Service and maintenance
OBS! Disconnect and make sure that it is absolutely safe to
enter the installation before any service and maintenance
actions or attempt to clean the meter.
Control on a regular basis that the connections to the meter are
correct with respect to torque, insulation etc. Inspect also the
wires with respect to wear and tear. There is no service or
maintenance required for the meter itself. A meter with mal-
function cannot be repaired and hence it must be replaced.
Recalibration
It should not be necessary to recalibrate the meter 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 accuracy is
observed the meter has probably been partly damaged (for
example due to lightning strike or extreme environmental
conditions etc.) and should be exchanged.
Cleaning
If the meter is dirty and need to be cleaned, use lightly moist-
ened cloth with a water based mild detergent. Make sure no
liquid goes into the meter as this could damage the meter and
cause danger.
