Specificatii
GM328 Functional Transistor Tester Frequency Square Wave Generator LCD Diode Triode Capacitance ESR Meter for MOS/PNP/NPN L/C/R
Multi-functional transistor tester for automatic detection of
NPN and PNP transistors, N-channel and P-channel MOS FET, JFET,
diodes, dual diode, thyristor small power unidirectional and
bidirectional thyristor. Also can be used as square signal and PWM
signal generator.
Features:
Digital LCD backlight display for easy readings, can display
measured data and graphics.
Micro-controller uses 8MHz external crystal, the measurement
accuracy is better.
One key operation(long press the button and enter the menu
selection), automatic power shutdown.
Main chip is the DIP, easy for electronic enthusiasts to DIY or
update the main chip.
Can be powered by 9V battery(not included).
Can automatically detect NPN, PNP bipolar transistors, N-channel
and P-channel MOS FET, JFET, diodes, dual diode, thyristor small
power unidirectional and bidirectional thyristor.
Support 2 resistors measurement, also support potentiometer
measurement.
Resistance measurement resolution is 0.1 ohms, 50M ohms can be
measured.
Automatically test the pins of a component and show on the
display.
Measure the gate threshold voltage and gate capacitance of the
MOSFET.
Measure bipolar transistor current amplification factor and
base-emitter threshold voltage.
Can be used as signal generator and frequency meter: built-in
square signals from 1Hz-2MHz and can generate 1-99% PWM(pulse width
modulation) signals.
Notice:
Before measuring capacitance, the capacitor must be discharged,
otherwise very likely damage the meter.
Users need to add an interface with some components by themselves
if they want to measure the frequency(1Hz-2MHz)!
