Warning: For your personal safety, please strictly observe the specifications and precautions for using lithium-ion batteries! Transistor Detection: After the power-off state or test is completed, put the test component into the transistor test area of the test socket, pre the lock handle, pre the multi-function key, the tester automatically measures, and the measurement result is displayed at the end of the test. Warning: Always discharge the capacitor before connecting them to the tester! The tester may be damaged before you turn it on! Warning: We do not recommend using a tester to measure the battery! The battery voltage must be le than 4.5V, otherwise the tester may be damaged!
