True RMS (major feature)
Frequency (nice feature)
Capacitance (nice feature)
Thermocouple and microampmeter (nice features)
Overall a good piece of equipment, Flukes have a really good reputation, and are pretty tough.
The optional amp clampmeter is a must if you ever want to see if a heater is working. Measuring voltage across one says the switch is good, the current says the heater is good. If you have one dead heater among 4 it is a major feature.
Double check the specs.. I only saw a microamps scale (600). If that's all you need, it's all good, but most people prefer a higher current capability.
