TROUBLESHOOTING

11.1 OVERVIEW

The analyzer continuously monitors itself and the sensor(s) for problems. When the analyzer identifies a problem, the word warning or fault appears intermittently in the lower line of the main display. When the fault or warning message appears, press the DIAG (diagnostic) key for more information. See Section 11.2.

A warning means the instrument or sensor is usable, but steps should be taken as soon as possible to correct the condition causing the warning.

A fault means the measurement is seriously in error and is not to be trusted. A fault condition might also mean that the analyzer has failed. Fault conditions must be corrected immediately. When a fault occurs the analog output goes to 22.00 mA or to the value programmed in Section 7.3.2.

The analyzer also displays warning messages if a calibration is seriously in error. For more information see Section 11.3.
