High Alarm Stage 1 temperature (-50°C to +50°C)
The Stage 1 alarm is a time/temperature-related alarm. If the maximum
threshold is exceeded, a timer is initiated, and no further action is taken at
this time.

High Alarm Stage 1 Delay (1 - 99 min.)
After the maximum threshold has been exceeded (Ref. 4 above), the alarm
will not be triggered until the timer exceeds the time delay set here.
If the temperature drops below the threshold before the expiry of this delay,
the timer is reset. If following this the temperature rises above the threshold
again, the timer restarts from zero.

High Alarm Limit Stage 2 temperature (-50°C to +50°C)
If at any time this limit is exceeded the time delays will be overridden and the
alarm will trigger immediately.
