Stability Limit
The stability limit setting is used to determine when the secondary
display will indicate that the reading is stable. There are 4 preset
settings for stability (0.01, 0.1, 1.0, or 10.0) expressed in the presently
selected units.

Change the unit stability limit setting to the next greater
setting.
 Change the unit stability limit setting to the next lesser

Stabilty Display
The stability display shows the general stability level relative to a user
configurable stability limit. There are 4 preset settings for stability
represented in °C or °F (0.01, 0.1, 1.0, or 10.0). When the limit is
exceeded, it also shows the general direction in which the readings are
presently moving. The stability level is calculated from a moving
sample window of six seconds duration, with the value extrapolated to
a 1 minute time base.
Segments are turned on to indicate the stability level as follows:
• Center only (stable) when half of the 1 minute trend value is less than
or equal to the stability limit, i.e. maximum deviation –limit to +limit.
• Center plus one arrow up or down (depending on the trend) when
half of the 1 minute trend value is greater than the stability limit and
is less than or equal to twice the stability limit.
• Center plus two arrows up or down (depending on the trend) when
half of the 1 minute trend value is greater than twice the stability limit
and is less than or equal to three times the stability limit.
• Center plus three arrows up or down (depending on the trend) when
half of the 1 minute trend value is greater than three times the
stability limit.
