4.-6. TIC Span Adjust.
This menu item allows the user to set the TIC span adjust factors manually for each
range as described for TOC Span Adjust above.
10. Run Span Calibration.
This function starts the Span Calibration cycle. The span calibration reactions are
run at a single range programmed by the RANGE in this menu below. At the end of the span calibration
cycle, BioTector automatically calculates the Span Adjust factors and displays it for Span Adjusts above.
Unless it is manually modified, the same Span Adjust factor calculated for the programmed RANGE in
this menu is used for the other two ranges as well. The span reactions operates in the same manner as a
normal reaction, but the Sample Pump reverse operation is disabled to prevent the contamination of the
standard solution connected to calibration/manual port. Span Calibration reactions have the prefix of
“SC”.
11. Run Span Check.
This function starts the Span Check cycle. The operation is similar to the Span
Calibration cycle above, but BioTector does not update any Span Adjust values at the end of the span
check cycle. Span Check reactions have the prefix “SK”.
13. Span Program.
Span Program
function allows the user to program the number of span reactions to be
carried out during the Span Calibration and Span Check cycles. It is recommended not to modify the
factory set Span Program value unless it is absolutely necessary. Any unnecessary modification in this
setting may have an impact on the span adjust values.
14. Span Average.
Span Average function allows the user to program the number of reactions to be
averaged at the end of the Span Calibration and Span Check cycles. It is recommended not to modify the
factory set Span Program value unless it is absolutely necessary. Any unnecessary modification in this
setting may have an impact on the span adjust values.
15. Range.
Range function allows the user to program the operation range at which the Span Calibration and
Span Check reactions are carried out. If the selected range is in conflict with the programmed
CALIBRATION STANDARD concentration in this menu, system automatically displays a “Caution!
Reaction range or Standard is Incorrect” warning. See System Range Data screen (see Section
for details) in order to select the correct operation range or correct
standard solution.
16. TOC Cal Std.
TOC Calibration Standard function allows the user to program the concentration (mgC/l) of
the TOC standard solution used in Span Calibration reactions. If the programmed concentration level is in
conflict with the programmed RANGE above, system automatically displays a “Caution! Reaction Range
or Standard is Incorrect” warning. See System Range Data screen in order to select the correct operation
range or correct standard solution. If TOC Calibration Standard is programmed as 0.0mgC/l, system does
not calculate or update any Span Adjust factors and therefore omits any span related warnings defined
above. See Section
6.2
Calibration Standards
for the details of BioTector standard solutions and
preparation procedures. In TC systems, this parameter is named as TC Calibration Standard.
17. TOC Check Std.
TOC Check Standard function allows the user to program the concentration (mgC/l) of
the TOC standard solution used in Span Check reactions. If TOC Check Standard is programmed as
0.0mgC/l, any span related warnings are omitted. In TC systems, this parameter is named as TC Check
Standard.
18. TIC Cal Std.
TIC Calibration Standard function allows the user to program the concentration (mgC/l) of
the TIC standard solution used in Span Calibration reactions. If TIC Calibration Standard is programmed
as 0.0mgC/l, any span related warnings are omitted. In VOC and TC – TIC systems, it is recommended to
run the TIC and TOC calibrations separately using separate standard solutions.
19. TIC Check Std.
TIC Check Standard function allows the user to program the concentration (mgC/l) of the
TIC standard solution used in Span Check reactions. If TIC Check Standard is programmed as 0.0mgC/l,
any span related warnings are omitted.
