Provide three kinds of socket, each socket pin 1, pin 2 and pin 3 are connected. The placement of the device does not require the order of instruction, and the screen displays the component function of each pin after measuring. There is a table typical 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 List: 1 x Transistor Tester 1 x User Manual Note: Before testing the capacitor, be sure to discharge it, otherwise it may damage the internal circuit. If using DC supply, please choose DC 9V~12V adapter. (including 9V and 12V) Can be powered by a 9V 6LR61 battery (NOT included), when the battery power is under 6V, please replace a new one.
