Diagnostic Message
Error Condition
When the display show these messages, the meters has
got a malfunction and must be replaced..
Service and Maintenance
It should not be necessary to recalibrate device during its lifetime as it is an electronic meter with no moving parts with electronics and voltage and current sensors that do not naturally degrade or
change with time under specified environmental conditions. If a degradation in the performance is observed the device has probably been partly damaged and should be sent for repair or
exchanged. If the meter is dirty and needs to be cleaned, use lightly moistened tissue with a water based mild detergent. Make sure no liquid goes into the meter as this could damage the meter.

Firmware Information
Diagnostic Page of the Display
Energy Reset
In any page of the Main Menu by kept push for 10 sec. the
“Menu key”
the diagnostic page of the display appears. If the
“Menu key”
is held down for other 4 sec. the display shows
information about the firmware release and the firmware checksum. If the
“Menu key”
is held down for other 6 sec. is possible to enter in the zeroing menu of the energy counters.
(The zeroing menu is available only in the meter not MID certified.)
When the display shows
“rESET”
the key must be released. To do the reset press it again, afterwards it will go
back to the default visualization with all registers reset. After 4 sec. from the button release if the
