Fuse Block Amp Checker

No need to remove a fuse which reduces the amount of time to determine the current in the circuit. Finding parasitic drains can now be done w/out removing a fuse or resetting the offending circuit. No more - pull a fuse, check the meter, pull a fuse - check the meter... instead, check the complete fuse box quickly. Intelligent audible tones & digital display. Active circuit displays amp value & unit beeps three times. Inactive circuit displays (000) & beeps continuously. Open or blown fuse will not beep & displays (---).
