Contact Resistance Tester also known as circuit resistance tester. Circuit resistance measurement is an important part of the electrical test. we developed the new generation of Contact Resistance Tester according to the standard DL/T845.4-2004 of “Chinese Electric Power Industry Standard”, and refer to the requirement of “Resistance Measurement Equipment General Technical Conditions Part 4: Circuit Resistance Tester”. It can easily measure the contact resistance of high and low voltage switch main contact, also can conveniently test DC resistance of high and low voltage cable and other pure resistance tested products.
Overview
Characteristics and functions
(1) This product is adopted with high precision and high stability of DC constant current source can supply fix DC current output overcome the shortcomings that traditional circuit resistance tester needs to adjust the output current;
(2) This product uses the LCD display which has a wide temperate with backlit large screen graphic rather than the traditional digital tube display. It can visually display test data making the operation more convenient and concise;
(3) This product uses the operational amplifier applied in precision instruments and high precision A/D converter combined with high performance 16 bit single-chip to ensure the testing accuracy of the product.
(4) This product is designed a real-time calendar clock data storage printing and protection functions etc which make the product function more complete and more cost-effective.
