AINTENANCE
Store the VapoMeter in its case, in a clean and dry place. The storage temperature and
relative humidity should be close to operating conditions. Avoid conditions where
condensation can occur, for example quick temperature changes. Prevent any
solutions, dirt and dust from entering the measurement chamber. Avoid exposing the
VapoMeter to excessive draft and vibration or direct sun light.
Cleaning
Clean the cover with a mild detergent solution. The adapters are removable and can be
cleaned separately. Clean the adapters with an antiseptic cleansing towel or ethanol
and let them dry properly after cleaning. Do not spray any cleaning solution or any
liquid on the humidity sensor.
Batteries
One set of alkaline batteries lasts typically up to 3000 measurements. If the device is
not used for several months it is recommended to remove the batteries.
The batteries are tested automatically and a warning about low batteries appears on
the display when the voltage goes under 2.3 V. Change the batteries when the
remaining charge in the battery indicator [3] turns red. If the message REPLACE
BATTERIES appears when the VapoMeter is switched on, measurements cannot be
done before the batteries are changed.
When changing batteries:
1. Unscrew the bottom half and remove it carefully, without pulling the wires.
2. Remove the empty batteries carefully.
