where is inverse of equations 9-14a and
9-14b, T
ref
and V
x
are the current values read by the RH
and Temperature sensors and m
x
and other parameters
are the current calibration values for the sensor from
equations 9-14a, and 9-14b. After calculating
S
xnew
, the
new value is stored to memory.
Flow sensors zero
Resetting the zero setpoint on a flow sensor will alter
the offset parameter for a given sensor (
Z
flowx
in equa-
tions 9-17a and 9-17b). If you select the option to zero
the flow sensors, the software powers down the pump
and the blower before resetting the zero. The calibration
procedure will need the current zero parameters (
Z
x
from equations 9-17a and 9-17b) and current values for
the voltage reading on the flow sensor (
V
flowx
) with the
pump/blower OFF.
The calibration routine averages 10 seconds of data for
V
flowx
and then resets the zero:
9-38a
9-38b
After calculating Z
flowx
, the new value is stored to
memory:
