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.
