Klein MM600 Multimeter Review 

How do you use a Klein MM600 multimeter?

To use a Klein MM600 multimeter, start by switching it on and setting the range to whatever settings you need for your particular application. Once you’ve done that, connect your test leads to the appropriate terminals on the multimeter and then touch them to the points or wires that you want to test. 

Make sure that they are firmly connected in order to get accurate readings, and be careful not to apply too much force when making these connections as this could damage your meter. Keep in mind that the MM600 is only intended for basic electrical testing, so if you need more advanced functions like data logging or waveform analysis you’ll need to look for a different model with those capabilities. 

All in all, the Klein Tools MM600 is a most affordable multimeter for anyone who needs quick, reliable results from their routine electrical testing.
