SYSTEM PROGRAM 2 TCe
SAMPLE IN 2p , P-V

SAMPLE IN defines the amount of sample (in pulses) to be
injected into the reactor in TC mode at range 2.
8.3.3 Calibration Data
DECIMAL PLACES 3 
DECIMAL PLACES setting defines the number of decimal
places (0, 1, 2 or 3) system displays in the reaction results and
in the relevant system menus.

The default unit for reaction results is mg/l “milligrams per liter”.
Depending on application requirements and preferences, it is
possible to configure the system to display the results in ppm
“parts per million”, in µg/l “micrograms per liter” or in ppb “parts
per billion”. For further information, contact your local distributor
or the manufacturer.
TOC/TC CALIBRATION 1
TOC/TC CALIBRATION 2
TOC/TC CALIBRATION 3
TIC CALIBRATION 1
TIC CALIBRATION 2
TIC CALIBRATION 3

Calibration menus are used to install the calibration data and
thus to calibrate the BioTector in factory. TOC CALIBRATION 1,
2 and 3 shows the calibration curves for range 1, 2 and 3
respectively. In TC and VOC systems, the TOC CALIBRATION
1/2/3 menus are named as TC CALIBRATION 1/2/3.

The first column shows the number of calibration points, the
second point [%] shows the calibration factors automatically
calculated from the calibration data, the third column
STANDARD shows the standard solution concentrations and the
fourth column shows the un-calibrated result (mgC/l) measured
and calculated from the CO
2
analyzer readings.

System calibration curves should not be modified by the user on
site unless a recalibration of the system is required at a different
analysis range.
8.3.4 Sequence Program
8.3.4.1 Average Program
LOG AVERAGE NO 
LOG AVERAGE function enables (YES) or disables (NO by
default) the 24-hour averaging of the reaction results in the
reaction archive.

The reaction results obtained from manual samples are not
included in the averaging calculations.
AVERAGE UPDATE 00:00

If the LOG AVERAGE above is enabled (YES), the system
calculates a 24 hours average of the reaction results and
displays it in the reaction archive for each stream at the time
programmed for AVERAGE UPDATE (00:00, HR:MIN, by
default).
