General Information
HDHL Auto Contact Resistance Tester with advanced large power switch power technology and electric circuit is a special measurement instrument for testing the contact resistance of high/low switches, cable wires and welds. It can measure the resistance of test object under the standard current. The instrument is small size and light weight , which has the feature of strong anti-interference , high accuracy, easy operation and perfect protection function.
Features
- Color touch screen: 800X480 color 7inch touch screen and high speed thermal printer.
- Multi current class output
- Adopted the latest power technology, it can output continuously high current for long time with multi current class output. It can set 1-3 different current class for testing and automatically calculate average value.
- Display various data: Display resistance,voltage,current,resistivity and the converted resistance value at standard temperature.
- Auto over-limit alarm: Set the up-limit of resistance, qualified resistance value, over-limit or invalid, auto test status.
- Long time test. It can set measure time from 0 to 9999S and work for long time .Built-in cooling heat dissipation , auto heating protection for
- High accurate measurement: it adopts operational amplifier and high precision quadruple integral A/D converter for precision instrument.
