Application Cases

• Using the PFT4A-2S-2P Data Acquisition Box to View Valve Opening/Closing Time Curves
• PT1000 Resistance-Temperature Table Query
• Example commands of the RTU module
• Querying Pulse Signal Frequency and Duty Cycle Using Software)

Engineering Issues

• When collecting 4-20mA analog signals, the sensor output is 4mA, but the module reading is less than 4mA. What could be the reason?
