2019 Transistor tester esr meter Frequency PWM square wave LCR table
 
 
　 
Description:
  • Features:

    The tester size: 69mm * 69mm * 33mm (including high copper pillow and encoder knob)
    Using full color display display data pixel area 160 * 128
    Operating voltage: external battery 9V external 12V DC DC power supply
    1: display unit using 160x128 pixel color display, color depth 16-bit, graphic display symbol
    Rotary code switch control, one-touch measurement, automatic shutdown
    2: the use of 9V cascading battery-powered, you can also use the power adapter power supply, the whole current of about 30mA, 20NA after the power off automatically detect NPN and PNP transistor, FET, diode, double diode, thyristor, SCR, automatic Discriminating the transistor pin distribution
    3: Test NPN and PNP Transistor Common-emitter Current Amplification Coefficient, Base-Emitter Threshold Voltage, Cut-off Collector-Emitter Leakage Current Through Triode Base-Emitter Threshold Voltage vs. High Current Amplification Coefficient. Limon Transistor Detection Power. Transistor and Field Effect Transistor Built-in Protection Diode Test Field Effect Gate Gate-Source Gate-Threshold Voltage, Drain-Source On-Resistance, Gate-to-Source Capacitance
    4: a maximum of two resistors measured at once, so three adjustable resistors can also be measured, if the adjustable resistor is transferred to the end, it can only measure a resistance value measured the highest resolution 0.01Omega. Can measure the maximum 50MOmega capacitor measurement range from 25pF-100mF, resolution 1pF. For capacitors larger than 90 nF, the equivalent series resistance (ESR) is measured at the same time. The resolution of the equivalent series resistance is 0.01Omega. For capacitors larger than 5000pF, the voltage drop rate after charging is displayed. This value reflects the quality factor (Q) of the capacitor.
    5: a maximum of two diodes measured at a time, showing its positive and negative, conduction voltage, light-emitting diodes are also shown as diodes of the graphic symbols, the conduction voltage is much higher than the ordinary diode reverse breakdown voltage is lower than 4.5V The voltage diode can also be detected and shown as a double diode symbol. Its positive and negative to the conduction voltage of about 700mV diode symbol prevail, the other diode symbol corresponding to the conduction voltage is the regulator value. So do not test a single diode and a Zener diode at the same time to test a single diode, while testing the PN junction of the reverse junction capacitance, the transistor junction capacitance between the PN junction can also be tested, then only at the same time into the transistor Base and emitter, or base and collector pairs of capacitors less than 25pF can also be tested, this test need to prepare a 30pF capacitor, first test 30pF capacitor, and then measured in parallel with the capacitor measured again, with The results obtained by subtracting the 30pF capacitor are measured at 2100Omega or less while measuring the inductance of the capacitor. The measurement range is from 0.01mH to 20H for about 2 seconds. Large capacitors and inductors can take longer.
    6: Additional features include frequency measurement, square wave generator, PWM generator, color selection, commissioning calibration, continuous testing, and other functions,
    7: frequency measurement range from 1Hz to 4MHz, measured frequency below 25kHz, can display the cycle, the resolution can be 0.001mHz
    8: output all the way square wave signal, multi-file frequency to choose from, the maximum output frequency of 2MHz (square wave has a large waveform distortion) is not distorted state is within 800KHZ!
    9: output a fixed frequency, adjustable duty cycle pulse signal (PWM), duty cycle adjustment from 1% -99%
    10: a separate capacitance test function, the test method for continuous measurement, the 2uF-50mF capacitor can be measured directly in its circuit, (measured capacitance of the circuit must be power, the measured capacitance to be fully discharged after)
    11: thyristor and thyristor can only identify the pin distribution, and also need to be measured thyristor or thyristor trigger current is less than the tester can provide the current, the tester can only provide up to 6mA trigger current
    Note: Before testing the capacitor, be sure to discharge the capacitor first. Otherwise it may damage the tester's microcontroller
