Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
The 4WHB10K uses two sequential differential analog inputs; the first differential channel must have an adjacent analog ground channel to accept the "ground prong" of the 4WHB10K. 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.
The 4WHB10K is measured either with CRBasic's BrHalf4W Instruction or Edlog's Instruction 9 (Full-Bridge with Excitation Compensation).

For more information, refer to Figure 3-1 in the "Wiring" section of the 4WPB100, 4WPB1K PRT Bridge Terminal Input Modules Instruction Manual.
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.
