GDHL series adopt digital circuit technique and the switches circuit technique creation and is a special instrument used for the contact resistance measurement and

the line loop resistance measurement of switch control equipments. The test current adopts **0 A direct current recommended by the national standard GB**3 and can directly measure the line loop resistance or contact resistance under the circumstance of the **0 A,**0A,**0A,**0A,**0A or **0A current, and direct manifestation. It also can save **0 groups of data at most in the instrument and upload to PC through RS**2 interface. The instrument has accuracy measurement, stable function and is suitable for electric power and power supply sector to maintain high voltage switch on the spot and test the line loop resistance in the high voltage switch factory.
