MULTIFUNCTIONAL TESTER: This tester is a multifunctional vehicle circuit tester with a monolithic processor and a liquid crystal display. it can be used to measure DC voltage, continuity, and the amount of current in fuse, Because the tester uses a new method to measure current, it is unnecessary to remove the fuse; just connect the two probes to the two terminals of this fuse. lt can measure a DC voltage as low as 0.1mV.

LITTELFUSE FUSE/USER DEFINE MODE: Connect the test lead, according to the size of the fuse to be tested and the rated current mark on this fuse, determine the type of this fuse and its rated current, or use USER DEFINE mode to measure the current of a fuse. Connect the test leads to the two terminals of the fuse to be tested (for blade fuses, connect the test leads to the two contacts on the top of fuse). The primary display indicates the amount of the current in the fuse under test.
