Water supply method
Caution
・
When handling the string of wick, use a pair of tweezers or wash your hands with soap to
prevent the transfer of dirt (such as grease, salt or acid).
・
If the wick or the sensor section becomes dirty, accurate measurements cannot be made.
Use distilled water for the water supply whenever possible.
・
Do not wet the inner wall of the air intake tube. Otherwise, the wet bulb temperature will
become unstable, which may result in measurement errors.
1.
Carefully pull the string from the guide above the water
reservoir and put the string into water reservoir.
2. Fill the water reservoir to four-fifths with distilled water,
using the water bottle supplied (Approx. 13 cc).
Pour water to the string so that the temperature bulb
also gets wet.
As for the replacing the wet bulb wick, refer to the
“Maintenance” on the page 22.
