358 GAS ANALYZER

A. TROUBLE SHOOTING: IF YOU'RE

HAVING A PROBLEM

The Gas Analyzer is a very sophisticated piece of test equipment. Occasionally problems

occur. The Gas Analyzer has extensive on-board self-diagnostics that generate warning or

error messages if a problem is detected. You may find some problems first. The most

common method of clearing errors are:

• Repowering the Tester

• Checking system status

• Zeroing

• Repowering the Gas Analyzer

• Calibrating

If the Gas Analyzer does not return to normal operation after trying all of the suggestions,

please refer to the Introduction section on Warranty and Repair information.

PXA STATUS MESSAGES

The first place to check after receiving a warning/error message is <1: CHECK STATUS>

under the <MAINTENANCE> menu. The presence of a message indicates that it is

currently active. The following list of warning/error messages describes the condition and

possible solutions.

1. Warmup in Progress

When the Gas Analyzer is first powered on, the gas measurement system requires 5 to 15

minutes to warm up and stabilize. When this flag is active, the Bench Warning message

may also appear. If the system does not clear the Warmup in Progress flag after 20

minutes, recycle power. If, after 10 minutes more, the unit does not clear the Warmup in

Progress flag, then an internal problem exists.

2. Zero Warning

The Zero Warning message indicates that at least one of the gas's zero levels changed by

more than 5% of the last zero level. Performing another zeroing of the Gas Analyzer

should remove this message. The unit may not be completely warmed up internally. The

unit is sensitive to temperature. The longer the unit is on, the more accurate and stable the

Gas Analyzer performs.

3. Zero Required

The Zero Required message indicates that the Gas Analyzer has determined a need to zero

the unit. Zeroing the unit provides a reference condition to measure the vehicle exhaust

against. The Gas Analyzer normally needs to be zeroed every 20 to 30 minutes.

4. O2S Zero Warning

The Oxygen Zero Warning message indicates that the sensor connector was still attached

during the O2S Zero procedure, or the oxygen sensor hardware is not working properly.

Re-run the O2S Zero procedure under the <MAINTENANCE> menu. If the message

returns, then an internal problem exists.
