Input protection: Maximum DC or AC 600V RMS.

REPLACING THE BATTERIES

• 

Turn off the power supply and disconnect the probe from the measured circuit.

• 

Loosen the screws used for fixing the battery cover and remove the battery cover.

• 

Remove the old batteries and replace with new ones.

• 

Mount the battery cover and and tighten the screws.

RECYCLING INFORMATION

This symbol indicates that separate collection of Waste Electrical and 

Electronic Equipment (WEEE) or waste batteries is required. Do not dispose 

of these items with general household waste. Separate for the treatment, 

recovery and recycling of the materials used. Waste batteries can be returned 

to any waste battery recycling point which are provided by most battery
