Product description:

3.7V Inductor Capacitor ESR Meter Transistor Tester DIY MG328 Multifunction Tester

Product parameter:

Instrument power supply: 3.7V power supply or direct power supply via micro USB interface

◆Using ATmega328 microcontroller.

◆12864 graphic LCD display test results.

◆One-key operation automatically turns off the power.

◆Exclusively increase the power switch to avoid battery consumption during storage and shutdown.

◆Automatically detect PNP and NPN bipolar transistors, N and P channel MOSFETs, JFET field-effect transistors, diodes, double diodes, SCRs, resistors, capacitors, and inductors. Automatically detect pin definitions.

◆Measure the current amplification factor (B) of the bipolar transistor and the conduction voltage (Uf) of the emitter junction. Darlington transistors can be identified by high threshold voltage and high current amplification factors.

◆The protection diodes inside bipolar transistors and MOSFETs can be detected and displayed on the screen.

◆Measure the threshold voltage and gate capacitance of MOSFET.

◆Support the measurement of two resistances, and the potentiometer can also be measured. If the potentiometer is adjusted to one end of it, the tester cannot distinguish the pins in the middle and both ends.

◆The resolution of resistance measurement is 0.1 ohm, and the highest measurement value is 50M ohm.

◆The capacitance measurement range is from 25pf to 100mF (100,000 UF). The resolution can reach 1 pF, and the inductance measurement range is 0.01MH-20H, otherwise, it will be displayed as a resistance. If the DC resistance of the inductor is higher than 2100 ohms, it will also be displayed as resistance.

◆It can detect the equivalent series resistance (ESR) of capacitors above 2UF with a resolution of 0.01 ohm. This function is very important for detecting capacitance performance.

◆It can display the symbol of the correct direction for two diodes, and display the forward voltage drop at the same time.

◆The LED is detected as a diode, and the forward voltage drop is higher than the normal value. The dual light-emitting diodes are detected as dual diodes. The light-emitting diode will flash during detection.

◆The time for each test is about two seconds, only the large capacitance and inductance measurement will take a long time.

Correction method:

Short connect the three test terminals and enter the test. The screen prompts the calibration steps.

1. When prompted to disconnect the short connect, disconnect the three test terminals and the calibration will continue;

2. When prompted to connect a capacitor of more than 100nF to pins 1-3, please connect a non-polarized capacitor of more than 100nF, and the program will automatically enter the next step. Until the end of the correction to restart, can complete the correction.

Note: When installing the battery for the first time, you need to activate the battery.

Method 1: After installing the battery, use tweezers or a short wire to short the two holes.

Method 2: After installing the battery, plug in the charger to complete the activation.
