6 SERVICE AND MAINTENANCE
6.1 RECALIBRATION
It should not be necessary to recalibrate the meter during its lifetime as it is an
electronic meter with no moving parts and electronics, voltage and current sensors
that do not naturally degrade or change with time under specified environmental
conditions. If 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 sent for repair or exchanged.
6.2 CLEANING
If the meter is dirty and needs to be cleaned, use lightly moistened tissue with
water based mild detergent. Make sure no liquid goes into the meter as this could
damage the meter.
7 SAFETY INSTRUCTIONS
WARNING
Maintenance or reparation should be performed by qualified personnel
familiar with applicable codes and regulations.
Use insulated tools to maintain or repair the meter.
Make sure the protection cover is in place after maintenance or reparation.
