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: 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 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, please 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 are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
