Page 7: Introduction
Introduction Introduction Up and Running overview Introduction The new heat stress instruments, the QUESTempº 44 and QUESTempº 46, offer traditional heat stress monitoring without the aggravation of maintaining a wet bulb. Through collaboration with Professor Dr. Thomas Bernard, from the College of Public Health at the University of South Florida, mathematical models were implemented to Waterless Wet Bulb calculation create a... -
Page 8: Getting Started
Getting Started Getting Started Up and Running overview Getting Started Up and Running overview 1. Place the QUESTempº 44/46 in the work area in a safe location approximately 3.5 feet off the ground. 2. 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. -
Page 9: I/O Enter Key
Getting Started Keypad Operation 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. This key is also used to select a mode (such as Setup or View) or enter setup changes. -
Page 10: Turning On/Off And Basic Operation
Getting Started Turning on/off and basic operation Turning on/off and basic operation To quickly get you started with the QUESTempº 44/46, the following section explains how to turn on the instrument, run, and stop your session. Press the I/O Enter key to turn on. Proceeding the model and revision information displayed on the screen, the main menu will appear. -
Page 11: Sensors
Sensors Sensors About the sensor bar Sensors About the sensor bar The sensor bar, on the QTº 44/46, is calibrated to its specific instrument and is not interchangeable with other QTº 44/46. The instrument has a sensor bar label which includes the serial number of the instrument and a sensor bar number. -
Page 12: Remote, Sensors 2 And 3
Remote Sensors Remote, Sensors 2 and 3 Tri-sensor weighted average Remote, Sensors 2 and 3 The top sensor bar (sensor 1) may be removed from the instrument and used through a remote cable. Shelter the instrument and remote the sensor bar if the measured environment is expecting heavy rain or if temperatures are above 60C. -
Page 13: Measurements
Measurements Measurements Waterless Wetbulb Measurements The QUESTemp 44/46 data logging area heat stress monitor directly senses three parameters: dry bulb temperature (DB), globe temperature (G), and relative humidity (RH). It computes the wet bulb (WB), the Wet Bulb Globe Temperature (WBGT), stay times for four possible indices, and the Heat Index (HI) or the Canadian Humidex. -
Page 14: Wetbulb Globe Temperature
Measurements WetBulb Globe Temperature WetBulb Globe Temperature The WBGT is a weighted average of the three temperature sensors using the following formulas: WBGT (indoor) = 0.7WB + 0.3G (denoted as “WBGTi” on the display) WBGT (outdoor) = 0.7WB + 0.2G + 0.1DB (denoted as “WBGTo” on the display) The resulting WBGT values can then be compared to indices of work-rest regimens (stay times) based upon work loads. -
Page 15: Thermal Comfort
Measurements Thermal Comfort Thermal Comfort Thermal comfort readings for indoor environments are a benefit of QuestSuite software and are not displayed or printed from the instrument directly. Readings are derived from the dry bulb, relative humidity, mean radiant temperature, airflow, and user entered parameters of clothing, metabolic rate and external work. Thermal comfort indices, Predicted Mean Vote (PMV) and Predicted Percent Dissatisfied (PPD), help predict the thermal satisfaction level of a person with their indoor environment. -

Airflow Functionality Airflow functionality Airflow functionality (Available using Quest’s Air Probe on QUESTempº 46 model only) Airflow 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. Unlike many anemometers, the omni-directional sensor does not require rotating to find the maximum reading. -
