Maintenance
Use a damp cloth and mild household detergent to clean the instrument should it become soiled through daily use. Never use harsh
cleaning agents or solvents to clean the instrument.
Given operation in accordance with the operating manual, the instrument does not require any special maintenance, with the excep-
tion of the batteries.
To avoid electric shocks, do not allow moisture to penetrate the housing.
Battery replacement
If the batteries are discharged, warning signals are emitted successively and the instrument automatically switches off. Immediately
replace the batteries in order to ensure accuracy of the test values.
Before opening the battery compartment, disconnect the test probes from the test circuit!
To replace the batteries, open the battery compartment on the main housing. Use a suitable screwdriver and unscrew the screws
alternately. When inserting the new batteries, ensure that the polarity is correct.
Carefully close and screw down the battery compartment.
With the aid of an LED, the instrument - without batteries - indicates an applied voltage above the ELV value.
Temperatures below 5 °C can impair the readiness of the voltage tester. Provide a sufficient supply of power by using suitable bat-
teries as specified for the deployed temperature range!
Do not dispose of the batteries in the domestic waste. There will be a collection point near you!
