A STEL alarm cannot be cleared except by turning the unit off and back on,
but will clear automatically after 15 minutes in clean air.

TWA
This displays the Time-Weighted Average (TWA) calculation, which is the
average concentration times the fraction of 8 hours that the instrument has
been on. The TWA value is similar to a dose in that it rises but never falls,
until it is reset by turning the unit off. Likewise, a TWA alarm cannot be
cleared except by turning the unit off and back on.

turned on.

the Left Key again to acknowledge and clear the Peak
value.

Minimum (Oxygen Sensor Only)
The Minimum screen is used for the oxygen sensor only
and shows the lowest value since the unit was turned on.

to enter the Clear Min screen and Press
the Left Key again to acknowledge and clear the Min value.

Alarm Log
Up to 50 alarm events lasting ≥5 seconds are logged into
memory and the last 10 such events can be viewed on the
instrument. When A 1 is reached using the Right Key, it
flashes between the A 1 screen and a screen showing the
alarm concentration and type. Use the Left Key to cycle
through the 10 available alarms. To view all 50 alarm
events along with date and time stamps, it is necessary to
use a Docking Box or CaliCase connected to a computer
with mPower Suite software.
