Description: This meter is a small tool for the engineer, electronic maintenance and factory. It is very easy to test plug-in and SMD devices. Automatically detect NPN and PNP transistors, N-channel and P-channel MOSFET, diodes (including double diodes), thyristor, transistors, resistors and capacitors. 1602 LCD display (12864 LCD backlight). Enable to analysis the device type, the polarity of the pin, the output HFE, the valve voltage, the junction capacitance of the FET. Can be powered by a 9V 6F22 battery (not included). Specification: Resistance: 0 ? - 50 m ?; Resolution: 0.01 ? Capacitance: 25pf-100mf; Resolution: 1pf Inductance: 0.01mH-20H; Resolution: 0.01mH Measuring capacitance ESR Resolution: 0.01? Battery: 1 x 6F22 9V (not included) Testing speed: 2s (It takes a long time to measure large capacitance, measuring time to one minute is normal) Material: plastic plus electronic components Size: 13.5 x 8 x 4.5cm/5.3 x 3 x 1.8inch Package Includes: 1 Piece ESR02 PRO Digital Transistor Tester 1 Piece English User Manual Note: Before testing the capacitor, be sure to discharge it, otherwise it may damage the internal circuit If using DC power supply, please choose DC 9V - 12V adapter (including 9V and 12V) It is powered by 1pcs of 9V 6F22 battery, when the battery power is under 6V, please replace it with a new one
