Below is some model-specific information to help you locate your instrument response. The DAQ3-3, Sigma 3 and Sigma 4 datalogger models all use the TI ADS1282 Analog-To-Digital Converter and have the same responses. Each offers preamp gain options of x1 and x16, but digitized values are scaled by the inverse of this setting (and also scaled to output units of Volts) before samples exit the datalogger. Both preamp gain choices are listed below for clarity, but the instrument response does not vary based on preamp gain choice.
