Features 1、[Calibration Function]: The tester calibration is used to eliminate errors in its own components, making the final test results more accurate. Calibration is divided into quick calibration and full function calibration. The full function calibration is accessed from the function menu and requires an additional 220nf capacitor. 2、[Frequency Measurement]: The frequency measurement ranges from 1Hz to more than 1MHz, when the measured frequency is below 25KHz, the period is displayed. 3、[F-Generator]: Squarewave generator with multiple square waves frequencies selectable, turn the test button left or right to switch between different squarewave frequencies, long press the test button to exit the squarewave generator. 4、[10 bit PWM]: Pulse generator, left or right turn the test button to adjust the duty cycle of the pulse from 1% - 99%. Press and hold the test button to exit the pulse generator. 5、[Features]: Capacitance in-line measurement function, two wires can be led from TP1 and TP3 to measure the capacitance value and Equivalent Series Resistance of a 2uF-50mF capacitor in-line, note that the capacitor under test needs to be completely discharged before the test, if the measurement is in-line, the circuit where the capacitor is located needs to be completely disconnected before the test can be carried out. 6、[Resistance Measurement]: Resistance continuous measurement method, constantly test the resistance value and inductance value installed on TP1 and TP3. The inductance is measured only when the resistance under test is less than 2100 ohms, and the inductance is measured from 0.01mH to 20H . Press and hold the test button to exit. 7、[TP1 and TP3]: The capacitance continuous measurement method continuously tests the capacitance values mounted on TP1 and TP3. For small capacitance capacitors, the capacitance values can only be measured in this test method. The equivalent series resistance value is measured for capacitors greater than 90nF with a resolution of 0.01Ω. capacitors above 5000pF show their voltage drop rate after charging. 8、[C(uF)-correction]: This function is used to correct the measured value of the high-capacity capacitance, which is set to 0% by default. This means that there is no correction and is set from -0.2% - 8%. A positive value will reduce the measured value of the capacitor and a negative value will increase the measured value of the capacitor. 9、[Power Supplys]: Type-C 5V power supplys, and compatible with 9V battery power. 10、English Version Function: 11、[Function]: The temperature sensor that uses a single bus communication method to transfer data and has the same package as the triode (TO-92). 1 2、[IR_Decoder]: The IR remote controller decoding function supports two IR remote controller coding formats. All values of the IR decoder function are in hexadecimal format. The IR decoding function only supports single button mode, not continuous mode. 1 3、[IR_Encoder]: The IR remote controller encoder function requires an infrared LED. The tester can control this infrared LED and thus implement an infrared remote controller function. As the tester can only provide a maximum drive current of around 6mA, the control distance cannot be compared to that of a normal infrared remote controller. The IR remote controller encoding supports two formats, the same as the IR remote controller decoding format described earlier. 1 4、[Other Functions]: FrontColor, BackColor, etc. Specification Specifications: Name: Transistor Tester Material: printed circuit board+plastics Type: English Version, Russian Version (Optional) Display: 1.77inch TFT display Input voltage: DC5V Operating voltage: 30mA approx.
