The CVD20 provides 6 single-ended or six differential channels for connecting sensors that have a higher voltage output than what a datalogger can measure. The CVD20 contains resistors that divide the sensor's signal voltage by a factor of 20.
|Number of Channels||6 single-ended, 6 differential|
|Resistors||1 kohm and 19 kohm|
|Ratio Tolerance||±0.1% (@ 25°C)|
|Dimensions||9.4 x 6.9 x 3.8 cm (3.7 x 2.7 x 1.5 in.)|
|Weight||91 g (3 oz)|
Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
Each CVD20 can be wired to divide six differential or six single-ended voltage levels.
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).
