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. Hard to access fuel pumps and compressor clutches can be measured too, just add one of the Fuse Buddy Current Loops, model 307 or 308. While 684 can measure up to 400A, it’s low reading resolution is 10 milliamps. However, 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. FEATURES:
• Clamp on current measurements up to 400 Amps
• Auto-ranging digital multimeter built-in
• CATIII 600V safety rating, 4000 count LCD
• Backlit LCD display
• Includes zippered storage case
