M328 Multifunction Transistor Tester LCR Diode Transistor Capacitance ESR meter PWM Signal Generator diy kis Description: Product Details: A key measurement operation , auto power off delay . Shutdown current is only 20nA, support battery operation. Automatic detection PNP and NPN type bipolar transistors , N, P -channel MOSFET, JFET FET , diodes , two diodes, thyristors , resistors , capacitors , inductors. Automatic detection pin definitions. Measurement of the bipolar transistor current amplification factor (B) and conduction voltage emitter junction (Uf). Darlington transistor may be identified by the amplification factor of the high threshold voltage and high current. Can be detected inside the bipolar transistor and MOSFET protection diodes and displayed on the screen. The threshold voltage and the MOSFET gate capacitance measurement. Support two measuring resistors , the potential can also be measured . If the potentiometer is adjusted to its end , the tester can not distinguish the two ends of the pin and the middle. Resistance measurement resolution is 0.1Ohm , the highest measurement value of 50MOhm. Capacitance measurement range from 25pf to 100mF (100000UF). Resolution up to 1PF. Can detect more than 2UF capacitor equivalent series resistance (ESR), with a resolution of 0.01Ohm. This feature is very important for the detection capacitor performance. You can display symbols of the two diodes in the right direction , also shows the forward voltage drop. LED detection of diode forward voltage drop higher than normal . Dual LED detected as double diodes. Simultaneous detection of light-emitting diodes will flash. Each test time is about two seconds , only large capacitance and inductance measurements will take a long time. New conversation function, you can select the following additional functions via the menu:1. The square wave signal generator, optional built-in within the range of 1HZ-2MHZ stall square wave signal;2.PWM pulse signal generator for 1-99% of the pulse width modulated signal;3. The frequency meter function, can test 1HZ-25KHZ or higher frequency signal (in this case a slight decline in accuracy, this feature should make their own extensions) Specification: Measurement Range: Resistor: 0.5Ω ~ 50MΩ Capacitor: 30pF ~ 100mF Inductance: 0.01MH ~ 10H Working voltage: can use 6FF22 9V Battery, or DC 5.5V ~ 12V via DC socket Controller: ATmega328 (has been programmed) Standby current: 0.02uA Operating current: 25mA Note: When measuring 1 uF non-polarity capacitance, attention to short-circuit capacitance between two feet and put off storage of electricity when measuring capacitance, otherwise may damage the instrument, if measuring instrument with electricity is easily to make display show CELL and can't use normally, we are not responsible for this kind of situation, what you can do is replacing the chip, it is important to note, please! if need dada .we will sent you email.
