Description
Displays the background gas that the unit was calibrated in
Real oxygen reading in %
Display resolution = 0.01
(Display resolution 0.1% when min value is >=20%)

oxygen reading)
Real oxygen value is displayed in status bar
This flashes until cell temperature is stable at set point ±0.5°C for
minimum of 5 minutes
