Check Wick and Fill Natural Wet Bulb
The QUESTemp 32 uses a cotton wick immersed into a reservoir containing distilled
water. DO NOT use ordinary tap water, as the contaminants that are left behind
after evaporation will shorten the life of the wick and cause high readings. If the wick
is discolored, it should be replaced. To replace the wick, slide the old wick off the
top of the sensor. Place a new wick over the sensor, making sure that the bottom of
the wick is down in the reservoir.
