The JY44B DC Resistance Bridge covers the scope of single and double arm bridges such as QJ23, QJ44, QJ57, with digital measurement and built-in rechargeable lithium battery. It is suitable for DC resistance measurement of transformers up to 35kV and all instrument transformers; it can also be used for DC resistance measurement of metal conductors, switches, motors, etc. The instrument is compact and lightweight, making it an ideal tool for power generation, power supply, and industrial and mining enterprises.
Function Introduction
● The measurement range of the instrument is 0~20kΩ
● Maximum output current 10A, suitable for extremely low resistance measurement of dry-type transformers
● Third-generation power technology, high efficiency, one charge can test hundreds of transformers
● Has inductive test object anti-disconnection protection function, durable and reliable
● Has audible discharge alarm, clear discharge indication
