4.4 Temperature control
On the inside of the battery compartment lid are
two thermo-sensitive stickers. They react at a
exceeded temperature of 60°C (140°F) respec-
tively 65°C (149°F). When these temperatures are
exceeded, the color of the stickers turn to black.
If the temperature has exceeded 65°C (149°F)
please return the instrument to the manufacturer
for verification.
4.5 Heatsinks
It is very important that the heatsinks are shaken
from time to time while they are cooling down. This
serves a better mixture of the different compo-
nents.
Maximum duration time:
at 100°C (212°F) up to 8.5 hours
at 200°C (392°F) up to 2.5 hours
at 250°C (482°F) up to 2.0 hours
4.6 Special Notes on the Thermal Barrier
All parts can be hot after the measurement.
Remove the hot thermal barrier from the belt
wearing appropriate protective clothing (protective
gloves). Open the thermal barrier and press the
start/stop key of the data logger.
Cooling Down the Protective Parts:
Place hot thermal barriers on heat-resistant
spacers, a ceramic fiber blanket or refractory
material to ensure uniform cooling. Placing a hot
thermal barrier directly onto a cold surface may
