Notes:
The AHLU upper limit in the Cattle Heat Stress Tracker
is 400. Dr. John Gaughan, University of Queensland, provided
guidance on using this value.
To highlight the severity of conditions, if the Red Warning Zone
is reached, the line indicating the current zone will flash. If the
Black Warning Zone is reached, the measurement value will
flash inverted.
If an alert is activated, pressing
on the AHLU/HLI/THI
Measurement Screen will deactivate the alert until the
next higher threshold is reached or until the AHLU/HLI/THI
measurement dips below the threshold and then raises above
it again.
In the Options Menu under
Display
, there is an
Alerts Test
function which will activate the light and buzzer. When using
the unit in a new situation, test the alerts to familiarize yourself
with their intensity.
HOW TO MEASURE WBGT, AHLU, HLI and THI
ACCURATELY:
» Differences in the reflectivity of ground surfaces such
as grass or asphalt will impact measurements. Be
sure to take measurements in the same solar/radiant
heat environment as the people and animals you are
monitoring.
» When changing environments (moving from an air
conditioned room to outdoors or removing the unit
from your pocket) the unit requires between 8-15
minutes to equilibrate to its surroundings before
taking readings.
» Take measurements at least 3 feet off the ground and
in the same wind or air flow conditions as the people
or animals you are monitoring. Ensure the Kestrel
is oriented into the wind and able to measure the
full wind value. A tripod or pole mount and the
Kestrel Rotating Vane Mount are ideal for ensuring
accurate measurements.
