Serinus® 10 User Manual 3.2
This is the abbreviation for Ozone.
A gas sample of known composition and concentration used to
calibrate/check the upper range of the instrument (Ozone).
Zero calibration uses zero air (Ozone scrubbed ambient air) to
calibrate/check the lower range of the instrument.
Background is the reading of the sample without Ozone present in the
measurement cell.
Multipoint Precision Check
A procedure to verify the linearity of the response of the instrument.
The process of adjusting the instrument to ensure that it is measuring
the correct concentration.
The change in instrument response to zero air over a period of
continuous unadjusted operation.
Is purified air in which the concentration of O3 is < 0.5 ppb with water
vapour of less than 10% RH. Sufficient purified air can be obtained by
passing dry ambient air through an activated charcoal scrubber and a
particulate filter.
Span gas that is delivered via an external Ozone generator.
Sample air is defined as the sample before it has entered the
measurement cell, as distinguished from the exhaust air.
Exhaust air is the sample air after it has passed through the
measurement cell and is moving towards being expelled from the
instrument.
These are measurements of tubing. ID is the internal diameter of
tubing; OD is the outer diameter.
A configuration of multiple instruments connected via the same RS232
cable.
A program that checks whether the current firmware is valid, executes
the instrument start-up. The Bootloader can be entered by pressing
the ‘+’ key on the front keypad during the first ½ second after power
ON and following the prompts. The Bootloader enables various low-
level recovery tools, including updating the main firmware from a USB
stick.
Printed Circuit Assembly. An electronic circuit mounted on a printed
circuit board to perform a specific electronic function.
The analytical process of measuring Ozone.
Standard litres per minute. This is the flow referenced to standard
temperature and pressure conditions. For the purposes of this manual,
all flows are referenced to 0 °C and 101.3 kpa (1 atm).
