The 4WPB500 uses two adjacent differential analog inputs. The first channel requires an adjacent analog ground channel to accept the "ground prong" of the 4WPB500. Not all data logger terminal strips have this sequence on all channels, so please check your data logger's wiring panel to confirm channel assignments, especially if you plan to use multiple terminal input modules.
Newer CR10X Wiring Panels and the CR10XTCR Thermocouple Cover are deep enough to cover the data logger input channels with a terminal input module attached; older CR10TCRs are not deep enough.
When using CRBasic, the 4WPB500 is measured with the BrHalf4W Instruction followed by the PRT Instruction. When using Edlog, the 4WPB500 is measured with Instruction 9 (Full Bridge w/ Measured Compensation) followed by Instruction 16 (Temperature RTD).
