Product Description
Introduction

DC resistance test instrument (YR type) is used to measure DC resistance of power & distribution transformers. It is also used for current transformers having high resistance values.  

Features:

  • Fast speed of charging, and charging voltage is up-to 30V.
  • Demagnetization function, and helps prevent the difficulty of power-on.
  • USB port to download test data to the USD flash disk.
  • Communicate with computer, with 485 communication port.
  • Offer protection, if tester is connected with AC power-supply of 380V.  
  •  Discharge alarming etc.
