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.
