The DM4070 is a handheld LCR meter for checking the parts a normal multimeter cannot: inductance of coils, chokes and transformers, plus capacitance and resistance. It is a common bench tool for inverter, UPS and SMPS repair.
It measures inductance from 0.1µH to 20H and capacitance from 0.1pF to 2000µF. A zero-adjust knob removes lead error before you measure small capacitors.
