Only use specified spare parts for maintenance purposes. The

manufacturer cannot accept any responsibility for accidents occurring

following repairs carried out outside its after-sales department or approved

5.1 Cleaning

The clamp must not be clamped to a cable and must be disconnected from the

measuring device. Do not splash water onto the clamp.

n Keep the jaw gap perfectly clean. Remove dust with a dry, soft cloth. Wipe the

iron jaws from time to time with an oil soaked cloth, in order to prevent rust

from forming.

n Clean the unit with a cloth and a little soapy water. Rinse with a damp cloth.

Then dry quickly with a cloth or pulsed air at 70°C max.

calibration, contact one of our accredited metrology laboratories (information

and contact details available on request), at our Chauvin Arnoux subsidiary

or the branch in your country.
