Press the I/O Enter key to turn on. Proceeding the model and revision information displayed on the screen, the main menu will appear. VIEW SETUP PRINT RESET Indicator arrow Indicates the selected menu option.
Sensors 5 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. (This is indicated in the diagram below.
6 Remote, Sensors 2 and 3 Tri-sensor weighted average Remote Sensors 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 60°C. The sensor 2 and sensor 3 jacks on the side of the instrument allow simultaneous monitoring of up to three sensor arrays using connecting cables.
Measurements 7 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. Using inputs on the side of the instrument, two additional sensor arrays can monitor up to three locations simultaneously.
8 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.
9 Measurements Thermal Comfort Thermal Comfort Thermal comfort readings for indoor environments are a benefit of Detection Management Software (DMS) 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.

Electronic Sensor check Electronic sensor check 16 Performing an electronic sensor check Electronic sensor check A verification module, Quest model 053-923, may be used to check the operation of the QUESTemp’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. The temperature tolerances should be within +/-0.5oC.
Sensor alignment Sensor Alignment 17 RH Sensor Alignment Sensor Alignment For highly accurate measurement readings, you should align your QUESTempº 44/46 prior to data logging. 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). (See ColePalmer.com to order sensor alignment salts.
Sensor Alignment 18 RH Sensor Alignment 6. Place the Salt container, with the salt alignment cap removed, over the RH sensor (middle sensor). Allow level to stabilize for at least 15 minutes. (Refer to Figure 123.) • About sensor alignment: if readings are within +/- 0.5%, a change in sensor alignment is not required. Skip to step 7 to return to main menu. NOTE: For a High alignment, use the 75% sensor alignment salt (NaCL) and for a Low alignment, use the 33% alignment salt (MgCl).
Printing 19 PrintingPrinting Serial Printing The recorded data can be sent to a computer through the serial RS232 port or to a parallel printer. Serial transmission requires Quest cable #54-715. Parallel transmission requires Quest cable #56-875. With the cable plugged in, select PRINT from the menu and press the I/O Enter key to enter the PRINT mode. Begin printing by pressing the I/O Enter key. Press the key again to abort printing.
