Out of stockDigital Multimeter Small Yellow Color LCD AC DC Measuring Voltage Current
[Measuring Instruments] A multimeter or a multitester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance. Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made. Digital multimeters (DMM, DVOM) display the measured value in numerals, and may also display a bar of a length proportional to the quantity being measured. Digital multimeters are now far more common than analog ones, but analog multimeters are still preferable in some cases, for example when monitoring a rapidly-varying As the name suggests it is the multifunction device for all your testing need for daily work. When testing DC voltage, AC voltage, DC current, resistance, diode, buzzer, and battery, connect the red test lead to “VΩmA” jack and black test lead to “COM” jack, whereas When you need to test the current more than 200mA, connect the red test lead to “‘ 10A≡” jack and black test lead to “COM” jack. And When while testing the temperature, connect the temperature probe to “VΩmA” jack or “COM” jack. When testing the magnifying ratio of the transistor, turn the switch to hFE position and connect the transistor to the eight hole jack available in blue color. For the Square wave output, the frequency is 50Hz, the voltage is approximately 3Vp-p. The output jack is “VΩmA” and “COM” Description Table: Features : Small size makes it comfortable in many areas Brand new product. Good for newbies with basic knowledge of VI.

In addition, the XT90 connector features a polarized design that prevents reverse polarity connection. As a result, it improves safety and protects connected batteries and electronic equipment from accidental wiring mistakes. Because of its robust construction, the connector can handle continuous currents up to 90A while maintaining a secure and stable electrical connection. Furthermore, the gold-plated contacts help reduce power loss and improve current transfer efficiency. The semicircular solder terminals simplify wire installation and support large wire sizes up to 8AWG, making the connector suitable for high-power applications. Moreover, the tight-fit design ensures a strong connection even in environments subject to vibration and movement. This XT90 connector set is widely used in RC aircraft, drones, electric scooters, e-bikes, battery packs, robotics systems, solar power projects, and DIY electronics applications. 🔹 Key Features High-current XT90 connector pair Gold-plated spring contacts High-temperature nylon housing Reverse polarity protection design Low resistance and high conductivity Supports up to 90A continuous current Accepts wire sizes up to 8AWG Easy soldering terminals Secure and vibration-resistant connection Includes protective cover caps 🔹 Technical Specifications Connector Type: XT90 Contact Material: Gold-Plated Brass Housing Material: High-Temperature Nylon Current Rating: 90A Continuous Peak Current: 120A+ (Short Duration) Voltage Rating: DC 500V Max Wire Compatibility: Up to 8AWG Polarity Protection: Yes Connection Type: Solder Type Color: Yellow 🔹 Applications This XT90 connector is suitable for: RC aircraft RC cars and boats FPV drones Electric bicycles (E-Bikes) Electric scooters Battery packs Solar energy systems Robotics projects High-current DC power systems 🔹 Package Includes 1 × XT90 Male Connector 1 × XT90 Female Connector 2 × Protective Cover Caps
