Item Type: Transistor Tester Module <br>Material: Printed Circuit Board <br>Measurement Type: LCR Meter, Voltmeter <br>Model: GM328 <br>Highest Accurate Rate of Resistance Measurement: 0.01Ω <br>Capacitor Measurement Range: from 25pF to 100mF, 1pF Resolution <br>1. Rotating coding switch control, one-key measurement, automatic shutdown. <br>2. When testing a single diode, test the reverse interjunction capacitance of its PN junction at the same time. The interjunction capacitance of triode can also be tested <br>3. For capacitors lower than 25pF, it is necessary to prepare a 30pF capacitor for this test. First, test the 30pF capacitor, and then measure the capacitor to be measured in parallel with it again <br>4. Simultaneously measure the inductance of resistors below 2100Ω, ranging from 0.01mH-20H. The test process is about 2 seconds, larger capacitors and inductors will take longer <br>5. Additional functions include frequency measurement, voltage measurement, squared wave generator, PWM generator, infrared remote control decoding, infrared remote control coding, DS18 B20 temperature sensor test, DHT 11 temperature and humidity sensor test, color selection, debugging and calibration, continuous testing and other functions <br>6. The frequency measurement range is from 1Hz to 1MHz or higher. When the measured frequency is lower than 25kHz, the display period can be achieved, and the resolution can reach 0.001mHz <br>7. Dc voltage is measured up to 50V <br>8. Output one squared wave signal, multiple frequency options, the highest output frequency 2MHz <br>9. Output pulse signal (PWM) with fixed frequency and adjustable duty ratio, and the duty ratio is adjusted from 1%-99% <br>10. Separate capacitor test function, the test mode is continuous measurement, 2uF-50mF capacitor can be directly measured in its circuit (the circuit where the measured capacitor is located must be powered off, the measured capacitor must be fully discharged) <br>11. The thyristor and SCR can only identify their pin distribution, and the trigger current of the thyristor or SCR under test should be less than the current provided by the tester, which can only provide a maximum of 6mA trigger current <br>12. Infrared remote control decoding and encoding support TC9012 and upD6121 two chip encoding formats.1、16 Bits Color Depth: The display unit of this transistor tester module uses a 160x128 PX color display, the entire screen has 8x20 characters, a color depth of 16 bits, and the graphics are displayed as component symbols. <br>2、Auto Detection: This LCR meter module automatically detects NPN and PNP transistors, field effect transistors, diodes, dual diodes, thyristors, thyristors, and automatically determine the pinout of the above transistors. <br>3、Easy Measurement: Measure up to 2 resistors at a time, so the adjustable resistors with three pins can be measured. If the adjustable resistors are adjusted to the end point, then only one resistance value can be measured. <br>4、0.01Ω Resolution: The equivalent series resistance (ESR) of capacitors greater than 90nF is measured simultaneously, and the resolution of ESR is up to 0.01Ω. For capacitors larger than 5000pF, the voltage drop rate after charge is displayed at the same time, which can reflect the quality factor of the capacitor (Q value). <br>5、Easy Detection: The light emitting diode is also shown as the graphic symbols of the diode, and its switching voltage is much higher than that of the ordinary diode. The reverse breakdown voltage under 4.5V of voltage regulator diode can also be detected, displayed as a double diode symbols.1 x <br> <br>Transistor Tester Module<p>4 x Screw</p><p>4 x Stud</p>
