| | AT516 DC Resistance Tester is a benchtop instrument with fully automated real-time detection controlled by a high-performance ARM microprocessor. The instrument has an accuracy of 0.05% and a measurement range of 1μΩ~20MΩ. The resistance value is displayed in 5 bits with 30000 readings and a maximum sampling speed of 7ms. The instrument has built-in temperature compensation interface to compensate for errors due to temperature.
The instrument has built-in 14-step comparator output, which can set 10 qualified files, and all the comparator results can be output through the Handler interface.
The instrument comes standard with RS-232 interface, using SCPI (Standard Command for Programmable Instrument standard command set) and Modbus protocol (Modbus has become the national standard GB/T19582-2008) applied to automatic sorting system to complete automatic pipeline test. Communicate with computer, PLC or WINCE device to efficiently perform remote control and data acquisition functions. |
