pack (see “Accessories” on page 36), contact Elcometer or your local

Elcometer supplier.

Charging the batteries

The rechargeable battery must be fully charged before using the Covermeter for

the first time. Use the charger supplied with your Covermeter to charge the

battery; use of any other type of charger is a potential hazard, may damage your

Covermeter and will invalidate the warranty. Do not attempt to charge any other

batteries with the supplied charger.
