Detailed Description

The CVD20 provides 6 single-ended or six differential channels for connecting sensors that have a higher voltage output than what a data logger can measure. The CVD20 contains resistors that divide the sensor's signal voltage by a factor of 20.

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).
