A few weeks ago I got a brand new TENMA 72-8155 digital LCR meter from element14. Aside from a digital multimeter, one of the things you must have is a digital LCR meter.
LCR stands for L (Inductance) C (Capacitance) R (resistance). A typical cheap multimeter can measure voltages, current, resistance, continuity. Some of the better ones includes a capacitance meter but not inductance.
I have a Hioki LCR meter (LCR HiTESTER 3522-50) and a Fluke 187 multimeter so I’ve tried doing a resistance test and measure a 100 ohm (1% tolerance) resistor across all 3 meters and see how it goes.
Tenma Reading: 41nF
Fluke Reading: 44.1nF
Hioki Reading: 42.9nF
For general purpose capacitance reading, I think Tenma performed well.
Tenma Reading: 164uH
Hioki Reading: 160.9uH
All in all, it’s not bad at all. To give you a financial perspective, a brand new Hioki LCR costs about $3000. For just $56, I would recommend hobbyists like me to get hold of the Tenma 72-8155 digital LCR.
Apart from the LCR readings, it can also do diode test, continuity, and transistor HFE tests.
