Set the optimum input/output range according to the input signal type (voltage, current) and the upper/lower limit of the signal.
For example, if the range is -10 to 10V with a 12-bit resolution device, the minimum unit of input is 20/4096, which is about 5 mV.
If the range is -5 to 5V, the minimum unit is about 2.5 mV, which means
that you can input with double precision.
Therefore, when the range of the used signal is within -5 to 5V, it is
better to set the range to -5 to 5V.
The input range setting depends on the devices.
1. Set by JUMPER on devices
2. Set by software
3. Set by JUMPER on device and software
Please refer to [Specifications based on devices] in function AioSetAiRange, AioSetAiRangeAll for setting the input range of your device.
When setting the range individually for each channel, use function AioSetAiRange.
When setting the range for all channels at the same time, use function
AioSetAiRangeAll.
