684 is an all purpose clamp meter capable of measuring up to 400 amps inductively and safely. 400 amps will allow testing of electrical systems and alternator outputs, blower motors, electric motors and more. Plus, you have a full digital multi-meter built-in. Hard to access fuel pumps and compressor clutches can be measured too, via one of the Fuse Buddy Current Loops, model 307 or 308. While 684 can measure as high as 400 Amps, it’s low reading resolution is 10 milliamps. Please note, if you’re main reason for buying a clamp meter is battery drains, we recommend our 687 or 688, both of which have 1 milliamp resolution.
