(1) Fast measurement speed: adopt advanced dual-power constant current source technology, advanced principles, high stability, can build test current quickly, its test speed is hundreds of times of the bridge.
  (2) Discharge quickly: Built-in fast discharge circuit, generally only takes a few seconds to complete the discharge, and can dynamically indicate discharge status, which effectively guarantee the personal and equipment safety.
  (3) Strong anti-interference: even under a serious disturbance in the environment, the last data can be stabilized at a word.
  (4) Safe to use: when test the DC resistance of load voltage regulating transformer, it can switch the tap switch position during the test, and will not cause equipment damage, safe and reliable.
