7.3 Error Messages Displayed After Warm-Up

If there were problems detected during warm-up, error messages that describe the nature of the problems are displayed immediately following the analyzer’s 60 second warm-up period.

If problems were detected, the analyzer will not automatically switch to the Combustion Test HOLD screen after warm-up. The analyzer, however, can still be used to perform any test that does not depend on the sensor that is in error. Press the RUN button to manually display the Combustion Test HOLD screen, and then continue using the analyzer.

The following is a list of the error messages that may appear following warm-up and their suggested remedies:

Low Battery – Battery voltage is low. Only several minutes of operating time remain. Replace or charge batteries per Section 3.2.

O2 No Sensor – Oxygen sensor not installed, or has become unplugged from its electrical connector. Install oxygen sensor per Figure 6-2 on Page 6-3.

O2 BAD Sensor – The oxygen sensor’s output is below 24 mV, signifying that the sensor is depleted and needs replaced. Refer to Section 6.3.

No Smart Sensors – No gas sensors are installed. Install sensors per Section 6.3.

Pressure Overrange – Pressure sensor measured a pressure that was outside the range of ±3 inwc during warm-up. Ensure that probe tip is open to the atmosphere during warm-up.

Ts Error – The probe’s thermocouple is not connected to the analyzer’s T- STACK connector.

Ts Overrange – The temperature measured during warm-up was outside the range of –4 to 2,192 °F (–20 to 1,200 °C). Ensure that the probe is correctly connected to the analyzer per Figure 3-2 on Page 3-3, and that the probe is at room temperature during warm-up.

Ta Overrange – The temperature measured during warm-up by the optional primary / ambient air thermocouple plugged into the analyzer's T-AIR connector was outside the range of –4 to 212 °F (–20 to 100 °C). Ensure that this thermocouple is at room temperature during warm-up.

UNCALIBRATED SENSORS – List of sensors that do not have a calibration history stored on their printed circuit board. Calibrate each of the sensors listed per Section 5.
