PREPARATION FOR USE
Fuses:
In doubt, check the fuses using a ohm meter.
Please note that this instrument will not indicate anything, should the
fuses be blown.
Test Leads:
Check the test leads for defects or cracks. Replace if cracked or
damaged. Only replace with the same type
Cleaning:
REPLACING THE BATTERIES

Clean the instrument case with an anti-static cleaner and wipe with
dry cloth.
FUSES REPLACEMENT
Unscrew the back cover and replace the faulty fuse(s) with the same
type, then screw the cover back into place correctly
