Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
The 4WPB1K consumes two adjacent differential analog inputs; the first channel requires an adjacent analog ground channel to accept the "ground prong" of the 4WPB1K. 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 4WPB1K is measured with the BrHalf4W Instruction followed by the PRT Instruction. When using Edlog, the 4WPB1K is measured with Instruction 9 (Full Bridge w/ Measured Compensation) followed by Instruction 16 (Temperature RTD).

The 4WPB100, 4WPB1K, and 4WHB10K terminal input modules can be used instead of the 3WHB10K module. However, to maintain the enhanced accuracy of the four-wire half-bridge instruction, it is pertinent when adding the fourth wire to maintain the same resistance as the other three wires (same wire size and manufacturer). Note that simply adding a short jumper wire on the 4WPB100, 4WPB1K, or 4WHB10K modules to complete the fourth wire will not maintain the accuracy.
