![]() ![]() ![]() The inductance measurement uses pulse measurement method. The highest resolution is 0.1 ohm resistance measurements, the highest measured value of 50 megaohms. If DC resistance of inductor is higher than 2100 ohms or inductance outside of that range, inductor is detected as being resistor. Inductance measurement range of 0.01MH-20H. Upport two resistance measurements (so potentiometer can also be measured).Įach test takes about two seconds for normal components, but measuring large capacitance and high inductance measurements can take a longer time Check also discussion.Īutomatic detection of PNP and NPN bipolar transistor, N, P-channel MOSFET, JFET field effect transistors, diodes, two diodes, thyristors, resistors, capacitors, inductors. This design is clearly based on AVR Transistortester project that has some software at Github. The instruction manual is available on-line. This is a DIY kit you need to solder together and after that calibrated. The ZIF socket has 3 different pins wired to it: The first three columns are for pin 1, the fourth column is for pin 2 and the last three columns are for pin 3. The components can be connected to supplied ZIF socket or you can solder your own test cables. ![]() The nominal working current is 24mA 9V and shutdown current is said to be only 20nA. ![]() The device works on DC power supply 5.5-12V. When more advanced functionality is needed, it can be selected with rotary control. For basic automatic component measurement, you can do it just by pressing down the encoder (works like old single button). The whole set of functions are controlled by a rotary encoder switch control that replaces the single button used on previous models. The signal is output from pin 2, the negative terminal of the power supply is always GND (can use pin 3 for this). The square wave signal generator has range of 1HZ-2MHZ TTL square wave signal. PWM pulse signal generator for 1-99% of the pulse width modulated signal at around 7.8 kHz pulse rate. In addition to component measurement, this device has a quare-wave generator and PWM pulse signal generator. The frequency measurements seems to work at signal amplitude from around 30 mV up to 5V TTL signal. It can measure higher frequencies with reduced resolution (measured nicely to 150 kHz). It can measure 1HZ-25KHZ at good resolution. This kit has also frequency meter function. For inductor you get inductance and resistance. For capacitance measurement it measures the capacitance and ESR. The included features are resistors, capacitors, inductors, diodes, transistors, SCR, and most commonly used devices will automatically recognize and measure with graphical display of measurement results. This kit has same display as Component tester M12864 but includes more features. Now it is time to test the next improved version of the same idea: Original Hiland DIY M12864 Graphics Version LCR ESR PWM Transistor Tester Kit (was on sale for less than 10 Euros) I have earlier tested basic DIY Electronics Tester Kit M168 and more advanced Component tester M12864. Transistor tester M12864 advanced version ![]()
