360 GAS ANALYZER

11. Bench Warning

An internal hardware problem has been detected. This warning may occur if the Gas

Analyzer is still warming up, in which case wait until the unit has finished warming prior

to recycling power. Repower the unit and check to see if the messages clears.

12. Communications Failure

The Tester cannot communicate with the Gas Analyzer. Check the power connection to

the Gas Analyzer. The fan should be blowing out of the front panel. Also check the

instrumentation port cable at both the Tester and the Gas Analyzer. It should be plugged

into the “Tester” port. Try to reestablish communication. If the unit displays

Communications (1) and briefly flashes Communications (2), turn off the Tester and turn

it back on.

13. Communications Error (1)

This error occurs when the Tester loses communication with the Gas Analyzer while

collecting data. This happens if the battery voltage drops below 8 volts to the Gas

Analyzer. This happens if power is supplied by the cigarette lighter and the engine is

cranked or the key is turned off. Check the Gas Analyzer to ensure that power is applied.

Try to reestablish communication first with the Tester prior to recycling power to the Gas

Analyzer.

14. Communications Error (3)

This error occurs when the Tester cannot download information into the Gas Analyzer.

This occurs if the Tester loses communication with the Gas Analyzer while collecting data

or the Gas Analyzer power drops below 8 volts.

SYMPTOMS

1. Does not operate

The Gas Analyzer fan is not blowing. Check the fuse in the Gas Analyzer power cable or

measure the source to assure that battery voltage is present. If the NOx access panel is

removed, a green blinking LED shows that the gas measurement subsystem is operating

properly.

2. Erratic gas readings

If the Gas Analyzer is reading erratic gas data, it may be improperly calibrated. <CHECK

STATUS> for possible warnings and then recalibrate the unit. If the readings are still

erratic, the unit may have an internal problem.

3. Does not read data when sampling vehicle exhaust

The ambient air solenoid may be active. If this is the case, press A! to start sampling

vehicle exhaust. The pumps must also be running to read gas data. If the unit is in standby

mode, press A# in the <DATA LIST> mode to turn the pumps on.
