10. MAINTENANCE AND CLEANING
a) General information
• Turn off the current clamp before cleaning and remove it from the measured object.
• The current clamp does not require maintenance except for occasionally changing the
batteries.
• Under no circumstances should you service any of the components in the interior of the
device. For this reason, never open the product (except for inserting/changing the batteries
as described in these operating instructions).
• Repair or maintenance work must only be carried out by a specialist or a repair centre.
• Always clean the current clamp with a clean, lint-free, antistatic and slightly damp cloth.
• Never use any aggressive detergents or chemical solutions. This could damage the surface
of the current clamp. In addition, do not use any sharp objects to clean the device, e.g.
screwdrivers or metal brushes.
b) Calibrating
• In order to ensure that the measuring device maintains its accuracy over a long period, you
are recommended to calibrate the product once every year.
