Correction Factor for Current. Adjusts the
scaling of the sense resistor current
measurements. Used to calibrate the
measurement of current at the RSHP and
RSHN input pins. This is set for the size of
the current sense resistor.
Correction Factor for Temperature. Adjusts
the scaling of temperature measured
across an external thermistor at the V
input pin.
Correction Factor for Temperature. Adjusts
the scaling of temperature measured from
the internal temperature sensor.
Calibration: New CF_TEMP = Old
CF_TEMP x (Thermometer[ C] / SBData
Temperature[°C] )
Note: SBData Temperature is reported in
0.1 K normally. It must be converted to C
for this equation.
