15. Checking and Changing the FUSE

Disconnect everything from the tester.

Make sure there are no leads connected to the tester 

and that nothing is attached to it. 

The tester must be unpowered and free of any 

potential.

Turn the tester on its back and open the 5 screws.

Now you have access to the PCB.

Check the fuse using an ohm meter.

If the fuse is damaged, then remove the 4 PCB 

screws.

Now you have access to the fuse itself.

Remove the fuse and replace by the same type(10A 

HBC).
