Specification: Item Type: Transistor Tester Model No.: LCR-T4-MAX Material: Printed Circuit Board, LCD Battery: 1 x 9V 6F22 battery, without battery. Uses: can measure various resistances, capacitances, inductances, diodes, triodes, thyristors, MOS field effect transistors. It can also determine the type of device, the polarity of the pins, the HFE output, the valve voltage, the binding capacitance of the field effect transistors. Display: 12864 LCD Backlight Color: White Backlight Operating temperature: 0~40℃ Storage: -10~60℃ Relative humidity: non-condensing <10°C Note: 1. One key to start and test, automatically identify the type of device, automatically change the range, and automatically turn off after testing. 2. The standby current is as small as 20na, and the standby power is negligible for a long standby time, and the battery can be used as a power source. 3. Automatically detects PNP and NPN type bipolar transistors, N-channel MOSFETs, P, JFET, diode, dual diode, thyristor thyristor (thyristor), triode, resistance, capacitor, capacitor ESR value. 4. It automatically detects the design of the pin and assigns the tag according to the actual sequence. 5. Measure the current amplification factor β of the bipolar transistor, the threshold voltage of the emitter junction, and the leakage current ICE.
