One-key measurement operation, the power is automatically turned off after a delay. Shutdown current is only 20nA, supporting battery operation.Supports the measurement of two resistances, and potentiometers can also be measured. If the potentiometer is adjusted to one end of it, the tester cant tell the middle and end pins apart.The equivalent series resistance (ESR) of capacitors above 2UF can be detected with a resolution of 0.01 ohms. This feature is important for detecting capacitive performance.Supports the measurement of two resistances, and potentiometers can also be measured. If the potentiometer is adjusted to one end of it, the tester cant tell the middle and end pins apart.The resolution of resistance measurement is 0.1 ohm, and the highest measurement value is 50M ohm.Appearance size: 70mm x 135mm x 24mmPower supply: DC9VColour:WhiteMaterial: ABSPackage Contents:1 * transistor testerOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
