Minimizing errors in multiplexed 3-wire RTD data acquisition systems

Overview:
The Resistance Temperature Detector (RTD) monitors temperature in many industrial applications. In a distributed control system (DCS) or programmable logic controller (PLC), a data acquisition module can be used to monitor many RTD temperatures installed remotely. In high-p

The correct use of the multimeter?

Depending on the size of the electrolytic capacitor, the R×10, R×100, and R×1K blocks of the multimeter are usually used for testing and judgment. The red and black test leads are respectively connected to the negative pole of the capacitor (the capacitor needs to be discharged
