تستر هوشمند قطعات الکترونیک  قابدار شارژی باطری دار با LCD رنگی بزرگ مدل جدید T7

LCR Meter

یک طرج جدید و متمایز ارزنده جدید:

این مدار با کمک میکروکنترلر خانواده AVR طراحی شده و یک تستر و آزمایشگر اکثر قطعات الکترونیکی است که مجهز به صفحه نمایش LCD بوده و قادر است قطعات الکترونیکی متفاوت را تست کرده و نتیجه تست را بر روی صفحه نمایش LCD  خود گزارش داده و به نمایش بگذارد :

از جمله قطعاتی را که این تستر هوشمند قادر به تست و شناسایی و اعلام صحت و خرابی آنست را میتوان چنین بر شمرد :

مقاومت ها - با تعیین مقدار دقیق آن

دیود ها - با تعیین صحت و سلامت یا خرابی آن و ظرفین خازنی آن

ترانزیستورها ی معمولی - UJT - BJT - FET - JFET - MOSFET و ... با تعیین مشخصات ولتاژ و ظرفیت خازنی و بتا hfe و پایه های آن

تریستورها و تریاک ها

جالب اینکه نیازی نیست شما قطعه را بشناسید و اصلاً پایه های آنرا بدانید !!!

این تستر هوشمند خودش پایه ها را نیز شناسایی کرده و حتی به شما مثلاً در مورد ترانزیستور ، پایه های بیس ، کلکتور و امیتر آنرا نیز برای شما مشخص کرده و بر روی LCD گزارش می کند .

Description:
This is an LCR-TC7 Multi-functional Electronic Component Tester that can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel, and P-channel MOSFET, IGBT, JFET, Triac, and battery, etc. It can also be used to detect infrared waveforms, Zener diode and includes the function of self-calibration.
After detection, align the infrared remote control with the “IR” light, then press the button on the remote control, if the detector successfully decodes it, it will display the data code and infrared waveform.
One button operation automatically detects and shutdown, and you can press the multi-functional button to close the detector too.
Put the pins of the component in the corresponding area, then dial the little handle and the detector will test it automatically, finally, the results will display on the backlight TFT screen clearly.

Attention:
All ways are sure to discharge capacitors before connecting them to the Tester! The Tester may be damaged before you have switched it on. There is only a little protection at the MCU’s ports. Extra caution is required if you try to test components mounted in a circuit. In either case, the equipment should be disconnected from the power source and you should be sure, that no residual voltage remains in the equipment.

This is an inexpensive component tester called the FISH 8840 which you can find from many online eBay retailers for around $30. The interface is very simple, attach a device to be tested and press the test button. It turns off after about 20 seconds, pressing the off button puts it into sleep mode immediately. There is a ZIF socket that allows you to insert leaded devices and pads that allow you to press SMD devices directly onto the tester. Their are number 1 through 3 on the tester where you connect the device under test to and then the screen will display the recognized component with the lead numbers on a component schematic picture. There seems to be an issue with the capacitor testing mode with a range of values, I will discuss this with the seller to see what the resolution to this is. I have seen this tester work fine with capacitors so I think it is just something with this one. You can see the features and functions below.

“NEW Function:
1:Automatic detection of NPN and PNP transistors, n-channel and p-channel MOSFET, diode (including double diode), thyristor, transistor, resistor and capacitor and other components
2: Automatic test the pin of a component, and display on the LCD
3:Can detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltage
4: Measure the gate and gate capacitance of the MOSFET threshold voltage
5:Use 12864 liquid crystal display with green backlight
Size:140*90*55MM
Specifications: For you reference
1 two -button operation, automatic shutdown .
2,Only 20nA shutdown current.
3,Automatically detect NPN, PNP bipolar transistors , N -channel and P -channel MOS FET, JFET , diodes , two diodes, thyristors small power unidirectional and bidirectional thyristor.
4,Automatic identification components pin arrangement .
5,Measuring bipolar transistor current amplification factor and base – emitter threshold voltage.
6,Via the base – emitter threshold voltage and high current amplification factor to identify Darlington transistors.
7,Can detect bipolar transistors and MOS transistors protection diodes.
8,Measuring the gate MOS FET threshold voltage and the gate capacitance.
9,Can simultaneously measure two resistors and resistor symbol is displayed. Displayed on the right with a decimal value of 4 . Resistance symbol on both sides shows the pin number. So you can measure the potentiometer. If the potentiometer wiper is not transferred to an extreme position , we can distinguish the middle and both ends of the pin.
10,Resistance measurement resolution is 0.1 ohms , 50M ohms can be measured .
11,Can measure capacitanceCan measure capacitance of 30pF-100mF , resolution 1pF.
12.2uF more capacitors can simultaneously measure the equivalent series resistance ESR values. The two can be displayed with a decimal value , resolution 0.01 ohms.
13,Can be in the correct order and the diode symbol display two diodes , and gives the diode forward voltage.
14.LED is detected as a diode forward voltage higher . Combo of the LED is identified as two diodes.
15,Eeverse breakdown voltage is less than 4.5V Zener diode can be identified.
16,Can measure a single diode reverse capacitance. If the bipolar transistor connected to the base and collector or emitter of a pin , it can measure the collector or emitter junction reverse capacitance .
18 can be obtained with a single measurement rectifier bridge connection.
Notice: Before measuring capacitance , the capacitor must be discharged , otherwise very likely damage the meter .”
