1 Introduction Introduction Up and Running overview Introduction The QUESTempº 34/36 models are portable heat stress monitors that are designed to be rugged, easy-to use instruments to quickly and accurately assess the potential for individual heat stress based on environmental conditions.
Getting started 2 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. 2. Place the QUESTempº 34 & 36 in the work area in a safe location approximately 3.5 feet off the ground. 3. Power On the QUESTempº34 & 36 and check the battery. • If the battery voltage displayed during the power-on sequence is less than or equal to 6.
3 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. This key is also used to select a mode (such as Setup or View) or enter setup changes.
4 Placement for Monitoring/Testing Turning On/Off and Basic Operation Turning On/Off and Basic Operation To quickly get you started with the QUESTempº 34 & 36 model, the following section explains how to turn on the instrument, run, and stop your session. 1. Press the I/O Enter key to turn on. Following 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 Natural Wet Bulb Thermometer A B C A. Globe thermometer B. Natural wet bulb thermometer C. Dry bulb thermometer Sensors 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.
Remote 6 Tri-sensor Calculation and Remote Cable Tri-sensor Weighted Average Tri-sensor Calculation and Remote Cable 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 Tri-sensor Calculation and Remote Cable Wet Bulb Globe Temperature Measurements The QUESTemp° 34 & 36 data logging area heat stress monitor directly senses the four parameters: ambient or dry bulb temperature (DB), natural wet bulb temperature (WB), globe temperature (G), and relative humidity (RH). The QT° 34/ 36 compute the Wet Bulb Globe Temperature (WBGT), stay times for three possible indices (QT° 36 only), and the Heat Index (HI) or the Canadian Humidex.
8 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.
Operating 9 Operating QUESTempº 34 & 36 View Operating QUESTempº 34 & 36 Use the Up Arrow and Down Arrow keys to move the marker in the display in front of the desired mode. Pressing the I/O Enter key will select the mode. View Displays the measured data but does not log it. If more than one set of sensors is plugged into the unit, these can be displayed by pressing and releasing the I/O ENTER key. The displayed sensor set is shown in the upper right corner. WET 65.5º F DRY 74.
10 Operating QUESTempº 34 & 36 Print • • 3. Flow: On, Off . Index: none, ACGIH, Navy, EPRI and select either: WBGTi (indoor), WBGTo (outdoor) for Index setting. Index Settings Explanation TLV and action limit These index settings only apply to the ACGIH Index. EPRI and Navy will ignore this setting. Clothing Correction Parameters are set from 0 - 9.9°C. This is a clothing correction for the WBGT in degrees Celsius and is applied to the selected WBGT when the work duration is calculated.
11 Displayed items Displayed Items Run Run The run mode begins a session in memory and logs the data. 1. Begin a session by pressing the Run/Stop key from the view mode (or measurement view). An asterisk in the lower right corner indicates the run mode. To toggle through the views, press the up or down arrow. WBGTi 66.7º F 1 WBGTo 68.6º F Run indicator Figure 1-8: Run mode indicator 2.

13 Data Logging Stay Time Stay Time The screen(s) displaying stay time data appear different for each of the possible indices (available with QUESTempº 36 model only). If ACGIH is selected, the recommended working minutes per hour are shown for each of the workload categories Light (L), Moderate (M), Heavy (H), and Very Heavy (VH). (Please see Figure 1-14 above.) If the Navy PHELS are selected, the recommended working hours are shown based on a maximum of eight hours.
Printing 14 Printing Serial Printing The recorded data can be sent to a computer through the serial RS-232 port or to a parallel printer. Serial transmission requires 3M cable #54-715. Parallel transmission requires 3M cable #56-875. With the cable plugged into the RS-232 auxiliary port, 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.

16 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. Unlike many anemometers, the omni-directional sensor does not require rotating to find the maximum reading. Be careful not to block the air flow with your body during measurements.
17 Operational Check Operating sequence Operational check Operating sequence 1. 2. 3. Turn Flow On in the setup menu of the QUESTemp° 36. Plug the Air Probe into the port labeled Flow on the side of the QUESTemp° 36. Turn on the Air Probe ON and make sure the green lamp is lit. • In the View or Run modes, air flow is displayed on the fifth screen. Data Logging Air Flow To data log air flow in the QUESTemp° 36, the following two conditions must be met. 1. First, turn Flow On in the setup menu. 2.
18 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. If the rechargeable battery pack ever needs to be replaced, it can be accessed by removing the screws from the bottom panel of the unit.
19 Power options NiMH Battery Pack 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).
