a) general Information
The current injection probe requires no servicing apart from replacing the battery/rechargeable
battery from time to time.
To warrant meter accuracy for an extended period, it is recommended to have the device
calibrated once per year.
b) Cleaning
The connected lines of the meter must be disconnected from the meter and all objects to be
measured before the product is cleaned. Switch off the current injection probe first.
Do not use any aggressive cleaning agents such as petroleum, alcohol or similar for cleaning.
This may damage the meter‘s surface. Also do not use any sharp-edged objects such as
screwdrivers or medal brushes for cleaning.
Always clean the current probe and the measuring lines with a clean, lint-free, antistatic and
slightly moist cloth.
