Configuring the device

The values configured in the advanced settings for the Ni cDAQ driver, seen below, stand for an estimate of the expected measurement values on each channel.
The controlled device uses these values to determine the best scaling and gain configurations internally in the hardware for the selected input channels.

Note. This means that the actual measured values returned from the device do not necessarily have to be within this specified range.
The actual measured values will eventually be determined by the internal hardware of the controlled device.
This can be different for each device depending on the installed module.
