NI 9203 Calibration Data
The NI 9203 has eight channels each with two modes. Each channel can
have a nominal unipolar input range of 0–20 mA or bipolar ±20 mA. Each
channel has an associated LSB weight, which is the number of amps per bit,
and an offset, which is the number of amps per bit measured when the
inputs are open.
Note LSB weight is referred to as Gain in the object dictionary.
The difference in offset from channel to channel is negligible.
The calibration data gives one offset and eight gains for each mode, a total
of 2 offsets and 16 gains in total. All channels in a given mode use the same
offset. The host can then take these constants and adjust the raw data into
calibrated data.
