Operating and maintenance recommendations
Recommendations for metrological control _______________
Metrological verification is performed according to the requirements of your
own application in user-defined terms. In some cases, the calibration must
be performed by an independent state-accredited laboratory.
Recommendations for regular checks ___________________
The manufacturer recommends that the system in which the device is
incorporated be checked at regular intervals. The range and scope of the
tour depends on the application and the user's internal regulations. It is
recommended to perform these checks:

metrological verification

regular checks at intervals as specified by the user

evaluation of all the problems that have occurred since the last
inspection

visual inspection of the device, check the condition of connectors and
cables, and cover integrity
How to replace the battery ____________________________
The battery may only be replaced by a person who knows the principles of
safe handling of lithium primary batteries. Do not throw them into a fire, do
not expose them to high temperatures, and do not mechanically damage
them. Dispose the used batteries to hazardous waste.
If the low battery symbol
starts to appear in the COMET cloud
received messages during operation, it is advisable to replace the
transmitter battery in the next 2-3 weeks. The empty battery symbol also
appears on the device display. A low battery indication may also occur if
the device is operated at extremely low temperatures even when the
battery is still usable (usually outdoors when in out-of-night messages).
During the day (after temperature rise), the indication disappears. In this
case, it is not necessary to change the battery.
A critically weak battery that can fail at any time is indicated by a blank
battery symbol
in the COMET cloud and flashing the empty battery
symbol on the device display. Replace the battery as soon as possible.
Note: When operating the transmitter at very low temperatures, the flashing
of the blank battery symbol may not be on the sensor display visible.
