I. INTRODUCTION

The QUESTEMPNII is an easy to use personal heat stress indicator which
monitors the human body's temperature via the ear canal. Any offset
between the ear and body temperatures is adjusted for by calibrating
directly to the individual's oral temperature.

The QUESTEMPNII personal monitor is intended to be a part of a well managed
heat stress program. It is an alerting device which warns the user that
their body temperature has risen above the "safe" level and that action
should soon be taken to allow the body to cool. The QUESTEMPNII monitor
acts as an aid and does not replace the individuals own feelings and
judgement.

The hypothalamus, located at the base of the brain, is the body's
temperature controller. The ear canal borders the hypothalamus and will
track its temperature changes once the canal is isolated from the outside
environment. A small sensor is placed in the ear canal, via an E.A.R.®
earplug, which will monitor the change in the body's temperature and set
off an audible alarm when the level reaches a preset limit. The
recommended limit is 38°C according to the WORLD HEALTH ORGANIZATION and
has been accepted by the ACGIH, NIOSH, and the International Organization
for Standardization. These organizations also recognize that closely
monitored, acclimatized individuals may have a higher tolerance limit of up
to 39°C. As the temperature rises above the limit, the risk of heat
related problems occurring increases. The QUESTEMP°II has the capability
of setting the initial alarm level between 38°C and 39°C and it will
automatically produce a secondary alarm if the temperature exceeds 0.5°C
above the initial alarm level.

Many people who work in hot and humid areas, particularly those enclosed in
protective suits, are in danger of overheating and becoming heat stressed.
Heat stress can occur when the body's cooling system can not keep up with
the heat induced by the activity or environment of the worker. Some
symptoms of overheating are dizziness, exhaustion, heat cramps,
dehydration, heat collapse, or, in extreme cases, heat stroke or death.
Workers in steel mills, asbestos cleaning, power plants and heavy machine
operators are examples of people who may often find themselves in
environments posing a risk for heat related illnesses.

The QUESTEMPNII consists of a belt or pocket worn electronic assembly with
a thin flexible cable leading up to a small earmold which contains the
sensor and a small speaker for an audible alert. The sensing device
protrudes from the earmold and a disposable E.A.R.® foam earplug slides
over the sensor providing a comfortable vehicle for inserting and
maintaining the sensor. The speaker and earmold remain just outside of the
ear to completely avoid any possible damage or injury to the ear canal.

II. FUNCTIONS

AMBIENT COMPENSATION
Unique to the QUESTEMP°II, a second sensor, located in the earmold, will
sense and compensate for any non-drastic changes (less than +/-10°C) in the
thermal environment. This is necessary because changes in the thermal
environment will have an effect on the outer tissues of the body including
the ear canal. By compensating for these changes, error induced by the
environment is notably reduced.

The earmold temperature is data logged and included in the printout as an
indicator of the changing thermal environment.

If the thermal environment changes drastically (greater than +/- 10°C),
then the QUESTEMP°II should be recalibrated in that environment.

KEYPAD FUNCTIONS
A desired function is activated by simply depressing and releasing the
corresponding key. For the functions CAL, PRINT, CLOCK, PRINT RATE, and
ALARM LEVEL, when the key is pressed once the current value or setting will
appear in the display. Pressing the same key a second time (consecutively)
will allow that setting to be changed.

If an oral thermometer is plugged into to the CAL jack,
then the oral temperature will be displayed and updated.
If the thermometer is not plugged in or if the temperature
is below 29.5°C then "o---" will be displayed.

Pressing CAL a second time will display the value of 'ORAL
minus EAR' if the thermometer is in place. Otherwise, it
will display a temperature, which can be adjusted by
pressing the ARROW key, to represent an oral (or core)
temperature. In either case, pressing ENTER will store the
calibration data.

See the section on CALIBRATION for more details.
The default baud rate will appear in the display. If the

ENTER key is pressed then serial ASCII RS232-formatted data
will be sent from the output jack and 'prn' will appear in
the display. If the PRINT/DATA key is pressed a second
time, the displayed baud rate will blink indicating that a
new rate may be selected with the ARROW and ENTER keys.
The baud rate options are 300, 600, 1200, 2400, 4800, and
9600 baud. After pressing ENTER the data will be sent out
and 'prn' will appear in the display.

