50.0mgN/l  TN
concentration level (mgN/l) to be used in Span Calibration or
Span Check reactions.
 If TN STANDARD is programmed as 0.0mg/l, system ignores
the Span Calibration or Span Check results and omits any
related warnings defined in TN BAND below.
25%
 TN BAND states the tolerance limits (25% by default) for the
Span Calibration or Span Check reaction results.
 If the average span result is outside the tolerance limits, a
"36_TN SPAN CAL FAIL" or "39_TN SPAN CHCK FAIL" warning
is logged.
 Anytime the Span Adjust value is changed, either manually by
the user or automatically by the system, the new Span Adjust
factors are stored in the Span Adjust History archive with the
time, date, span RANGE, span type (calibration or check) and
the standard solution information.
 The meaning of the codes used in the system for span adjust
are as follows:
 ACID&BASE PURGE defines the total operation time (in
150s
seconds) of the Acid & Base Reagent Pumps and if installed HCl
Water Pump to prime the oxidation phase reagents (Acid, Base
and HCl Water solution) during the Install New Reagent cycle.
33p , 15s  TN CLEANING and DI WATER PURGE functions specify the
42p , 20s
system pump operation times (programmed by the number of
pulses) to prime the liquid phase reagents (TN Cleaning Solution
and DI Water) during the Install New Reagent cycle.
 The reagent purge is activated by START NEW REAGENT
CYCLE function in Install New Reagents menu or alternatively
by RUN REAGENTS PURGE function in Zero Calibration menu.
STANDARD specifies the
TIC/TOC-SC: Span calibration result for TIC/TOC.
TIC/TOC-SK: Span check result for TIC/TOC.
TIC/TOC-SM: Manually input
TIC/TOC.
TN-SC: Span calibration result for TN.
TN-SK: Span check result for TN.
TN-SM: Manually input span adjust for TN.
