2.3 Calibration Menu
Calibration menu allows the user to calibrate the analyzer. Zero and Span Calibration menus allow the user to
run the zero and span calibration cycles for a single range or for all system ranges available.

Zero Calibration menu allows the user to enter the suggested Zero Adjust values, to start the Reagent Purge
cycle, to start the Zero Calibration and Zero Check cycles and to program the number of zero reactions run at
each range.
1.-3. Zero Adjust. The Zero Adjust is used to compensate any organic contamination in the acid and base
reagents and any absorbed CO
2
in the base reagent. The Zero Adjust values are generated automatically
by the system for each range when the zero calibration cycle is completed without any system warnings.
Zero Calibration cycle is activated by selecting the RUN ZERO CALIBRATION function in this menu.
When a Zero Check cycle is run using the RUN ZERO CHECK function, the system only checks the zero
response at each range and displays the suggested Zero Adjust values in brackets “[ ]” for all ranges next
to the current Zero Adjust settings. When a Zero Check cycle is completed, if necessary the suggested
Zero Adjust values can be programmed manually by entering the corresponding suggested Zero Offset
values for each range (1, 2 and 3) in this menu. When the Zero Adjust settings are entered manually,
system logs this information in the reaction archive with the prefix “ZM” (Zero Manual).
4. Run Reagents Purge. The RUN REAGENTS PURGE function is used to prime all reagents in the
BioTector. If necessary, the pump operation time for Reagent Purge cycle can be increased in the
Reagents Purge menu.
5. Run Zero Calibration. Each time BioTector reagents are replaced or topped up and each time a service
is carried out, it is strongly recommended to use the RUN ZERO CALIBRATION function so that the
system can set the zero offset values automatically. The zero calibration reactions operate in the same
manner as a normal reaction. Depending on system settings, BioTector either takes DI Water as a
sample or does not take any sample during the Zero Calibration cycle. See ZERO WATER in section
8.3.4.2 Zero Program for details. To start the zero calibration, press the ENTER key at this menu
item. An “*” will indicate that the function is running. At the end of the Zero Calibration cycle, the following
settings are checked and updated:
ENTER PASSWORD CALIBRATION ZERO CALIBRATION
