Screen Size: 3.7 * 3cm / 1.45 * 1.18in
Display: 160*128 LCD
Automatic shutdown, shutdown current is only about 20nA.
Measure FET gate threshold voltage and gate capacitance.
Package Weight: 69g / 2.45oz
Use 9V battery (not included), can also use DC power (DC 6.8-12V).
Digital LCD display for easy readings, can display measured data and graphics.
Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.
Product Weight: 66g / 2.3oz
Capacitance Resolution: 1pF
Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout.
Specifications:
Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.
Support 2 resistors measurement, show its positive and negative, on-state voltage.
Can be used as signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM (pulse width modulation) signals.
Current: Approx. 30mA
Capacitance Measurement: 25pF~100mF
Multi-functional transistor tester for automatic detection of NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout. It also can be used as square signal and PWM signal generator.
Notice:
Rotary switch control, a key measurement for convenient use.
Features:
Automatically test the pins of a component and show on the display.
Test NPN and PNP transistor common-emitter current amplification factor, the base-emitter threshold voltage, off the collector - emitter leakage current.
Power Supply: 1 * 9V Battery (not included); DC 6.8-12V
