4 Maintenance
Inspection
To maintain operator safety and ensure reliability of the current clamp
it is good practice to
inspect it on a regular basis. Check that the enclosure and optional connection are without
defects such as scratches or breaks.
Jaw surface must be clean. Pollution on jaw surfaces reduces the current clamp sensitivity.
Cleaning
Use a soft cloth moistened with soapy water or alcohol to clean non-metallic surface of the
current clamps
and leave them to dry totally before using it.
!
Do not use liquids based on petrol or hydrocarbons!
!
Do not spill cleaning liquid over the current clamps!
To clean jaw cut surfaces use slightly oiled soft cloth.
Service and Calibration
It is essential that your clamp is regularly calibrated in order to guarantee the technical
specification listed in this Instruction manual. We recommend 2-year calibration interval. Metrel
encloses an original calibration certificate with every new instrument and clamp.
For recalibration and repairs under or out of warranty time please contact your distributor for
further information.
