Check that the cable connections are not loose.
The dc power source must have a true range of 10.8 to 30.8 Vdc. At the minimum voltage of 10.8 Vdc, the dc power source must be able to supply approximately
8.7 amps for a two-channel analyzer and 12.2 amps for a four-channel analyzer. The voltage loss through an automotive cigarette lighter system can cause the dc voltage to go below 10.8 Vdc.
If the analyzer operates intermittently on dc power
The analyzer powers down when operating on dc power if no measurement has been made within 30 minutes.
Check that the dc power source can supply the required power.
Preparing the Analyzer for Use

GCheck that power transients are not causing the dc voltage to go below 10.8 Vdc.

GThe dc voltage provided by an automobile is susceptible to power transients. For example, power transients may occur when lights or fans turn on or off, when power door locks engage or disengage, and when windshield wipers operate. If the dc supply voltage falls below 10.8 V, the analyzer automatically turns off. However, the analyzer is not affected by power transients that occur within the range of 10.8 to 30.8 Vdc.

Check that the cable connections are not loose.

GObtain Agilent service, if necessary. See ‘’Need Assistance?’’ at the end of this guide.
