CVD20 20:1 Voltage Divider 1. Introduction The CVD20 provides six single-ended or six differential channels for connecting sensors that have a higher voltage output than what a datalogger can measure. Resistors in the CVD20 divide the sensor's signal voltage by a factor of 20. 2. Cautionary Statements The CVD20 is rugged, but it should be handled as a precision scientific instrument. 3. Initial Inspection Upon receipt of the CVD20, inspect the packaging and contents for damage.
CVD20 20:1 Voltage Divider 1). A two-foot length should be sufficient if the datalogger and CVD20 are housed in the same enclosure. TABLE 1.

CVD20 20:1 Voltage Divider The multiplier to use with the voltage measurement must take into account the divisor, the calibration of the sensor, and the units desired for the result. 6.1 Examples Suppose the user wants to measure a sensor with a 0 to 5 V output. Using the CVD20 20:1 voltage divider, the 5 volt output will be divided to 5/20 = 0.25 V or 250 mV.
