1Introduction

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.

QUESTempº Models

The QUESTempº 34 and QUESTempº 36 models measure and calculate the dry bulb

temperature, wet bulb temperature, globe temperature, 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, TSI Detection

Management Software (DMS).

With the QUESTempº 36, you have the capability to display stay times in order to manage

work/rest regimens. Guidance is based on the screening criteria for heat stress as defined in the

ACGIH TLV Handbook, U.S. Navy PHEL charts, and EPRI Action Limits. (See Appendix B for

detailed chart information.)

An additional feature with the QUESTempº 36 is an optional detachable air-probe for measuring

air velocity (wind speed) to determine appropriate levels of indoor thermal comfort monitoring.

Introduction

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. DO NOT use

ordinary tap water.

• See “check wick and fill natural wet bulb”.

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 6.4 volts, replace or recharge the batteries.

4. Be aware that the sensors require 10 minutes to stabilize to a new environment.

5. In the main menu, View will be selected (an indicator arrow denotes the selected menu).

Press the I/O Enter key to select.

6. Press the Run/Stop key to begin storing data.

7. Use the Up/Down Arrow keys to set the display to the desired items.

Getting started

Getting Started

Keypad Operation

The unit operates using a keypad with four keys. The I/O Enter key responds when the key is

released while all other keys respond when the key is pressed.

Keys

Explanation

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.

Pressing and releasing the key while viewing temperatures causes

the display to view the next available sensor bar (indicated in the

upper right corner of the display).

Up Arrow key

Changes items appearing in the display. Scrolls up.

Down Arrow key

Changes items appearing in the display. Scrolls down.

Run/Stop key

From the menu or view modes, pressing this key starts or stops the

run mode. Pressing this key will exit the setup, print or reset

modes.

Escaping or moving

back one screen

If you are in the setup, print, reset, or calibration screens, you can

press Run/Stop key to escape or move back one screen.

NOTE: The QUESTempº 34 & 36 models have the same keypad. Figure 1-2 is an example

of the QUESTempº 36 model with the optional air-probe attachment.

Getting Started

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 PRINT

SETUP RESET

Indicator arrow

Indicates the selected menu option. Then press I/O

enter to select or press up/down arrows to select

another option

Figure 1-3: Main menu of the QUESTempº 34 & 36

2. Press the I/O Enter key (when view is selected) to access the measurement screens.

The Wet and Dry measurements screen will display. (See Figure 1-6 for screen

example.)

3. To view different measurements, press the Up or Down arrow key to toggle through the

views.

NOTE: There are five user-selectable languages. If you see the fields such as Wet, Dry,

WBGTi, and WBGTo this indicates the measurements are displaying in English.

To display an alternative language, select Setup from the main menu. Press the Down

arrow repeatedly until “English” (or the appropriate language) appears. Then repeatedly

press the I/O enter key to toggle through the languages. Once selected, all menus and

measurement screens will change to the selected language. To return to the main

menu, press the Run/Stop key.

4. To return to the main menu, press and hold the I/O Enter key (3, 2, 1 countdown will

appear) and the main menu will display.

To select an option on the main menu, press the up or down arrow until an arrow

appears directly in front of the appropriate menu selection and then press I/O enter key.

5. To power off, press and hold the I/O enter key from the main menu.

Placement for Monitoring/Testing

The QUESTempº 34 & 36 model should be placed at a height of 3.5 feet (1.1 m) for standing

individuals or 2 feet (.6 m) for seated individuals. Tripod mounting is recommended to get the unit

away from anything that might block radiant heat or air flow. A 1/4" x 20 threaded bushing on the

bottom of the instrument allows mounting to a standard photographic tripod. DO NOT stand close to

the unit during sampling.

NOTE: Before measuring, allow 10 minutes for the sensors readings to stabilize.

Sensors

Natural Wet 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.

Check Wick and Fill Natural Wet Bulb

The QUESTemp° Heat Stress Monitor uses a cotton wick immersed into a reservoir containing

distilled water. DO NOT use ordinary tap water, as the contaminants that are left behind after

evaporation will shorten the life of the wick and cause high readings. If the wick is discolored it

should be replaced. To replace the wick, slide the old wick off the top of the sensor. Place a

new wick over the sensor, making sure that the bottom of the wick is down in the reservoir.

Reservoir

Filling wet bulb reservoir

1. Remove reservoir cover and fill with

distilled or de-ionized water.

2. Replace reservoir cover.

Figure 1-4: Filling wet bulb reservoir

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. The WBGT index is based on the response of a 6 inch diameter globe. The QUESTemp°

uses a 2-inch diameter globe for a faster response time. The temperature of the 2-inch globe is

correlated to match that of a 6 inch globe.

Sensors

Dry Bulb Thermometer

The dry bulb thermometer (right position) measures the ambient air temperature. This

measurement is used in the outdoor WBGT calculation when a high solar radiant heat load may

be present. The series of white plates surrounding the sensor shield it from radiant heat.

Relative Humidity Sensor

A relative humidity sensor is located in a compartment inside of the sensor bar housing. Slots in

the housing allow air to circulate around the sensor.
