WESLNN ESR02PRO - LCR Meter SMD

Descriptions: This meter is a small tool for engineer, electronic maintenance and factory. It is very easy to test plug-in and SMD devices, it can also test different types of diodes, triodes, thyristors, MOSFETs, allows you to analyze device type, pin polarity, HFE output, valve voltage, FET splicing capacity. Note (Important): Before testing the capacitor, be sure to discharge it, otherwise it may damage the internal circuit If using DC power, choose DC 9V-12V adapter (including 9V and 12V) It is powered by 1 x 9V 6LR61 battery, when the battery charge is less than 6V, replace it with a new one. Parameters: Resistance: 0-50M ohm Resolution: 0.01ohm Capacitor: 25pF - 100mF Resolution: 1pF Inductor: 0.01mH - 20H Resolution: 0.01mH ESR Capacitor: 2uF-50mF Resolution: 0.01ohm How to use the instructions: Press "POWER / TEST" to turn on and start a test, you can repeat multiple measurements with this button, auto shut off 20 seconds after measurement Provide three types of socket, each socket pin 1, pin 2 and pin 3 are connected. There is a table "typical ESR value of electrolytic capacitor" on the back, it is for guide only, these are typical values for standard grade electrolytic capacitors at room temperature. Calibration: Short circuit the test pins 1, 2, 3 together and press the "POWER / TEST" button, then the screen prompts to enter the calibration, press the button again within 2 seconds to confirm. A few seconds later the screen requires you to release pins 1, 2, 3, release them and wait for the end of calibration. Package weight: 0.25 kg Package size (L x W x H): 17.5 x 10 x 6 cm / 6.89 x 3.94 x 2.36 inches. Package Contents (PRO Option Only):
