Error and warning codes

If an error occurs in the electronics, the color of the status LED changes from green to red

and the display shows an error or warning code, as outlined below:

• E-code for errors

In the event of an error message, the measured value is unreliable.

• W-code for warnings

In the event of a warning, the measured value is still reliable.