To halt printing, simply press the PRINT/DATA key again.
The ear temperature will be displayed and the unit will

begin to log the ear (aural) temperature at 10 second
intervals along with temperature of the second sensor
located within the blue earmold. If there is a thermometer
plugged into the CAL jack and its temperature is in the
range between 30°C and 42°C, then its value will also be

logged. All data will be time averaged from 2 second
samples. While the instrument is in the RUN mode, a small
arrow will be displayed in the upper left corner of the
display. Turn the unit OFF to exit the RUN mode.

In the RUN mode, the audible alarm will be activated if the
EAR temperature exceeds the alarm level.

Turning the unit OFF or printing will abort the RUN mode.
If any of CLOCK, PRINT RATE, PRINT, or CAL keys are pressed

while in the RUN mode, the display will show that function's
setting but the unit will continue to data log and check the
temperature. To return the aural temperature to the
display, press the RUN key again.

Shows the current time. Pressing CLOCK a second time will
cause the right-most digit of the time to flash and allows
the clock time to be changed. Cycle through each digit
using the ARROW and ENTER keys (in the same fashion as most
digital watches) to change the time.

Time is displayed in 24 hour format and is maintained in the
unit even when it is turned off. In addition, a lithium
battery backup will maintain the time even when the 9 volt
battery is removed.

Displays the rate at which sampled temperature data will be
printed. Pressing PRINT RATE a second time will cause the
number in the display to flash and a new rate can be
selected using the ARROW and ENTER keys. Selectable rates
are: 10sec, 30sec, 1min, 5min, and 10min. Note that this
only affects the quantity of data printed, not the amount
of data actually stored in the unit.

Displays the current alarm level setting. If ALARM LEVEL
and ARROW are pressed simultaneously, the displayed level
will flash and can be altered between 38°C and 39°C using
the ARROW and ENTER keys. The alarm level may be changed
only if the memory is clear, prior to logging data. Once
run time has accumulated, the unit must be reset to change
the alarm level setting.

In the RUN mode, the audible alarm will be activated if the
EAR temperature exceeds the set alarm level. In addition, a
secondary alarm will sound if the temperature exceeds 0.5°C
above the initial chosen alarm level.

Toggles between Celsius and Fahrenheit while in the RUN
mode. Calibration and alarm levels operate in Celsius
only.

Shows the battery voltage strength in the display while
sounding the audible alarm. The actual battery voltage is
displayed until the level falls below 7.5 volts. Below

7.5V "Lo" appears in the display indicating that the battery should be
replaced with a new 9V alkaline.

The unit will operate for at least 8 hours from the time
that "Lo" first appears. Once the battery voltage falls
below 7.2 volts the alarm will sound continuously and data
logging will cease. If this occurs, turn the unit OFF and
replace the battery with a new 9V alkaline.

ARROW key used to change a parameter for the following
functions: PRINT (baud rate), CLOCK, PRINT RATE, ALARM, and
CAL when manually entering the calibration data.

Enters a change in parameters when one of the following
functions is selected and flashing: PRINT, CLOCK, PRINT
RATE, ALARM, or CAL.

When held down for 3 seconds, it will clear all logged and
calibration data. All other unit settings remain
unaltered.

Toggles between ON and OFF. OFF will have a 3 second count
down and is used to exit the RUN mode. Note that turning
the unit OFF will NOT reset or erase any of the logged
data.

When the QUESTEMP°II is turned ON, the internal programming
version number is displayed until a key is depressed.

7

DEFAULTS
The factory settings for the QUESTEMP°II are:

CLOCK = U.S. CENTRAL TIME
PRINT baud rate = 1200 BAUD
PRINT RATE = 10 SECONDS
ALARM LEVEL = 38.0°C
CALibration level = 0°C
Temperature units = Celsius

The default settings for the CLOCK, PRINT baud rate, PRINT RATE, and ALARM
LEVEL can be changed by the user. When the unit is powered OFF, the
settings at that time will be stored as the new default values.
Temperature, however, will always default to Celsius and the CALibration
level will be reset to 0°C whenever the unit is RESET (at power OFF, the
last value of CALibration is stored).

DATA LOGGING
In the RUN mode, every ten seconds the QUESTEMP°II will store the ear and
earmold temperature data as well as oral temperature data if the
thermometer is plugged in to the CAL jack. The numbers stored represent
the average value for the previous 10 seconds. The data can be transmitted
to a computer or printer (see the section PRINTING).

The logged information can be cleared from memory by pressing the RESET key
for a count down of 3 seconds. Turning the unit OFF will not effect the
memory. If the unit is put in the RUN mode multiple times without RESET,
data will be stored following the information already in memory.

