NegativeLoad DC Resistance Rapid Tester Main Features
Inductive Load DC Resistance Rapid Tester adopts high-speed A/D converter and programmable current source technology, achieving excellent measurement results and highly automated measurement functions. It is a portable instrument used to measure various low-value resistances, especially low-value resistances of inductive loads. It features high accuracy, wide measurement range, stable data, good repeatability, strong anti-interference capability, complete protection functions, and fast charge/discharge speed. It is specially used to measure the DC resistance of inductive equipment such as transformers, motors, and mutual inductors. The DC resistance test of transformer windings is an essential test item after transformer handover, major repair, or tap changer change. In general, using traditional methods (bridge method and voltage drop method) to measure the DC resistance of transformer windings and high-power inductive equipment is a time-consuming and labor-intensive task.
Inductive Load DC Resistance Rapid Tester main features:
1. Uses imported components and a high-speed 16-bit A/D converter, ensuring stable measurement data, high accuracy, and good repeatability.
2. Built-in rechargeable battery pack, no AC power supply needed for field testing, resistance measurement range of 1μΩ-2KΩ, wide range, and convenient use.
3. LCD display mode, adaptable to various working environments, can display measurement current and measurement time. Intelligent power management technology effectively reduces internal heat generation.
4. Automatic programmable current source technology, with 1000 current levels set by the internal microcontroller based on the measured resistance, achieving a wider measurement range and optimal measurement state without manual current range switching.
5. Highly intelligent design, can automatically detect faults such as loose test leads or broken wires.
6. Complete protection functions, reliably protect the instrument from back EMF impact, with automatic discharge indication. Can store 120 measurement data, not lost on power failure. All Chinese menu and operation prompts, intuitive and convenient.
Inductive Load DC Resistance Rapid Tester precautions
1. After using the DC power supply for testing, the internal battery should be charged and maintained promptly.
2. During DC testing, if the undervoltage indicator light is on, stop using the DC power supply and switch to AC power for testing.
3. When the instrument is not used for a long time, the internal battery pack should be charged and maintained regularly (every two months), generally charging for about 14 hours until the "Fully Charged" indicator light is on.
4. The instrument should be protected from moisture, dropping, and prolonged sun exposure.
