Product Description Polish seller! Microprocessor electronic component tester M328 Application: The device is used to quickly check many types of electronic components such as resistors, capacitors, transistors, triacs, coils, diodes, zener diodes. The tester automatically detects the type and pinout of the connected element and displays the measured parameters of the tested element. Functionality: The tested element is connected freely under the available leads (1-2-3), recognition, and measurement begins at the push of a button. Before measuring the capacitance, the tested capacitors should be unloaded, by shorting the pins of the element. Instructions: An unknown element should be placed in the stand so that the pins of the elements are in columns of different numbering. Then press the button - tester automatically recognizes what element was placed and its parameters. Column No. "1" is duplicated to facilitate testing of larger-sized components. Attention! Before measuring the capacitance, the tested capacitors should be unloaded, by shorting the pins of the element. The stand is in a battery container. Type of tested elements and checked parameters: Capacity measurement: 25pF - 100 000uF Resistance measurement: 0,5Ohm to 50MOhm Inductance: 0.01mH - 20H Transistors: NPN, PNP (hFE, Uf) MOSFET transistors: gate threshold voltage and capacity Transistors JFET: Vgs, I ESR measurement for capacitors above 25uF Tyristors, triacs: resistance test Display: LCD 1.8" Power supply: 9V battery