12.5 hours of data can be logged. Once the memory is full, the unit can no
longer store data but it will continue to operate.

8

PRINTING
All logged information can be sent to a computer or serial printer using an
RS232 serial protocol. The amount of data printed is determined by the
PRINT RATE key on the Questemp°II.

Note that if the unit is in the RUN mode when printing is initiated, the
RUN mode will be canceled and data logging will cease.

COMPUTER CABLES: Connect the meter to a computer using cable #58-867 for a
25 pin serial port. [The standard for a computer's serial port is a 25 pin

or a 9 pin male (pins) connector. Do not connect to the computer's printer
output port which is a 25 pin female (holes) connector. If you have cable
#58-867 but your computer's serial port has only 9 pins, then you may use a
25 to 9 pin converter available at most computer or electronic stores. No
other cables should be used.]

PRINTER CABLES: Connect the meter directly to a serial printer using cable
#58-847. [A serial printer's input is typically a 25 pin female (holes)

connector. Do not use cable #58-847 in conjunction with a computer's
printer cable because that connects into the printer's parallel input port.
Many printers are parallel only and can not accept data from the
Questemp°II. For printers that have both serial and parallel inputs, refer
to the printer's manual for configuring the serial port.]

Note that cables #58-867 and #58-847 are internally wired the same. The
only difference between them is the gender. A straight through 25 pin
gender converter available at most computer or electronic stores can allow
you to use one cable for either a computer or printer.

To initiate printing, use the following sequence:

1. With the unit ON, plug the printer cable into the OUTPUT port of
the QUESTEMP°II.

2. Be sure the desired PRINT RATE is selected (see the key function
PRINT RATE).

3. Press the PRINT/DATA key. If the default baud rate (speed of
data transmission) in the display is not the desired baud rate,
press the PRINT/DATA key a second time and use the ARROW key to
select a new rate.

[If you are downloading to a computer, be sure that it is ready
to accept data prior to moving to step #4.]

4. Press ENTER and the data will be sent. "Prn" will appear in the
display until all of the data has been sent.

To halt printing, simply press the PRINT/DATA key while "Prn" is still in
the display.

COMPUTER DOWNLOADING USING DOS
The MODE and COPY commands can be used directly from the DOS prompt to
download the information. Type the following commands at the DOS prompt.

MODE COMx:baud,N,8,2,P <enter>

After typing the MODE command, the computer should respond with
"RESIDENT PORTION OF MODE LOADED". If the computer responds with
an error message, then there is a good chance that the COM port
selected is not valid.

COPY COMx: filename <enter>

After typing the COPY command, the curser will move to the next
line on the screen and blink. If you receive an error message,
retry the COPY command.

x

refers to which com port is being used. Typically this is COM1 or

COM2.

baud refers to the baud rate and must match the Questemp°II's

settings.

filename

refers to any DOS filename the user makes up.

At this point, the user should have the Questemp°II print. Nothing will
happen on the screen until all of the information has been sent. When the
instrument is done sending the information, the PC will respond with "1
FILE COPIED". There now exists a file called filename in the current
directory in the computer. The user can print this out by typing:
PRINT filename <enter>

COMPUTER DOWNLOADING USING WINDOWS

TM

There is a variety of commercially available software that can easily
accept data from the Questemp°II. These software packages are usually
termed "communications software". Microsoft® WindowsTM has a communications
program under the ACCESSORIES icon called TERMINAL. Instructions on how to
use TERMINAL are located in the Windows

'TM

manuals.

Using any of these communications programs, the user must select the com
(serial) port and the baud rate. The Quest cable must be plugged into the
selected com port and the baud rate on the unit must match the rate
selected in the software. The PC programs also need the following
information in their setup:

data bits = 8 stop bits = 2

parity = none handshaking (flow control) = hardware
For TERMINAL, the settings are found by first selecting SETTINGS, then
COMMUNICATIONS.

PRINTOUT DESCRIPTION

1. Start time refers to the clock time when the RUN mode was initiated.

2. End time refers to the clock time when the last RUN was halted by

either turning the unit OFF or PRINTING.

3. Total run time is the difference between the start and end times. If

there were multiple runs an asterisk will appear after the total run

time indicating that there is a break in the run time data.

4. The current alarm level setting is printed.

5. The current sample rate indicates the amount of time between each set

of data printed.

6. The highest ear temperature logged is printed along with its time of

occurrence.

7. The lowest ear temperature logged is printed along with its time of

occurrence.

