Transformer DC resistance testerNot only suitable for measuring inductive samples such as transformers, transformers, and reactors, but also for measuring resistive samples such as copper bars, wires, and switch contacts. The instrument testing speed is fast and the accuracy is high.
Features:
Powered by lithium batteries or 220V AC power, it is adaptive and can continuously test the DC resistance of hundreds of transformers on a single charge. The testing process is simple and convenient.
Output six levels of current, 10A current, 25V voltage, and can automatically select current for convenience and speed.
Wide range and high accuracy, 500u Ω~50K Ω.
Equipped with resistance temperature conversion function and optional wireless temperature measurement module, it can measure the temperature of the on-site test sample in real time to ensure the accuracy of the resistance conversion value.
It has multiple protection functions such as back electromotive force protection, wire breakage protection, power-off protection, and overheating alarm.
The 5.6-inch ultra large industrial grade high brightness color LCD screen displays clearly and visibly even in strong sunlight.
Equipped with an external printer for easy data printing.
It has both local storage and USB storage.
Notes:
Please turn off the power of the instrument in a timely manner when it is not in use.
If the instrument is not used for a long time, please charge and discharge it regularly, and the battery should be charged and discharged at least once a month.
It is strictly prohibited to use the instrument with low power. Low power will seriously shorten the battery life and even cause the battery to be scrapped. When the instrument is under powered, the power should be immediately turned off and charged. To avoid battery failure caused by prolonged discharge time.
Charging light: The charging light on the charger lights up red during the charging process; After charging is completed, it lights up green.
Users are not allowed to disassemble the instrument and replace the battery without authorization. If the instrument or battery malfunctions, please return it to the factory for handling.
