Maintenance
Before any maintenance operations, the clamp must be disengaged from
the conductor and must be disconnected from the external device to
which it is linked.
Maintenance of the magnetic circuit
Keep the clamp jaws as clean as possible. If necessary, clean them
using a soft, lint-free cloth.
Cleaning of the casing
Clean the clamp with a cloth and soapy water. Rinse off with a cloth
moistened with clean water. Never allow the clamp to come into contact
with water. Dry using a dry cloth or pulsed air (max. temperature +70°C).
Calibration verification
Annual verification of the measurement characteristics by an approved
organization.
