The scope of use covers single and double arm bridges such as QJ23, QJ44, QJ57, etc., with digital measurement and built-in rechargeable lithium battery. 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.
● The instrument measurement range is 0～20kΩ
● Maximum output current 10A, suitable for extremely low resistance measurement of dry-type transformers
● Third-generation power technology, high efficiency, can test hundreds of transformers on a single charge
● Has inductive test piece anti-disconnection protection function, durable and reliable
● Has audible discharge alarm, clear discharge indication
