source by the instrument. When performing a rEAd input as part of the
scaling process, the sensor must have the corresponding physical value
applied. This may be pressure, weight, temperature etc. The instrument
will sample the output from the sensor and save this as the L-ip and H-iP
scaling parameters.
A example of scaling: 0 - 100 mV = 0 -1000 (psi)
LdSP = 0 L-iP = 0 (mV)
HdSP = 1000 H-ip = 100.0 (mV)
