WARNING

•Be sure to use the fuse in same rating (0.5 A/250 V)

so as to ensure safety and performance of tester.

•Do not absolutely use the fuse in different rating or

short-circuit fuse holder terminals with copper wire.

•When operator removes the rear case, do not touch

the internal parts or wire with hand.
