Description:
M328 DIY transistor tester kit can automatic detect PNP and NPN bipolar transistor， N， P-channel MOSFET， JFET field effect transistors， diodes， two diodes， thyristors， resistors(0.1 Ohm - 50M Ohm)， capacitors， inductors. Automatic detection of current amplification factor (B)， pin definitions and emitter junction (Uf) through a high threshold voltage and high current in two seconds.

Main Features:
● One key for measurement operation， auto power off delay. Shutdown current is only 20nA， support for battery operation
● Capacitance measurement range from 25pf to 100mF. 0.09uF capacitance can be detected above the equivalent series resistance (ESR)， resolution is 0.01 ohms
● Inductance measurement range from 0.01MH to 20H， otherwise it will be displayed as resistance if the inductor DC resistance is higher than 2100， that will be displayed as the European resistance.
● The square wave signal generator can produce optional built-in stall square wave signal within the range of 1HZ - 2MHZ
● PWM pulse signal generator produce the pulse width modulated signal of 1 - 99 percent
● The frequency meter function can test 1HZ - 25KHZ or higher frequency signal (in this case a slight decrease in accuracy)
