Product Description

Introduction:  Measuring  the line loop contact resistance by bridges is not  the  ideal  method  as  the  test current is only a few milli amperes. Thus the value is not the true value of the contact resistance. Model HL- 200 is a direct reading tester, and uses a test current of 200A DC, resulting in true value and accur ate measurements. Model  HL- 200 adopts digital circuit technique and is used   for   measuring contact resistance of switch control equipments at test current of 200A DC. The measurements are accurate as the test is highly stable.HL- 200  is  a  new,  fully  automatic micro controlled tester that measures contact resistance at 200A DC with built in printer.

The advantages of HL-100
• Automatic measure of contact resistance in 3 seconds
• True 4 terminal measurement: High accuracy. No lead compensation required
• Test results saved automatically
• Recall and print last 100 test results
• Prints results on built-in printer

Description:    NMC HL-200 is a new generation,fully   automatic,
4 terminal line loop contact resistance tester.   The   entire   test   is   done automatically  and  quickly.  HL- 200 takes  over;  powers  up  the  test current,  takes  the  readings  and displays  the  results  on  the  LCD screen. Prints test results through its built-in printer. Test results can be saved in memory and can be recalled later. True portability is achieved by the lightweight (only 12 kg), single unit design housing the HL- 200. The HL- 200 is encased in an aluminum alloy cabinet.
