7.3 Checking and Replacing the Fuse
• To avoid electric shock, always turn off the POWER switch and unplug the
AC power cord from an electrical outlet before performing inspections or
replacing the fuse.
• To avoid electric shock, make sure that the replacement fuse is of the cor-
rect shape, rating, and characteristics for tester specifications. Never use
a fuse having a different rating; never short-circuit the fuse holder.
1. Turn off the POWER switch and unplug the AC power cord from the
electrical outlet.
2. Disconnect the AC power cord from the AC LINE connector on the rear
panel.
3. Use a screwdriver to remove the fuse holder, as shown in Fig. 7-1.
