HT3540A and HT3540B Ultra Low-ohm DC Resistance Meter
Special for widely used in the field of meter resistance testing of copper poles in wires and cables
Overview
The HT3540B high-precision DC low resistance tester is specially launched by Hope Instrument to meet the ultra-low resistance test requirements in the industry of cables, materials, shunts, etc. It is featured in high precision and high stability and the minimum resolution of 0.01μΩ. HT3540B adopts low power consumption pulse forward and reverse current test mode, which greatly reduces the test error caused by the heat generated by the large current during the test.
Features
- Standard temperature compensation function
- Basic accuracy 0.02%
- Simultaneous display of resistance and resistivity
- 5 1/2display, minimum resolution 0.01μΩ, maximum reading300000
- Low-power pulse current test to reduce heat generation during test
- Ultra-low resistance testing requirements for cables, materials, shuntsindustries
- Forward and reverse current test mode to eliminate test errors caused by thermoelectric potential
- Special for CABLES, MATERIALS, SHUNTS,and other industries required Ultra-low resistance test application
- Using an external Pt resistor to preform temperature measurement
