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!Feature:Self test with automatic calibrationDisplay:TFT Screen, Color ScreenDiode Range: less than 4.5VZener Diode:Transistor Detect Area: 0.01-4.5VZener Diode Detect Area: 0.01-30VTriac Range: less than 6mACapacitance: 25pF-100mFResistor: 0.01-50MInductance: 0.01mH-20HPower Voltage: 3.7VPower: Built-in Rechargeable Lithium BatteryMeasurement results using TFT graphic display (160x128)One-button operationAuto power off (timeout setting)Built-in high-capacity rechargeable lithium- batteryLithium- battery voltage detectionSupport Chinese and EnglishWarning: Built-in lithium- battery, it is strictly forbidden to immerse the tester in water or near heat source!Warning: For your personal safety, strictly observe the specifications and precautions for using lithium- batteries!Material: Plasticcolour: As shownPackage Contents:1 x LCR-TC1 Transistor Tester KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
