Klein Tools 69399 – Frequently Asked Questions
1) Which meter does the Klein Tools 69399 fuse fit?
The 69399 is the replacement fuse for the Klein Tools MM720 multimeter. It is sold as the service part for that meter, so if your MM720 has gone dead on the current ranges after an overload, this is the fuse to drop in.
2) What is the rating on the Klein 69399 multimeter fuse?
It is a 6x32, 800 mA, 1000 V fuse, fast-acting and ceramic bodied. Don't substitute a glass automotive fuse of the same physical size, the 1000 V ceramic construction is what limits arc flash energy inside the meter.
3) Should I keep a spare MM720 fuse in the truck or van stock?
Yes, and that is what Klein intends with the 69399. A blown 800 mA fuse takes the current ranges of an MM720 out of service mid job, and at 0.1 oz it costs nothing to carry a spare in the meter case. MRO and fleet buyers standardized on the MM720 typically stock these by the handful.
4) My Klein meter reads voltage fine but won't read amps, is this the part I need?
That symptom points at the current input fuse, and on an MM720 the 69399 is the fuse that protects it. Voltage ranges stay live because they don't pass through the current fuse, so losing only amp readings is the classic blown fuse signature.
