ITEM NAME:Mega328 Transistor Tester LCR Capacitance ESR meter PWM TFT LCD Generator D J2F1 Mega328 Transistor Tester LCR Capacitance ESR meter PWM TFT LCD Generator D J2F1 The display unit using a 160x128 pixel color display, Rotary switch control, a key measurement, automatic shutdown. Use 9V laminated battery, can also use the power adapter(DC 6.8-12V), the whole current of about 30mA, after about 20nA shutdown current. Detecting power transistor and FET protection diodes built. Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pin out. Test NPN and PNP transistor common-emitter current amplification factor, the base - emitter threshold voltage, off the collector - emitter leakage current Function: Switch off; Transistor test; Frequency test; f-Generator; 10-bit PWM; C+ESR@TP1:3; continuous measurement resistance; 1-||-3 continuous measurement capacitance; Rotary encoder; SelfTest; Voltage test; FrontColor; BackColor adjust; Show date This item is DIY kits, need solder it by yourself. The use of SCM ATMEAG328P DIP-28. With IC Block. Pole through the transistor base - emitter threshold voltage and high current gain recognition Darlington transistor. About two seconds during the test, large capacitors and inductors will take longer. Additional features include a frequency measurement, voltage measurement, continuous testing, and other functions Test FET gate - source threshold voltage is turned on, the drain - source on-resistance, the gate - source capacitance. A maximum of two measuring resistors, so three feet adjustable resistor can be measured, if adjustable resistor is transferred to the end, can only be a measured resistance value. Output one fixed frequency, variable duty cycle pulse signal (PWM), the duty cycle is adjustable from 1% -99% Frequency range from 1Hz to 1MHz or higher, measured at frequencies below 25kHz, can display period resolution to 0.001mHz.
