Color screen graphic display m328 transistor tester resistance meter inductance meter capacitance meter ESR Tester instrument

Simple operation instructions: 1,2,3 pins are connected at will, automatic identification type, automatic detection of pin sequence, graphic display, automatic measurement parameters, very simple. For example. You connect a triode, you don't need to consider the BCE order of 123, plug it in at will. Then press the test key. It automatically identifies whether it's a triode, a FET, a thyristor or a resistor capacitor.... After identifying the triode, test whether it is NPN or PNP, and then judge the BCE order. Show it graphically, and then tell you the magnification, conduction voltage, etc. Basically you just plug it in and press the button. The rest will tell you what it is Description of test scope: Transistor range: transistor composed of less than 2 PN junctions, no other resistance and capacitance components inside. Resistance measurement 0.5 O - 50m O Inductance measurement 0.01mh-20h Capacitance measurement 25pf - 100000 UF Function introduction: 1: One key measurement operation, automatic power off after delay. The turn off current is only 20na, which supports battery operation. 2: Automatic detection of PNP and NPN bipolar transistors, N, p-channel MOSFET, JFET, diode, double diode, SCR, resistance, capacitance, inductance. Automatic detection of pin definition. 3: The current amplification factor (b) and conduction voltage (UF) of the bipolar transistor are measured. Darlington transistors can be identified by high threshold voltage and high current amplification factor. 4: The protection diode inside bipolar transistor and MOSFET can be detected and displayed on the screen. 5: The threshold voltage and gate capacitance of MOSFET are measured. 6: It supports the measurement of two resistances, and the potentiometer can also be measured. If the potentiometer is adjusted to one end of it, the tester cannot distinguish between the middle and both ends of the pin. 7: The resolution of resistance measurement is 0.1 ohm, and the maximum measurement value is 50m ohm. 8: Capacitance measurement ranges from 25pf to 100mf (100000 UF). The resolution can reach 1 PF, and the inductance measurement range is 0.01mh-20h. Otherwise, it will be displayed as resistance. If the DC resistance of the inductor is higher than 2100 O, it will also be displayed as resistance. During capacitance test, the vloss displayed on the screen means loss and attenuation. The larger the value, the closer the capacitor is to scrap! ESR is the impedance. The smaller the value, the better the capacitance performance! 9: It can detect the equivalent series resistance (ESR) of capacitors above 2uF with a resolution of 0.01 ohm. This function is very important for detecting capacitance performance. 10: The symbol of the correct direction can be displayed for both diodes, and the forward voltage drop can be displayed at the same time. 11: The LED is detected as a diode, and the forward voltage drop is higher than the normal value. The dual LED is detected as a dual diode. At the same time, the LED will flash. 12: Each test time is about two seconds, only large capacitance and inductance measurement will take a longer time How to switch languages: 1. Install the 9V battery and press the test power on button 2. When a graphic logo appears, press and hold the test button, the language selection interface will appear, and then press the test button to select 3. After selecting the language, press and hold the test button to select the language