8. The calibration value is that of 'ORAL minus EAR' at the time the

calibration sequence was completed. If the unit is calibrated more

than once, each additional value and time will be printed.

9. Ear temperature data (including the calibration offset if the unit was

calibrated) is printed in both Celsius and Fahrenheit.

10. Earmold temperature data is printed in both Celsius and Fahrenheit.

This refers to the second sensor located in the blue earmold and is an

'indicator' of what was occurring in the environment. The values are

not exact ambient temperatures because they may be affected by the

close proximity to the head.

11. If the oral thermometer probe is in the CAL jack and its temperature

is in the range of 32°C to 42°C then the data will be recorded.

Typically, this would provide calibration information of the oral

temperature.

12. Asterisks appear in the alarm column next to the data if alarm had

gone off during that particular time period. Multiple asterisks

appear for each tenth of a degree Celsius above the set alarm level.

(For example: when the alarm is set to 38.0°C, 1 asterisk indicates

38.0°C, 2 asterisks indicates 38.1°C, etc.)

LOW BATTERY
The battery condition should be checked each time before using the
QUESTEMP°II. Pressing the BAT/TEST key will display the actual battery
voltage. When the level falls below 7.5 volts, "Lo" appears in the display
indicating that the battery should be replaced. The unit will continue to
function until the battery falls below 7.2 volts. At that time, the alarm
will sound continuously and the unit will no longer read or store data. If
this occurs, turn the unit OFF and replace the battery before its next use.

Under normal use, the QUESTEMP°II will function for an addition 8 hours
from the time when the battery voltage first hits its "Lo" condition at 7.5
volts.

An on-board 3 volt lithium battery will retain the memory of the
QUESTEMP°II even when the 9 volt battery is removed. This will not,
however, power the unit for operation.

Replace dead batteries with 9 volt ALKALINE, type NEDA 1604A or equivalent.

12

AUDIBLE ALARM
The speaker located in the ear assembly will sound under three conditions.

1. When the 10-second-average temperature in the ear canal exceeds
the set alarm level, the speaker will give two pulses every
second.

2. When the 10-second-average temperature in the ear canal exceeds

0.5°C above the set alarm level, the speaker will give four
pulses every second.

3. When the battery voltage falls below 7.2 volts, the speaker will
sound continuously warning that the unit has stopped reading
temperature data and the battery should be immediately replaced.

III. CALIBRATION

The purpose of calibration is to compensate for the difference between an
individual's ear and body temperatures. The QUESTEMPNII accomplishes this
by taking an oral temperature with the QUESTEMP° CALPROBE I thermometer and
comparing it to the ear temperature. [When taking an oral temperature, the
person should be rested and should not have had anything to eat or drink in
the past 15 minutes. The probe should be kept under the tongue with the
mouth closed.] Although typical oral to ear temperature differentials can
be found over a several degree range, each individual's differential will
remain stable provided that the ambient temperature does not change
drastically from the time of calibration.

At the time of calibration, an offset is added to the ear temperature to
equate it to the oral temperature. This offset will remain in effect until
modified by the next calibration or until the unit is reset. The time and
amount of offset will be listed on the printout.

The calibration procedure should be followed before each use. After the
initial calibration, if the worker's environment changes by more than 10°C,
then the QUESTEMP°II should be recalibrated in the new environment.
Calibration can be done at any time and will not disturb the data logging
in the RUN mode.

!Use the following sequence to calibrate the QUESTEMP°II using the
QUESTEMP° CALPROBE I thermometer.

1. Insert the ear sensor and allow 3 - 5 minutes for it to stabilize
to the correct temperature.

2. Turn the unit ON; RESET it to clear old data if desired; and
press RUN to record calibration data.

3. Place the CALPROBE under the tongue and plug it into the CAL jack
on the unit. Allow 3 - 5 minutes for it to stabilize. (A total
of 6 - 10 minutes for the ear sensor.)

4. Pressing CAL once will display (and update) the oral temperature.

13

The temperature should be stable before continuing.

5. Pressing CAL a second time will blink (and update) the value of
'ORAL minus EAR' in the display. When this value is stable (if
the above sequence and timing was followed, it should be stable
already), press ENTER to complete the calibration sequence.
'CAL' will momentarily appear in the display to indicate that the
'ORAL minus EAR' value was obtained and will now be added as an
offset to the EAR temperature.

!Use this alternative procedure to calibrate the QUESTEMP°II by manually
entering the core temperature. [The core temperature could be obtained
rectally or by infrared tympanic measurement for example.]

