HT3544 DC Resistance Tester
Suitable for use in complex scenarios with ATE for precise testing, available multiple channels
Overview
HT3544 DC Resistance Tester offers test range 0.1uΩ~3MΩ and basic accuracy ±0.02%rdg. ±2dgt, the minimum resolution is 0.1uΩ. It has comparator judgment binning function.
Equipped with RS232C/RS485, LAN I/O output port and temperature test interface, HT3544 tester is suitable for product testing and measurement for both manual and automatic production line.
HT3544 DC resistance tester production standard is complied with IEC61010 safety standards.
The HT3544 series tester adopts the four-wire test principle, high precision, low temperature drift, and highly integrated chip control loop design, which makes it more excellent, accurate and stable in low resistance level measurement.
HT3544 tester has 3 type of interfaces RS232/RS485/LAN and supports SCPI protocol. Users can efficiently complete remote control and data acquisition as well as instrument networking.
- Benchtop HT3544 with compact structure
- Anti-interference design, suitable for complex occasions in electromagnetic environment
- Fast and high-precision testing, rich interfaces
- Rich interfaces configuration easy for system integration
- Maximum 70V charged protection function, effectively avoid unintentional charged test damage to the main unit
