2. Safety Check
Before using the tester, check the condition of the test
leads, the fuse, and general appearance.
The leads must be free of cracks or any damages and
must be insulated as when they were new.
Fuse replacement is described later in this user's
manual.
Before replacing the fuse, always disconnect all leads
and then remove the cover to access the internal
circuitry.
When replacing the fuse, use only the type specified
(HRC fuse), and insert correctly into the fuse holder.
Always double check the lead connections before
making any measurements.
