5. Maintenance

Warning
To prevent electric shock and damage to the meter
or personal injury, remove test lead before
opening battery cover.

5.1 Replacing the Batteries

5.1.1 When the" "ymbol appears, it indicates the
batteries need to be replaced.
5.1.2 Unscrew the battery cover and remove it from the
meter.
5.1.3 Replace the used batteries with new AAA batteries.
5.1.4 Replace the battery cover and secure it to the meter.

5.2 Replacing the Test Lead (or alligator clip)

If insulation on leads is damaged, replace it.
Warning
Replacement leads must be of the same rating or
higher as the leads supplied with the meter:
600v 10a.
