Project Description
Product Features:
Lithium battery power supply or 220V AC power supply is self-adaptive, and it can continuously perform DC resistance test of hundreds of transformers on a single charge. The test process is simple and convenient.
Output six gears of current, the maximum output current is 10A, the maximum output voltage is 25V, and the current can be automatically selected, which is convenient and quick.
Wide range, high precision, 500uΩ～50KΩ.It has a resistance temperature conversion function, and an optional wireless temperature measurement module can be used to measure the temperature of the test sample in real time to ensure the accuracy of the resistance conversion value.With local storage and USB storage, it is convenient for data storage.
The handheld transformer DC resistance test is an innovative product. The product is small in size, hand-held operation, lighter and easier to carry.
The product is not only suitable for the measurement of inductive samples such as transformers, transformers, and reactors, but also suitable for the measurement of resistive samples such as copper bars, wires, and switch contacts.
The instrument has fast test speed and high accuracy.
It has a resistance temperature conversion function, and an optional wireless temperature measurement module can be used to measure the temperature of the test sample in real time to ensure the accuracy of the resistance conversion value.
It has multiple protection functions such as back-EMF protection, disconnection protection, power-off protection, overheating alarm and so on.
The 5.6-inch large industrial-grade high-brightness color LCD screen can still be clearly visible under strong sunlight.
Equipped with an external printer for easy data printing.
With local storage and USB storage.
