  • Measure DC current directly at the fuse with dedicated modes for MINI, ATC/ATO, and MAXI automotive fuses.
  • See circuit status instantly with color-coded indicators for inactive, active, and potentially open fuse conditions.
  • Work more easily around the vehicle with Auto Hold, a rotating display, magnetic mounting, adjustable backlight, and built-in flashlight.
Product description

The Fuse Monitor is used to locate / isolate which circuit parasitic draw lies by measuring current across fuses without removing them. The PPFUSE can be used on Maxi, Mini, & ATC fuses with a maximum Amp rating of 80A. The Fuse Monitor calculates amp draw based on fuse size in real time. The PPFUSE is USB-C rechargeable, comes with a belt clip, has replaceable tips, and a work light.

Test the fuse. See the current. Know the status.

Direct fuse current measurement

Touch the probes to the fuse test points to measure current without adding a separate ammeter to the circuit. Select MINI, ATC/ATO, or MAXI mode to match the fuse being tested, with measurements displayed to 0.01A resolution.

Color-coded fuse status

Get an immediate visual indication of circuit activity with green, yellow, and red status indicators. Green indicates less than 0.05A, yellow indicates current flowing through the fuse, and red indicates the fuse may be open or blown.

Built for hands-on diagnostics

Keep the reading visible wherever you work with Auto Hold, rotational display detection, magnetic mounting, adjustable backlighting, and a built-in flashlight.
