4.3 Temperature Sensor Calibration
1. Ensure blower motor is running
2.
Record the temperature displayed by the HiVol.
3.
Record the actual temperature with a certified precision thermometer. If
these measurements are significantly different, continue with the
calibration as follows:
4.
Calculate

Equation 2 Temperature coefficient calculation
5. Then:
Assign… …the value of…
Temp coeff 2 (Temp coeff 2) ÷ x
2
Temp coeff 1 (Temp coeff 1) ÷ x
Temp coeff 0 Do not change
6. Repeat steps 1-4 (if necessary) until the HiVol temperature is close to the
actual temperature.
4.4 Barometric Pressure Sensor Calibration
1. Record the barometric pressure displayed by the HiVol.
2.
Record the actual barometric pressure with a certified pressure gauge or
barometer. If these measurements are significantly different, continue
with the calibration as follows:
3.
Calculate the difference between the two values and adjust the barometric
pressure coefficient 0 (Pres. coeff0) by this value. If the HiVol is reading
high, decrease the value of the coefficient 0, and vice versa. Do not adjust
coefficient 1 (Pres. coeff1).
4.
Re-check the HiVol barometric pressure reading.
