Review on 🧪 Enhanced 12864 Mega328 ESR Transistor Resistor Diode Capacitor Mosfet Tester with Test Hook: Accurate Component Measurement by Derrick Wilson

Mine arrived well packaged and working. I mounted the board and battery holder on a small wooden plank so I could move it without lugging the battery around. I've tested it with capacitors, inductors, transistors, diodes, LEDs and resistors. He pointed out the correct value/polarity and also showed the schematic. I checked the measurements with other test devices and found no significant difference in the values. The sampling time is only a few seconds. I reach for this device more often than my multimeter to check components. Small hook probes easily connect to the ZIF connector. and there is also a conductive pad that you can also click on the pins to check. It turns off automatically after the test is complete, and a 9-volt battery (not included) lasts a very long time. That saved me from buying an expensive LCR meter for the time being. But it should definitely stay in the laboratory. Without a protective case, it is probably too fragile for normal field use. No complaints, but for $12 I'm very happy with it.