1. Insert the ear sensor and allow 6 - 10 minutes for it to
stabilize to the correct temperature.

2. Turn the unit ON; RESET it to clear old data if desired; and
press RUN to record calibration data.

3. Pressing CAL once will display 'o---' indicating that the oral
thermometer is not in place.

4. Pressing CAL a second time will blink '36.0' representing the
core temperature. Adjust this value between 36.0 and 39.0 by
pressing the ARROW key until it displays the core temperature.
Then press ENTER to complete the calibration sequence. 'CAL'
will momentarily appear in the display to indicate that the
entered CORE temperature minus the EAR temperature value was
obtained and will now be added as an offset to the EAR
temperature.

IV. EAR SENSOR USE

EAR SENSOR INSERTION

1) Roll the disposable yellow E.A.R.® foam ear plug, containing a black
protruding tube, back and forth with the fingers until it forms a small
crease-free cylinder. See Figures 1 and 2.

Figure 2.

Figure 3.

2) Using
only light
pressure
to keep
the
E.A.R.®

plug
rolled tight, gently slide it over the sensor of the earmold assembly. The
black tube should slide into the earmold leaving only the yellow foam plug
visible. The sensor should fill the black tube of the E.A.R.® plug with
the tip lying flush with, or just inside of, the outer end of the tube.

3) With the E.A.R.® plug still rolled tight, hold on to the blue earmold
and quickly insert the rolled up plug into the ear canal and hold it in
place until it expands. The yellow portion of the earplug should be
completely contained within the ear canal without any danger of hurting the
inner ear. Fitting is easier if the outer ear is pulled outward and
upwards during insertion as shown in Figure 3. Once the plug has expanded,
pushing or twisting will not improve its fit therefore, if the initial fit
is inadequate, remove the plug and repeat the process.

Figure 4.

4) Maneuver the ear hanger over the ear. The ear hanger will help to hold
the assembly in place throughout the day.

(This procedure may feel awkward at first but it will become very easy with

15

continued usages.)
A properly fit E.A.R.® plug will be comfortable and should hold snug and

secure in the ear canal. It also provides good noise attenuation for those
who would typically use hearing protection.

EAR SENSOR REMOVAL
To remove the ear assembly after use, simply grab the blue earmold, slide
the ear hanger off of the ear, and pull the assembly out from the ear. If
the E.A.R.® plug separates from the assembly and remains in the ear canal,
then simply grab the black tube and pull it out.

The E.A.R.® earplug can easily be removed from the earmold assembly by
gently holding the tip of the plug and sliding it off. Do not squeeze the
middle of the plug to remove or the sensor may be damaged.

Use care when removing or handling the ear sensor assembly. Do not remove
by pulling on the cable and always be careful when handling the temperature
sensor because it can be damaged if mishandled.

E.A.R.® PLUG CARE
The E.A.R.® foam earplugs can be washed with soap and water and reused or
they can simply be thrown away and replaced. (Remove the E.A.R.® plug from
the blue earmold prior to washing.)

If the black tube separates from the yellow foam or if the plug does not
slide properly over the temperature sensor, discard the plug and try
another.

16

V. OPERATION SUMMARY

1) Insert the ear sensor assembly as described in Section IV and allow 5

minutes for the temperature to stabilize. [It may be beneficial to
run the sensor cable under clothing or fasten it to keep it from being
snagged.]

2) Turn the QUESTEMPNII ON. RESET to clear old data if desired. Put the

unit in the RUN mode.

3) Check the battery strength by pressing the BATTERY/TEST key. Replace

the ALKALINE battery if 'Lo' appears in the display.

4) Calibrate the unit following the guidelines in Section III on

CALIBRATION.

5) If your situation requires it, attach the front cover.

6) Clip the QUESTEMPNII housing to your belt or pocket and wear it

throughout the work day or as needed.

7) After use, remove the earplug, print out the data if desired, and turn

the unit OFF.

VI. INDICATORS AND ACTION

ALARM - If the alarm activates, indicating that the body temperature has
exceeded the set alarm level, take appropriate measures to allow the body
to cool itself and properly regulate its temperature. Lowering the work
load, moving into a cooler environment, and drinking cool liquids are all
methods to help cool the body and avoid heat related injuries.

LOW BATTery - If this indicator comes on, replace the 9 volt ALKALINE
battery as soon as possible.

To preserve battery life, be sure to turn the unit OFF when not in use.
