Micro OHM Meters
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. HL- 100 is a direct reading tester, and uses a test current of 100A DC, resulting in true v alue and accur ate measurements.adopts digital circuit technique and is used for measuring contact resistance of switch control equipments at test current of 100A DC. The measurements are accurate as the test is highly stable.HL- 100 is a new, fully automatic micro controlled tester that measures contact resistance at 100A 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 Safety Features
• Fuse protection for line short circuit ORDERING INFORMATION HL- 100 Specification subject to change due to constant up gradation Description: NMC HL-100 is a new generation, fully automatic, 4 terminal line loop contact resistance tester. The entire test is done automatically and quickly. HL- 100 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 10 kg), single unit design housing the HL- 100. The HL- 100 is encased in an aluminum alloy cabinet. Features
