Maintenance and service
25.1 Meter check
While it isn’t necessary, under normal circumstances, to perform any
maintenance on the installed meter, the following are check points that
should be observed during scheduled periodic meter visits.
Is the meter dry and clean, particularly the LCD display?
Does the meter display a legible and sensible display? I.e. does the
meter appear in a serviceable condition?
Check all factory fitted and company fitted seals are in place secure
and intact.
Observe display for any error messages or notifications
Confirm that the energy registers have changed to a reasonable
degree since the last visit.
25.2 Meter testing
The testing of meters, either random sample or on all meters should be
carried out periodically per national regulations. The meter must be
removed and replaced with a meter of similar type for the duration of the
tests.
