ESR Tester, High-Quality New Diode Transistor Capacitor SCR Inductor Tester, Multifunctional Industrial Measurement Instrument, Plastic Material, 36V Max Voltage, 0.1 Precision, Battery Powered, Non-Rechargeable 9V Battery

The FET's voltage must be lower than 5V when turned on or off. It features a 128*64 large Backlight LCD display, consuming only 2mA in standby mode when powered by a 9V battery (not included). Components include inductors, capacitors, diodes, dual diodes, MOS, transistors, SCRs, regulators, LED tubes, and ESR. It also has a resistance and an adjustable potentiometer. The resistance ranges from 0.1 ohm to a maximum of 50M ohm, while the capacitor ranges from 25pf to 100,000 uf, and the inductors range from 0.01mh to 20H.

Identifying NPN and PNP transistors, n-channel and p-channel MOSFETs, diodes (including dual diodes), thyristors, transistors, resistors, capacitors, and other components automatically. Testing the pins of a component automatically and displaying the results on the LCD screen. Capable of detecting the amplification coefficient of transistors, MOSFET protection diodes, and determining the forward biased voltage between the base and emitter of a transistor.

Determine the dimensions and capacitance of the MOSFET gate with respect to the threshold voltage Utilize a 12864 liquid crystal display featuring a green backlight

With just one click, the power will be turned off automatically. The shutdown current is as low as 20nA and it is compatible with battery operation. It can automatically identify PNP and NPN bipolar transistors, N and P channel MOSFETs, JFETs, diodes, dual diodes, and thyristors. Pin layout is automatically detected. It can also measure the current gain and threshold voltage of the emitter junction of a bipolar transistor.

Darlington transistors are distinguishable by their elevated threshold voltage and substantial current amplification factor.

The device can measure and display symbols for two resistors, showing up to four digits and units. The resistance symbol displayed indicates the probe numbers (1-3) connected at both ends. This allows for measuring potentiometers as well. When the potentiometer is adjusted to one end, the tester cannot differentiate between the pins in the middle and at the ends. The resistance measurement resolution is 0.1 ohms, with a maximum measurement value of 50M ohms.

Detect and measure capacitors, showing the top four digits and units. Capacitance values range from 25pF to 100mF, with a resolution of up to 1 pF. Measure ESR capacitance for capacitors above 10uF, with a resolution of 0.01 ohms and two-digit display. Display symbols correctly for two diodes, along with positive voltage drop.

The LED behaves like a diode, with a forward voltage drop significantly higher than usual. Two LEDs are recognized as two separate diodes.

If the reverse breakdown voltage is less than 4.5V, Zener diodes can be identified. Two diodes will be shown, and their anode can be distinguished by the voltage. If the symbols around the diode probe are identical, the true anode of the diode can be recognized by the threshold voltage close to 700mV.

If more than 3 diode type components are found, determine the quantity of diodes and show a different error message. This situation will only arise if the diode is connected to all three probes and at least one of them is a diode type. In such a scenario, connect only two probes and restart the measurement process one by one.

To determine the capacitance of a single diode, measure it in reverse. You can measure bipolar transistors by connecting the base to the collector or emitter. A single measurement is sufficient to identify the entire bridge connection. Capacitors with values lower than 25pf are typically not detectable, but can be connected in parallel with a diode or a capacitor of at least 25pf. In such cases, the parallel capacitance value must be subtracted.
