1.3 Prevention and elimination of malfunctions
If suspected that meter works improperly, the following actions should be performed:
1.3.1 Exterior inspection
Before applying voltage to the meter makes sure its case has no mechanical damages, there
are no signs of overheating, and all wires are properly connected.
Do not plug a meter into network if it is mechanically damaged. This can cause
staff injuries and destroy meter as well as other equipment!
Before switching on network voltage, it is necessary to check if sliding voltage
link is connected (see chapter 5.7 Sliding voltage link).
1.3.2 Inspection of connection and parametrization constants
Installing, uninstalling, parametrization and verification can be performed only by authorized
organizations that have qualified technicians. After plugging a meter into electric network
technician should check whether date and time are correct, whether meter shows right
energy direction, valid tariff time zone and calendar, tariff seasons.
1. If meter shows wrong date and time, a representative from the organization in charge of
the meter installation should be informed.
2. If LCD indicator shows a warning note ‘Er’, the meter should be uninstalled and passed
for repair works.
3. If energy direction is wrong, technician should check whether inputs are connected
properly to terminal block.
4. If meter calendar season, season time name or valid tariff time zone does not correspond
to real situation, meter’s parameterization data has to be checked and errors has to be
corrected by repeated meter’s parameterization.
1.3.3 Procedure of meter returning to manufacturer
