ESR RLC Tester frequency counter GM328A on AtMEGA328P (ESR GM328A)
Description ESR RLC Tester frequency counter GM328A on AtMEGA328P
Color display 160*128 dots with color customization
The tester implements the functions
-Frequency counter up to 2MHz (input above display)
- Frequency generator and PWM generator (bottom output)
- Voltmeter (bottom input)
Allows you to measure:
- resistance - with resolution up to 0.1
- inductance
- ohmic resistance of inductance
- capacitor capacitance - resolution up to 1pF (starting from a certain capacitance, it shows ESR and voltage losses)
- determines the parameters of diodes, double diodes:
diode voltage drop measurement
diode parasitic capacitance measurement
pinout
LED characteristics
- determines the parameters of transistors:
type (NPN, PNP, N-P channel MOSFET JFET)
measurement of the current transfer coefficient of the base of bipolar transistors
determining the saturation voltage of a bipolar transistor
FET gate capacitance measurement
determination of the opening voltage of a field-effect transistor
indicates the presence of a protective diode
pinout
- determines the pinout of thyristors, triacs
- voltage measurement on batteries
Ranges:
