same reference potential as the common
terminal of the dc power source.
Using a wire, connect the analyzer's GROUND terminal to the common terminal of
the dc source. If you are using the dc power cable with cigarette lighter adapter,
connect the GROUND terminal to the automobile chassis.
5
Plug the dc power cable into the analyzer's DC POWER receptacle. Make sure to
align the red dot on the plug with the red dot on the receptacle.
