ZERO ADJUST HISTORY
 Anytime the Zero Adjust values are changed, either manually by
the user or automatically by the system, the new Zero Adjust
values are stored in the Zero Adjust History archive with the
time, date, zero range and the zero type (calibration, check or
manual) information.
 The meaning of the codes used in the system for zero adjust are
as follows:
TOC-ZC: Zero calibration result for TOC.
TOC-ZK: Zero check result for TOC.
TOC-ZM: Manually input zero adjust value for
TOC.
TN-ZC: Zero calibration result for TN.
TN-ZK: Zero check result for TN.
TN-ZM: Manually input zero adjust values for
TN.
Span Program
SPAN PROGRAM 5
 SPAN PROGRAM defines the number of reactions to be carried
out for Span Calibration and Span Check cycles, which are
activated by RUN SPAN CALIBRATION/CHECK functions in
Span Calibration menu. If the Span Calibration or Span Check
is programmed as “YES” in New Regents Program menu,
START NEW REAGENT CYCLE function in Install New
Reagents menu will also run the relevant span cycle.
 The span calibration/check reactions are run at a single range
programmed by the RANGE below. Unless Span Adjust values
are modified manually in Span Calibration menu, system
calculates and uses the same Span Adjust values for the other
ranges if the span calibration cycle is completed without any
system warnings.
SPAN AVERAGE 3
 SPAN AVERAGE is the number of span reactions the system
averages to calculate the Span Adjust factors.
RANGE 1
 RANGE (1 by default) determines the range at which all Span
Calibration and Span Check reactions are carried out.

TIC STANDARD 200.0mgC/l
TOC STANDARD 100.0mgC/l
 TIC/TOC STANDARD defines the TIC/TOC standard solution
concentration levels (mgC/l) to be used in Span
Calibration/Check reactions.
 If TIC/TOC STANDARD is programmed as 0.0mgC/l, system
ignores the Span Calibration results and omits any related
warnings defined in TIC/TOC BAND below.
TIC BAND 25%
TOC BAND 25%
 TIC/TOC BAND determines the tolerance limits (25% by
default) for the Span Calibration or Span Check reaction results
for TIC/TOC.
 If the average span result is outside the tolerance limits, a
“30_TOC/31_TIC SPAN CAL FAIL” or “33_TOC/34_TIC SPAN
CHCK FAIL” warning is logged in the fault archives.
