技术说明
4WFBS1K 是一个4线全桥桥臂模块。可用来组成一个全单臂电桥，亦可用来组成后半段单臂电桥。数据采集器可以测量出电桥电路为输出电压增加阻抗而产生的微小的变化。
4WFBS1K 包括2个外部的针，用于分路校正，通常被用来校正比较微弱的误差。

Additional Compatibility Information
Multiplexers
The 4WFBS1K is compatible with our multiplexers.
Data Logger Considerations
The 4WFBS1K uses one differential analog input; an adjacent analog ground channel accepts the "ground prong" of the 4WFBS1K. 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.
The lead wire that emanates from the head of the 4WFBS1K connects to a data logger excitation channel.
Please note that if a CR10X will be used to measure thermocouples in the same application, newer CR10X Wiring Panels and the CR10XTCR Reference Thermistor (with its accompanying Thermocouple Cover) are deep enough to cover the data logger input channels with a Terminal Input Module attached; older CR10TCRs are not deep enough.
Programming
The 4WFBS1K is measured with the BrFull Instruction in CRBasic, and with Instruction 6 (Full Bridge) in Edlog.
