Transistor Detection: After the power-off state or test is completed, put the test component into the transistor test area of the test socket, press the lock handle, press the multi-function key, the tester automatically measures, and the measurement is displayed at of the test. Warning: Always discharge the capacitor connecting to the tester! The tester may be damaged you turn it on! Warning: We do not recommend using a tester to measure the battery! The battery voltage must be less than 4.5V, otherwise the tester may be damaged!
