To ensure that the correct zero offset is applied and to eliminate any remaining TOC
contamination from the analyzer, a Service Zero cycle should be initiated using the SET SERVICE
ZERO function in the Service menu. When initiated, BioTector automatically runs a total of 10 zero
calibration cycles during the following 500 online measurements and automatically adjusts the
zero offset values to compensate for the removal of the contamination. It will therefore not be
necessary to revisit the BioTector after the startup or to repeat the Zero Calibration cycle
manually. See Section
8.1.7 Service for further details. (If ultra-pure water is used during the
Zero Calibration, ensure that container with at least 5 liters of water is connected to the analyzer. It
is recommended to use a sealed container with CO
2
absorber and HEPA air filter installed in line
on the vent/breathing tube to prevent the contamination of the water.)
