技术说明
CVD20提供了6个单端或6对差分通道，用于连接输出高直流电压的传感器。这些高直流电压不能被数据采集器直接测量。CVD20的电阻桥臂可将传感器的电压值降为原来的1/20。

Additional Compatibility Information
Data Logger Considerations
Each CVD20 can be wired to divide six differential or six single-ended voltage levels.
Programming
When using CRBasic, the CVD20 is measured with either the VoltSE or VoltDiff instruction. When using Edlog, the CVD20 is measured with either Instruction 1 (SE Volts) or Instruction 2 (DiffVolts).
