STEL and TWA mode
(weighted average)
When the STEL or the TWA mode has been se-
lected, the meter will show the weighted average of
the readings during the last 15 minutes or the last 8
hours.
When the meter is turned on for less than 15
minutes (8 hours) the STEL value (TWA value)
will be the weighted average of readings taken
since the meter was switched on.
It takes at least 5 minutes to calculate STEL and
TWA. The display shows "----" during the first 5
minutes after having the meter switched on.
The STEL and TWA values are updated every 5
minutes.
Press START/ESC to return to the normal
measurement mode.
