Diagnostics
Below are two conditions your TVOC 2 can be in when it is working correctly:
Diagram 25
The conditions shown below are of the instrument in an error state with potential checks/cures for these faults:
F1 Error
If an F1 error occurs when the instrument is first switched on there may not be an issue. The instrument needs to be
left on for a few cycles to see if the lamp strikes on its own. If an F1 error is still on screen after 5 minutes, then look at
the information below.
Diagram 26
If the F1 error persists for more than 5 minutes, firstly check the red cable between the sensor PCB and the main PCB
is securely connected.
