SYSTEM PROGRAM 2
SYSTEM PROGRAM 2 TIC + TOC
RANGE CHANGE 1-2 50.0mgC/l  RANGE CHANGE 1-2 defines the concentration levels for the
BioTector to change its range automatically from range 1 to
range 2.

The RANGE CHANGE 1-2 is typically the top concentration
point of TOC RANGE 1 in System Range Data menu by default.
RANGE CHANGE 1-3 150.0mgC/l  RANGE CHANGE 1-3 specifies the concentration level for the
BioTector to change its range automatically from range 1 to
range 3.

The RANGE CHANGE 1-3 is typically 50-75% of the top
concentration point of TOC RANGE 2 in System Range Data
menu by default.
RANGE CHANGE 2-1 40.0mgC/l  RANGE CHANGE 2-1 states the concentration level for the
BioTector to change its range automatically from range 2 to
range 1.

The RANGE CHANGE 2-1 is typically 20% less of the top
concentration point of TOC RANGE 1 in System Range Data
menu by default.
SAMPLE IN 5p P-V
 SAMPLE IN identifies the amount of sample (in pulses) to be
injected into the reactor at range 2.
TIC ACID 12p

TIC ACID defines the amount of acid reagent (in pulses) to be
injected into the reactor at range 2.
BASE 70p

BASE specifies the amount of base (in pulses) to be injected into
the reactor for the BASE OXIDATION phase at range 2.
BASE OXIDATION 130s 
BASE OXIDATION defines the oxidation time (150s by default),
which can be programmed independently for range 2.
 If the Base Oxidation time is different than the one programmed
in System Program 1 menu, depending on the difference
between the two settings, the reaction time at range 2 will be
either longer or shorter than the reaction time displayed in
System Program 1 menu.
TOC ACID 58p 
TOC ACID states the amount of acid (in pulses) to be injected
into the reactor for the TOC SPARGE phase at range 2.
