Description
DC Resistance Meter features a high-performance ARM microprocessor control and high-density SMD placement process with 0.1% accuracy and a measurement range of 1μΩ to 30KΩ. The resistance value is displayed in 5 digits with 30000 readings. It is suitable for relay contact resistance, connector plug resistance, wire resistance, printed circuit board wiring and soldering hole resistance. AT516L comes standard with RS232 communication interface and supports SCPI protocol and Modbus protocol. Modbus has become the national standard GB/T19582-2008) applied to the automatic sorting system to complete the automatic pipeline test. It can be conveniently used for PLC communication control to realize automatic operation on the production line.
