Save and exit (automatic shut off)

 

Press MENU to save the setup and “SAVE” will be displayed

(fig.8.14). All setup will be saved and thermometer will automatically shut off (fig.8.15).

After activating setup menu, users may select specific functions(F1/F2/F3/F4) directly for specific setting.

New setup will not be saved if the thermometer is shut off

[fig 8.14] unexpectedly during the procedure of setting.

After activating setup menu, the thermometer is unable to measure temperature. There will be no response when pressing measurement button.

!

Notice

Temperature reading under human body mode is obtained from dynamic compensation of environmental temperature and forehead surface temperature.

Object temperature mode is to test surface temperature of an object. The temperature obtained from the forehead under this mode is merely temperature of the skin surface but not core body temperature.

Deviation setting is able to adjust measurement value from 0°C to 3.0°C according to testing distance, surrounding temperature, skin difference, etc. Defaulted value is 0.8°C.

For example: if the tested body temperature is 36.2°C while the temperature is supposed to be 37.0°C, “F-4” to set up the value and adjust to 1.6°C, then the measurement value will be 37.0°C.

6 MEASUREMENT

6.1

Body temperature

Press measurement button to turn on thermometer and it displays boot screen (fig.9.1). After POST and two beeps, it will display value of last reading and be ready for measurement (fig.9.2).

Make sure the thermometer is under body mode.

   

Keep distance at 5cm to 8cm from upper eyebrows to the probe (fig.9.3). Press measurement button and when it gives a “beep” measurement is finished and value will be displayed (fig.9.4). If measurement value is exceeding alarm value (Defaulted value is

38°C), it gives 3 successive beeps as an indication.

 

[fig 9.1]

 

[fig 9.2]

After measurement, if the thermometer is idle for

30 seconds, it will display “OFF” (fig.9.5) and gives a

“beep” and shut off automatically.

[fig 9.3] [fig 9.4]

!

Notice

Keep the sensor and probe cavity clean before and after use.

To ensure the accuracy of measurement, it is recommended to start measurement ten minutes after carrying the thermometer to a new environment.

 

[fig 9.5]

Wait for 10 minutes to measure body temperature after measuring extremely high temperature or extremely low temperature.

Wait for 5 minutes to start a measurement when the measuring target (object or human) is from an environment with enormous difference in temperature.

Breeze, water, sweating, cosmetic on the forehead may affect measurement. Do not measure body temperature 30 minutes after exercise, bath or meals.

6.2

Object temperature

Press measurement button to turn on thermometer

(fig.9.6).

Make sure the thermometer is under object mode.

 

Keep vertical distance at 5cm to 8cm from object to measurement probe. Press measurement button and when it gives a “beep” measurement is finished and value will be displayed (fig.9.7).

[fig 9.6]

After measurement, if the thermometer is idle for 30 seconds, it will display “OFF” (fig.9.8) and gives a beep and shuts off automatically.

!

Notice

The value under this mode is object surface temperature instead of core temperature.

The defaulted infrared emissivity is 0.95. The reading will be deviated from the real temperature according to different emissivity. For example, the reading on stainless steel will be obviously lower than real temperature. BE CAUTIOUS FOR SCALDING.

[fig 9.8]

6.3

Exceeding measurement range

Body mode: When measurement value is lower than 35.5ºC, it displays “Lo” (fig.9.9) and gives 4 successive beeps. When measurement value is higher than 42.9 ºC, it displays Hi (fig.9.10) and gives 4 successive beeps.

     

[fig 9.9]

 

[fig 9.10]

 

[fig 9.11]

Object mode: When measurement value is lower than 0ºC, it displays “Lo” (fig.9.11) and gives 4 successive beeps. When measurement value is higher than 118.0ºC, it displays “Hi” (fig.9.12) and gives 4 successive beeps.

!

Notice

[fig 9.12] [fig 9.13]

When surrounding temperature is lower than

10.0ºC or higher than 40.0ºC, it displays “Err” (fig.9.13). Measurement is not possible and hence accuracy is not assured.

7 BATTERY REPLACEMENT

Open the battery lid and take out the exhausted battery.

Put in 2x AA alkaline batteries and shut the battery lid.

After new battery is installed, thermometer will give 2 successive beeps. If no beeps are heard, check if the positive and negative pole are correct (see fig.10.1).

 

[fig 10.1]

!

Notice

Take out battery in case the thermometer is not used for long period. Do not discard the battery in a fire. Dispose of your batteries according to local regulations.

8 MAINTENANCE & TIPS

Make sure the sensor and probe cavity are clean otherwise accuracy will be affected.

Cleaning method for probe:

Use a cotton stick or soft cloth with water or alcohol to wipe the casing.

Use a cotton stick or soft cloth with alcohol to wipe the sensor surface or probe cavity gently. Do not use thermometer before alcohol is vaporized.

Read this manual book thoroughly before use. Make sure that the batteries are well installed.

It is not recommended to put the thermometer in any liquid or expose to strong sunlight or extremely low temperature.

Strong impact to the product will cause damage.

Do not dismantle this thermometer by yourself.

Keep the thermometer away from children’s reach.

Do not use the thermometer in cases of strong magnetic intereference.

The measurement results can fluctuate due to improper measurement procedures.

Please practice adequate measurement in order to improve your skill.

The measurement results cannot supersede a doctor’s diagnosis.

Special maintenance is not necessary for this thermometer. Please contact distributor or manufacturer in case of malfunction.

9 TROUBLESHOOTING

DESCRIPTION

LCD display

“Lo” or “Hi”

SOLUTION

Breeze, water, sweating, cosmetic on the forehead may affect measurement.

Check deviation value setting. Defaulted value is 0.8°C.

If the environmental temperature changes enormously or if the thermometer is used directly from high temperature to very low temperature, the measurement difference will happen. The thermometer should be kept in a relative stable environment for 10 minutes to obtain heat balance before starting a new measurement. Ensure measurement distance is

5cm to 8cm.

No response when pressing measurement button

No or improper display

No beeper

Take out and reassemble battery.

Check if the thermometer is under menu setup. In procedure of menu setting, thermometer is unable to measure and therefore no response.

Take out battery and install battery again.

Check if beeper is switched off.
