Troubleshooting
Pressure sensor is measuring pressure outside the range of +/ - 3 inches
of water column at startup. Ensure that the analyzer is sampling
atmospheric pressure and restart.
The analyzer was turned on with the probe sampling flue gas. Move the
probe to fresh air and restart the analyzer.
UNCALIBRATED SENSORS – COLO, COHigh, NO, NO2, or SO2 sensor(s)
do not have a calibration history stored on their printed circuit board.
Calibrate each of the sensors listed per Section 5. Message will indicate
which sensor(s) are in error.
7.4 Diagnostics and Status Screens
The DIAGNOSTICS menu provides information regarding the operation of
the analyzer. Information includes the following:
Time Meters - Displays the run time of the ana-
lyzer, sample pump and purge pump in hours of
operation.
Main Diagnostics - Lists the current status of the
Stack and Air Thermocouple channels, Reference
Temperature channel, Pressure channel, and
Battery.
O2 Sensor Life - Displays the approximate
remaining life of the Oxygen sensor.
Smart Sensors - Displays the current status of all the smart gas sensors
installed.
Fresh Air Diagnostics - Fresh air diagnostics will cycle the instrument
through the 60 second warm-up to check on the status of all sensors. The
probe must be in fresh air to perform a valid check.
Access the Diagnostic menu as follows:
1. Display the MAIN MENU by pressing the
MENU (F2) button. If necessary, press ESC until
MENU appears above F2.
2. Use the buttons to highlight DIAGNOSTICS
