10. Battery & Fuse Replacement

10.1 Battery Replacement

The batteries are situated under the analogue insulation tester.

The BAT.OK LED will not lit when the voltage of the batteries i

s low.

Disconnect the test leads from the Instrument, remove the

battery cover and the batteries.

Replace with six 1.5V R6 or L6 batteries, taking care

to observe the correct polarity.

Replace with the new batteries and put the battery cover back.

10.2 Fuse replacement

Remove the battery cover and the batteries first.

Replace with a new fuse.

Only replace with same specification fuse.(0.5A/690V, 6x32mm)
