Serinus® 10 User Manual 3.2
Displays the state (On or Off) of the output pin and their corresponding
pin out on the analog & digital I/O port (refer to Figure 73), and allows
the user to manually set the state.
Note: Entering either the Digital Outputs Menu will temporarily disable all digital and analog
input/outputs. This will affect logging via these outputs. Exiting the menu restores automatic
control.
3.4.22 Calculation Factors Menu
Figure 51 – Calculation Factors Menu Screen
Main Menu → Service Menu → Calculation Factors Menu
The calculation factors within this menu provide the values used to calculate different aspects of
measurement and calibration.
A multiplication factor used to adjust the concentration
measurement to the appropriate level (set at calibration).
This field displays the offset created from a zero calibration. This is
the concentration measured from zero air and is subtracted from
all readings.
The correction factor calculated from the background cycle (used
to eliminate background interferences).
Displays the correction factor applied to the concentration
measurement. This correction is for changes in pressure,
temperature and flows since the last calibration.
The standard deviation of the concentration. The calculation is as
follows:
▪ Take a concentration value once every two minutes.
▪ Store 25 of these samples in a first in, last out buffer.
▪ Every two minutes, calculate the standard deviation of the
current 25 samples. This is a microprocessor-generated field
and cannot be set by the user.
This reading is only valid if zero air or a steady concentration of
span gas has been supplied to the instrument for at least one hour.
