Product Description

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

1. Color touch screen: 800X480 color 7inch touch screen and high speed thermal printer.
2. Multi current class output
3. 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.
4. Display various data: Display resistance,voltage,current,resistivity and the converted resistance value at standard temperature.
5. Auto over-limit alarm: Set the up-limit of resistance, qualified resistance value, over-limit or invalid, auto test status.
6. 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
7. High accurate measurement: it adopts operational amplifier and high precision quadruple integral A/D converter for precision instrument.
8. Latest system chip: high performance 32 bit latest ARM chip. System can automatically switch magnification times according to the signal to ensure the measurement accuracy .
9. Built-in Calendar - Clock
10. DC constant current source function: it can output 0-1000A built in increasing current system step by step , which is equal to a powerful DC constant current source.
11. Large measurement data storage .
