My Analox O2 EII sensor is showing the following code L20.6. Can you tell me what this means?
The symbol for a low battery warning is shown by 'L' on the display.
When present, please change the battery before using the instrument. Please replace the battery with a 9V Alkaline (PP3) battery
My Analox O2 EII sensor is showing the following code t00.0. Can you tell me what this means?
As mentioned above, the low battery warning on the O2EII is shown by an 'L' on the display. If the O2 sensor has failed or the O2 sensor cable has been damaged, the display usually will be -00.0.
If your battery is running low and the O2 sensor is depleted (or O2 cable is damaged), then the 'L' and '-' symbols will overlay and show as a 't'.
Check the condition of the O2EII O2 wire, replace the the O2 sensor, replace the battery.
