Cal-Van 74 Amp Hound ATM/ATO/MAXI Fuse Current Tester
The Cal-Van 74 Amp Hound checks current at supported ATM, ATO and MAXI fuses while the fuse remains installed. Audible feedback accompanies the display, helping distinguish a circuit drawing current from an inactive circuit or an open fuse indication.
Specifications and included details
- Current checks without removing the supported fuse.
- Active circuit: three beeps and an amp-value display.
- Inactive circuit: continuous beeping and 000 display.
- Open or blown fuse indication: no beep and a dash display.
Before ordering
Match the fuse type and follow the tester instructions for probe contact. A zero-current result describes the circuit at that moment; it does not establish that the connected equipment or wiring is fault-free.
Product questions and answers
Do I need to pull the fuse to check current?
No. The stated function checks circuit current without removing the supported ATM, ATO or MAXI fuse.
Is 000 the same indication as a blown fuse?
No. Inactive circuits are described as 000 with continuous beeping; an open or blown fuse gives dashes with no beep.
Does an inactive circuit result prove everything is working?
No. Current depends on the circuit's operating state. Check whether the load should be active before interpreting the result.
