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 with a 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
- Minimum resolution 0.01μΩ, basic accuracy 0.02%
- Pulse current testing to significantly reduce heat generation during testing
- Standard temperature compensation function
- Simultaneous display of resistance and resistivity
- Forward and reverse current test mode to eliminate errors caused by thermoelectric potential
- TFT true color display (HT3540A: 3.5″, HT3540B: 4.3″)
Application
HT3540A and HT3540B are special for CABLES, MATERIALS, SHUNTS, and other industries requiring ultra-low resistance testing.
- Cables & Wires: Copper pole resistance testing
- Materials: Conductivity and resistivity evaluation
- Shunts: Precision resistance measurement for current shunts
- Batteries: ESR measurement on super capacitors and storage battery evaluation
- UPS: On-the-spot testing of uninterruptible power supplies
