Graphic M8 Transistor Tester Diode Inductance Capacitance ESR Voltage Frequency Meter with Case

Graphic M8 Transistor Tester Diode Inductance Capacitance ESR Voltage Frequency Meter with Case

Features:
-Built-in 3.7V lithium battery.
-The 12864 graphic LCD displays the test results.
-One-button operation, automatically turn off the power, added power switch to avoid battery consumption during storage and shutdown.
-Automatic detection of PNP and NPN bipolar transistors, N and P channel MOSFET, JFET, diode, double diode, thyristor, resistor, capacitor, and inductor. Automatically detect pin definition.
-It can measure the current amplification factor (B) of bipolar transistors, lower power Darlington crystals and the threshold voltage (Uf) of the emitter junction.
-The protection diodes inside bipolar transistors and MOSFETs can be detected and displayed on the screen.
-It can measure the threshold voltage and gate capacitance of MOSFET.
-It supports dual resistance measurement and potentiometer measurement. If the potentiometer is adjusted to the end of a certain end, the tester cannot distinguish the middle and both ends of the pin.
-The resolution of the test resistance is 0.1Ω, and the maximum is 50MΩ.
-The measurement range of capacitance is from 25pF to 100mF (100,000 Uf), and the resolution can reach 1pF. It can detect the equivalent series resistance (ESR) of capacitors above 2UF with a resolution of 0.01Ω. This function is very important for detecting capacitance performance!
-The inductance measurement range is 0.01mH-20H, otherwise it will be displayed as resistance; DC resistance higher than 2100Ω will also be displayed as resistance.
-You can test dual diodes, and display the correct direction and forward voltage drop after the test.
-The LED is detected as a diode, and the dual light-emitting diode is detected as a double diode. -The light-emitting diode will flicker during the test.
-Each test time is about 2 seconds, but large capacitance and inductance measurements will take a long time.

Correction Method:
Short-circuit the three test terminals, enter the test, the screen prompts the calibration steps. When prompted to disconnect and short-circuit the three test terminals, the calibration will continue. When prompted to connect a capacitor of 100nF or more to pin 1-3, the program will automatically enter the next step after connecting a non-polarized capacitor of 100nF or more. The calibration can be completed by restarting until the calibration is over.

Package List:
1 x M8 Transistor Tester

Note:
-Before testing the device, the device must be fully discharged, otherwise the meter may be damaged.
-If you are testing devices with high capacitance, inductance, and conduction voltage drop, it is recommended to test on the test interface of the tester. Try not to use the test cable to test, so as to avoid large errors caused by the resistance of the test cable.
-Turn on the power switch of the tester, the LCD screen will not light up; press the test button (TEST key), and the LCD screen will light up.
-The tester is not suitable for applications that require high measurement accuracy.
-Measurable components: various diodes, capacitors, resistors, triodes, thyristors, MOS tubes, etc.
-It can only be used to measure electronic devices, not power devices (high-power mos, thyristors, etc.).
-The meter has been calibrated before leaving the factory, users do not need to calibrate by themselves, it can be used directly.
