1. Make sure the wet bulb’s wick is clean. Fill the reservoir with distilled water.
2. Place the QUESTemp in the work area in a safe location approximately 3.5 feet
off the ground.
3. Turn the unit ON. If the battery voltage displayed during the power-on sequence
is less than or equal to 6.4 volts, replace or recharge the batteries.
4. Use the arrow keys to set the display to the desired items.
5. Allow 10 minutes for the sensors to stabilize to the environment before taking
readings.
Check Wick and Fill Natural Wet Bulb
The QUESTemp uses a cotton wick immersed into a reservoir containing distilled water.
Ordinary tap water should not be used, 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.
