Note: Make sure the tail end of the wet-bulb wick is aligned with the tip of the wet-bulb
temperature sensor. Humidity control can be destabilized if the sensor is overly
exposed or it the sensor is out of position.
3. Curve the ends of the wet-bulb wick so it sits smoothly on the bottom of the wick pan.
4. Lay the ends of the wet-bulb wick in the central trough of the wick pan.
FIGURE 6.37. HOW TO SET THE WET BULB WICK
Note: When running a temperature-humidity program, always supply the wick with water,
even during temperature-only parts of the program. Unless water is continually
supplied, the wick may dry out which will interrupt testing.
Remove the wet-bulb wick for temperature-only tests, especially if running the chamber
above ambient temperature. Should the wick dry out, it will be harder to supply it with
water, which will throw off humidity measurements the next time a humidity test is run.
