SENSITIVITY
HOURS:
1
✽
The sensitivity level is by default set to 1. It
means that the system requires only one
hour of significant, high activity before it sets
an alarm. For sensivity level 2, the system
requires two consecutive hours of high
activity. Sensitivity 3 requires 3 consecutive
hours etc. The level can be set between 1
and 10.
Changing the level upwards means that the
system will sift out cows with just a short
period of high activity and less cows will
occur on the activity list.
The sensitivity parameter is set on system
basis in display 6:1:6:4:1. The setting can
be overruled by setting other levels for a
group of cows in display 6:1:6:4:5, GROUP
DATA. See section "No undesired alarms
from a group of cows" further on in this
chapter.

FILTER SETTINGS
The filter has three levels: 50, 60 or 70.
Every level has a corresponding accuracy
expressed in %.
Default values are shown in the display, 50
corresponds to one plus sign, 60 to two plus
signs and 70 to three plus signs.
Each level can be adjusted upwards and
downwards by changing the activity level
value.
Adjustments of activity levels can be very
effective in optmizing heat detection on
individual farms. The higher the accuracy,
the lower the numbers of cows identified,
both positive and false positive. With a high
accuracy you will be more accurate in
identifying high activity cows, but you may
also miss cows showing heat signs.
