  • Page 5: Introduction

    Introduction Introduction List of Tables Introduction The QUESTempº 48N offers 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 create a Waterless Wet Bulb calculation through a combination of dry bulb temperature, globe temperature, relative humidity, and air flow.

  • Page 6: Getting Started

    Getting Started Getting Started Up and Running Overview Getting Started Up and Running Overview 1. Place the QUESTemp 48N in the work area in a safe location approximately 3.5 feet º 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.

    Sensors Sensors Globe Thermometer To power off, press and hold the I/O Enter key from the main menu. Sensors Globe Thermometer The globe thermometer (left position) gives an indication of the radiant heat exposure on an individual due to either direct sunlight or hot objects in the environment. This is accomplished by placing a temperature sensor inside a blackened copper sphere and measuring the temperature rise.

  • Page 11: Measurements

    Measurements Measurements WetBulb Globe Temperature (WBGT) Measurements The QUESTemp 48N data logging, with an event logging mode, 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), and the Stay Times Indices for ACGIH, U.S.

    Electronic Electronic Sensor Check Sensor Check Performing an Electronic Sensor Check Electronic Sensor Check A verification module, TSI model 053-923, may be used to check the operation of the QUESTemp monitor’s wet bulb, dry bulb, and globe. The purpose is to verify that the electronic components are within a specific range with known values and a known source.

  • Page 20: Sensor Alignment

    Sensor Sensor Alignment Alignment RH Sensor Alignment Sensor Alignment For highly accurate measurement readings, you should align your QUESTempº 48N prior to data logging or event logging/recording. For the RH sensor, it is recommended to align with a High concentration level using the 75% sensor salt, NaCl (sodium chloride), or a Low concentration level using the, the 33% sensor salt, MgCl (magnesium chloride).
  • Page 21 Sensor Alignment RH Sensor Alignment Place a latex finger cot (user supplied) over the humidity sensor in order for the sensor to stabilize quicker about 15 minutes (or up to 60 minutes without).  NOTE: Latex finger cots can be found at various hardware stores or online such as colepalmer.com.
  • Page 22 Sensor Alignment RH Sensor Alignment In either the High/Low RH alignment screen, adjust the level to the percentage displayed on the salt container by using the Up/Down Arrow keys. Press I/O Enter key to save. (The instrument will state either “Successful” or “Failure” if it passed/did not pass. For “Failure” repeat the steps above.) Example of high RH percentage prior to Press Enter to save the alignment.
