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.-6. TOC/TN Zero Adjust. The TOC/TN Zero Adjust is used to compensate any organic carbon and nitrogen
contamination in the Acid and Base reagents and any absorbed CO
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.
The TOC Zero Adjust values are the Zero Offset values in mgC/l measured by the CO
Zero Adjust values are the Zero Offset Absorbance values measured by the Photometer.
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) for each parameter 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).
