Self-Diagnostic Function; Power Failure Memory; Applicable Standard - Panasonic KW2G User Manual

9.7 Self-diagnostic function

If an error occurs, the following indication will be given.
Indicator
Err0 CPU error
Err1 Memory error*
*Includes the possibility that the EEPROM's life has expired.

9.8 Power Failure Memory

Eco-POWER METER memories integrated electric power and working status to internal EEPROM until
when power supply is off. (Power failure guarantee)
And every time to change each setting, each setting value is memorized to internal EEPROM at the
same time. Therefore, change setting frequently makes EEPROM's life short. Avoid to usage like this.
*Especially be careful if you set by communication.
