  QK200ALoop Resistance Tester with Printing has two measurement modes: traditional pulse mode and arc burning mode required by new standards. Pulse mode: single measurement or three consecutive measurements with automatic calculation of average value. Arc burning mode: default time is 15 seconds, 30 seconds, 60 seconds, and the measurement time can be selected between 0-60S according to actual measurement requirements.



 



Loop Resistance Tester with Printing Overview:



1. The test current is automatically stabilized without manual adjustment;



2. New anti-power frequency interference design ensures accurate measurement in strong power frequency interference environments;



3. Using potentiometer measurement principle, data is synchronously sampled at high speed, completely eliminating the influence of test current fluctuations on instrument accuracy;



4. Simple operation: just press the test button to obtain the measured loop resistance value and test current value;



5. The loop resistance value is automatically latched for easy viewing and recording;
