ESR02 PRO Transistor Tester Capacitance Inductance for Electronic Maintenance

Descriptions: This meter is a small tool for the engineer, electronic maintenance and factory. It is very easy to test plug-in and SMD devices, it can also test different kinds of diodes, triodes, thyristors, MOSFET, enable to analysis the device type, the polarity of the pin, the output HFE, the valve voltage, the junction capacitance of the FET. Notes: 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 6LR61 battery, when the battery power is under 6V, please replace it with a new one Parameters: Resistor: 0 - 50M ohm Resolution: 0.01 ohm Capacitor: 25pF - 100mF Resolution: 1pF Inductor: 0.01mH - 20H Resolution: 0.01mH Capacitor ESR: 2uF-50mF Resolution: 0.01 ohm How to use instructions: Push "POWER / TEST" to power on and start a test, multiple measurements can be repeated by this key, auto power off 20 seconds after measurement Provide three kinds of socket, each socket pin 1, pin 2 and pin 3 are connected There is a table "typical ESR value of electrolytic capacitor" at the back, it is for guiding only, these are typical value for standard grade electrolytic capacitor at room temperature Calibration: Short the test pin 1, 2, 3 together and push "POWER / TEST" button, then the screen prompts to enter calibration, push the button again within 2 seconds to confirm. Few seconds latter the screen prompts to release pin 1, 2, 3, release them and wait for calibration finish Package Weight:0.25 kg Package Size(L x W x H): 17.50 x 10.00 x 6.00 cm / 6.89 x 3.94 x 2.36 inches Package Contents: 1 x ESR02 PRO Digital Transistor Tester 1 x English User Manual
