Example: The DAC output range selected is 0-5V (V
max
), the zero H
2
O value entered is 10
mmol/mol (X
Z
), the full scale H
2
O value entered is 60 mmol/mol (X
F
), and the measured out-
put voltage (V) is 2.9V. To calculate the H
2
O concentration from equation 3-4 above,
3-6
= 39.0 mmol/mol.
Converting Voltage Output to Cell Temperature
Cell temperature can be calculated from the DAC output voltage as follows:
3-7
where V is the measured voltage, X
F
is the full scale value for temperature output (entered in the
Settings Window as the 2.5 or 5V value, up to 100 °C), X
Z
is the zero value entered, and V
max
is
the full scale DAC output voltage selected (5V or 2.5V).
Converting Voltage Output to Cell Pressure
Cell pressure can be calculated from the DAC output voltage as follows:
