Calibration data
Specialist : System edit: Calibration data
This table is used to control the calibration conditions for the individual components.
There are two types of calibration:
• With span gas
• With internal Standard
Calibration with span gas
The calculated span gas concentration is compared with the entered nominal value for
span gas.
Discrepancies generate a calibration factor for span gas.
During measurement operation the measurement results are then corrected by the
calibration factor for span gas.
When calibrating with span gas the calibration factor for the internal standard is set to 1
again.
Calibration with internal calibration standard
The entered nominal value for the internal standard is multiplied by the calibration factor
for span gas.
Discrepancies with the nominal value generate a corrected internal calibration factor for
the internal standard.
During measurement operation the measurement results are then corrected by the
calibration factor for span gas as well as by the calibration factor for the internal standard.
Procedure
The following list was created to define the values displayed in this menu and explain, how
the program performs the correction of the measured values:
• Record measuring signal and reference signal
• Calculate absorbance
• Perform Zero correction
• Add Extra Offset
• Perform additive interference sensitivity correction
• Perform multiplicative interference sensitivity correction
• Linearization (e.g.: Calculation of absorbance into concentration, digits into analog
values, flow meter)
• Multiply by CALIBRATION factor
• Multiply by EXTRA factor
Settings
Component
i (= Ri) (i = 1..24) (not selectable)
The components corresponding to the results R1..R24 are selectable (at the
right) by <ENTER>. The components are automatically adopted from the list
out of Specialist: System edit: Results .
The measurement range is derived from Specialist: System edit: Signal output
As soon as you reach the field for the component O
2
, there is an automatic
switch-over to the menu containing the O
2
data (see below).
4 active IF Tables Enter number of interference table to be used for calculation. Max. 4 tables
can be specified.
0: Interference table is not used for calculation.
1 active LIN Table Enter number of linearization table to be used for calculation.
1: One table can be entered
0: No LIN table to be calculated
Span gas conc. Span gas concentration of the span gas connected (enter).
Internal standard: Nominal concentration of internal standard (enter)
