Automatic-off-function:
Device will be automatically switched off if no key is pressed/no interface communica-
tion takes place for the time of the power-off delay. The power-off delay can be set to
values between 1and 120 min.; it can be completely deactivated.
Min-/max-value memory:
Both the max. and the min. value will be memorized for each measurement taken.
Hold-function:
Press button to memorize current measuring values.
Alarm function:
monitoring of alarm limits (% oxygen), measuring range limits (% oxygen and tempera-
ture) and device faults.
alarm via display element and interface, additional audio alarm optional
