Parameter Description
Background Gas
Displays the background gas that the unit was calibrated in
% O2
(if HSR=OFF)
Real oxygen reading in %
Display resolution = 0.01
(Display resolution 0.1% when min value is >=20%)
% O2p
(if HSR = ON)
HSR oxygen reading (extrapolated quick response value of real
oxygen reading)
Real oxygen value is displayed in status bar
Flashing “Heating”
Symbol
This flashes until cell temperature is stable at set point ±0.5°C for
minimum of 5 minutes
Status Bar Flashes any system warnings and error messages (see below)
