ماژول تستر قطعات الکترونیکی LCR-T4 بدون نمایشگر
معرفی
تستر قطعات الکترونیکی LCR-T4
می تواند مقادیر مورد نظر قظعه مورد تست را به صورت خودکار اندازه گیری نماید. به
همین دلیل استفاده از آن برای کاربر بسیار آسان بوده و برای علاقه مندان به
الکترونیک ، توسعه دهندگان الکترونیک، طراحان و تعمیر کاران الکترویک انتخاب بسیار
مناسبی است. تستر قطعات الکترونیکی LCR-T4 می تواند مقادیر قطعاتی همچون مقاومت، خازن،
سلف، دیود، ترانزیستور ، SCR ، MOSFET و … را اندازه گیری کند. به کمک این دستگاه
می توان نوع قطعه ، قطب ها ، مقدار HFE ترانزیستور، ولتاژ ترشولد و … را تشخیص داد.
Introduction
The
tester is stable and easy to use which can automatically read out the accurate
data, and is suitable for electronic enthusiasts, electronic developers,
designers, and electronic repair. It can measure all kinds of resistance,
capacitance, inductance, two tubes,transistors, SCR, MOS field effect tube; can
determine the device type, polar, pin output HFE,threshold voltage, the
junction capacitance of the field effect tube. It is particularly suitable for
transistor pairing and hybrid surface mount component identification, is the
best partner of amateur DIYer.
One key to boot, one key test, automatic recognition device type, automatic
switching range, automatically shut down after the test.
standby power consumption can be ignored, and can be used in battery powered.

the tester can not distinguish the middle and both ends of the pin)

the testing, double emitting two tubes detected as the double diode.
4.5V it shows two pieces diodes, and it can be confirmed by the voltage. The
probe around the diode symbol is the same,in this case, you can identify the
diode true anode by the threshold voltage at 700mV more or less!
transistor also can be measured, and then must be connected with the base and
collector or emitter.
0.2nF~7000uF, if the test value is below the 25pf capacitor, and a diode in
parallel manner or at least 25pf shunt capacitor. After get the measured
results, then use it to minus parallel capacitor solute.
resistance could be identified as inductance, the measurement results show only
a single inductor, and display the inductance value.
measurement time will be extended as the actual value.
