WBGT indoor index, WBGT outdoor index, relative humidity, and Heat Index or Humidex. These models support RS- 232 communications and works with the optional software analysis program, 3M Detection Management Software (DMS). With the QUESTempº 36, you have the capability to display stay times in order to manage work/rest regimens. -
Page 6: Getting Started
Getting started Getting Started Up and Running overview Getting Started Up and Running overview 1. Make sure the wet bulb wick is clean. Fill reservoir with distilled water. • See “check wick and fill natural wet bulb”, pg 5. Place the QUESTempº 34 & 36 in the work area in a safe location approximately 3.5 feet off the ground. -
Page 7: Keypad Operation
Getting Started Keypad Operation Keypad Operation The unit operates using a keypad with 4 keys. The I/O Enter key responds when the key is released while all other keys respond when the key is pressed. I/O Enter key The unit turns on with a single key press. The unit turns off by holding the key down while a countdown of 3-2-1 occurs in the lower right corner of the display. -

Sensors Sensors Natural Wet Bulb Thermometer A. Globe thermometer Sensors B. Natural wet bulb thermometer C. Dry bulb thermometer Natural Wet Bulb Thermometer The natural wet bulb thermometer gives an indication of the effects of humidity on an individual. Relative humidity and wind speed are taken into account by measuring the amount of evaporative cooling taking place at a thermometer covered with a moistened wick. -

Page 12: Heat Index/Humidex
Tri-sensor Calculation and Remote Cable Heat Index/Humidex Heat Index/Humidex The Heat Index is determined using the dry bulb temperature and relative humidity. Based upon charts available from the U.S. National Weather Service, Heat Index represents how an average person feels relative to climate conditions. For a given temperature, the higher the humidity, the higher the heat index. -

Page 20: Air Flow Functionality
Air Flow functionality Air Flow functionality (Available using 3M’s Air Probe on QUESTempº 36 model.) Air flow is measured in meters per second over a range of 0 to 20m/s in 0.1m/s increments. The sensor should be placed or held perpendicular in the air stream. -
Page 21: Operating Sequence
Continuous charging is not a safety concern. Operational Check A verification module, 3M model 053-923, may be used to check the operation of the QUESTemp. Remove the top sensor bar and plug the verification module into the top of the unit. -
Page 22: Power Options
Power options 9-Volt Alkaline Battery Replacement Power options There are 3 options for powering the QUESTempº 36: a 9-volt alkaline battery, a NiMH (Nickel Metal Hydride) rechargeable 6-cell battery pack, and an AC adapter. A door on the back of the unit allows the user access to the 9-volt battery. The rechargeable battery pack is located inside of the unit. -
Page 23: Nimh Battery Pack
WARNING: Recharge batteries only in a non-hazardous environment. The NiMH rechargeable battery pack is charged in the instrument using 3M’s AC 120V AC to 9V DC adapter (part #015-910) or 220V AC to 9V DC adapter (part #015-680). A discharged battery pack requires an “overnight” charge of 16 hours (for the 120V adapter). -
