Specification:
Color: as picture shows
This item is DIY kits, need solder it by yourself
The use of SCM ATMEAG328P DIP-28. With IC Block
The display unit using a 160x128 pixel color display, full-screen characters 8x20, 16-bit color depth, graphic display element symbols
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
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
Pole through the transistor base - emitter threshold voltage and high current gain recognition Darlington transistor
Detecting power transistor and FET protection diodes built
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
Resistance measurement maximum resolution 0.01Ω. Can be measured up to 50MΩ
Capacitor measuring range from 25pF-100mF, Resolution 1pF
Larger than 90nF capacitor while measuring its equivalent series resistance (), the equivalent series resistance of the highest resolution of 0.01Ω
Larger than 5000pF capacitor also showed the rate of decline after the charging voltage of the capacitor value can reflect the quality factor (Q value)
Measuring a maximum of two diodes show its positive and negative, on-state voltage LEDs also display a graphic symbol diode, the conduction voltage is much higher than ordinary diode
Reverse breakdown voltage is lower than 4.5V Zener di
