Automatic detection of NPN and PNP transistors, field effect transistors, diodes, double diodes, SCR, automatic detection of transistor pin-out, SCR can only detect their pinch-out and the trigger current of the SCR to be tested Test the common emitter current gain factor of the NPN and PNP transistor, the threshold voltage of the base electrode and the emitter electrode, the leakage current of the collector emitter electrode. Identify the Darlington Transistor by using the threshold voltage between the base electrode and emitter electrode of the transistor and the high current gain. Separate capacity function test, the test mode of continuous measurement of 2uF-50mF capacitors can be measured directly in its circle The display unit has a 160x128 colour display, full screen characters 8x20, 16-bit colour depth and graphical elements, display symbols, rotary switch control, one-button measurement, automatic shutdown. Use a laminated 9V battery, you can also use a power supply (DC 6.8-12V), the total current is about 30mA and then about 20nA shutdown current.; Product description Function: 1.
