programmed board configuration. The mV is generally ADC In but may also be
programmed to read amp In for certain applications.
5.1.3 Computation Method.
theoretical selection uses a lookup table value with linear extrapolation between
the table values. The calibrated mode uses a linear extrapolation based on two
user data points as described in the calibration computations section of this
document.

user is prompted to name the saved script which consists of a series of text
strings for each channel, defined in another section of this document. The saved
script is automatically given a “.txt” suffix unless one is provided.
