Used to change temperature units from Fahrenheit to
Celsius.
When setting emissivity ( ), high alarm value (HAL),
or low alarm value (LAL), press this
decrease the value to be set.
4 MODE Button
• Each time you pull the trigger (for > 1 sec) to take
measurements, the thermometer records the maximum
(MAX), minimum (MIN), the differential (DIF) between the
maximum and the minimum, and the average (AVG) of
all readings taken during this pull. These data are stored
in memory and can be recalled with the MODE button
until you pull the trigger (> 1 sec) once more. When you
pull the trigger (> 1 sec) once more, all these data will
be erased from memory and the thermometer will start
a new recording.
• When you pull and hold the trigger, the reading on
the main display will update every second with the
temperature of the target surface, and when you release
the trigger, the last reading is locked until you take new
measurement or the thermometer turns off automatically.
• You can press the MODE button to display the maximum
(MAX), average (AVG), minimum (MIN), difference
(DIF), low alarm value (LAL) and high alarm value
(HAL) sequentially on the bottom display. The process is
illustrated in Figure A.
NOTE:
To read value correctly, please observe the bottom display
carefully to see whether the negative sign „-" and the
decimal point appear.
After you disconnect the battery from the thermometer for
a while, all the settings will be restored to default values
and all the recorded measurement data will be erased
from memory.
How to Set the Thermometer
Setting the High Alarm and Low Alarm
1. After the thermometer has been turned on, press and hold
button to
down the MODE button until the symbol
release the button.
2. Press the MODE button until LAL appears and flashes,
now the present low alarm value is being shown on the
bottom display.
3. Press the
increase the low alarm value.
NOTE: Press and hold down the
fast adjustment.
4. After setting the low alarm value, press the MODE button.
HAL flashes and the high alarm value is shown on the
bottom display. Use the same method of Step 3 to adjust the
high alarm value.
5. If the temperature of target surface reaches or is lower
than the low alarm value,
flash and the built-in buzzer will beep and the LCD will
momentarily turn blue when you press and hold the trigger.
If the temperature of target surface reaches or is higher than
the high alarm value,
the buzzer will beep and the LCD will momentarily turn red
when you press and hold the trigger.
6. At any time, you can press and hold down the MODE button
to exit setting mode.
NOTE:
Alarm accuracy is ± 1°C (or ± 2°F).
The low and high alarm values can be set only within the
thermometer's measurement range.
The high alarm value must be higher than the low
alarm value.
Emissivity/ Setting Emissivity
Emissivity describes the energy-emitting characteristics of
materials. Most (90% of typical applications) organic materials
or non-shiny surfaces have an emissivity of 0.95 in the
default setting. Inaccurate readings will result from measuring
shiny or polished metal surfaces. To compensate, cover
the surface to be measured with masking tape or flat paint.
Allow the tape or paint to reach the same temperature as the
surface it is covering. Then measure the temperature of the
covered surface.
