645 - 660nm. CLASS II LASER PRODUCT.
Measuring Temperature:
1. Turn the thermometer on by either squeezing the trigger or squeezing the trigger and pushing
the LOCK button.
2. Line up the laser with the target and hold the front of the thermometer eight inches from the tar-
get (spot size will be one inch at this distance).
3. Read the temperature on the LCD.
Turning the laser and Back Light ON and OFF:
1. Squeeze the trigger on the instrument (do not push the LOCK button) and hold it in.
2. Press and hold the SEL button until the laser icon and / or icon is either on the LCD or
not on the LCD (when the icon is on the LCD, the laser and / or backlight is activated).
Each time the SEL button is pressed the mode will change. Available modes are:
Laser and Backlight Off = No icon in the display
Laser On = icon in the display
Backlight On = icon in the display
Laser and Backlight On = icons in the display
Adjusting Emissivity
1. Squeeze the trigger on the instrument and hold it in or push the LOCK button to lock the instru-
ment ON.
2. Push the
E
button and the “
E
=.” will start flashing on the LCD.
3. Push the LOCK button to increase the emissivity or the C/F button to decrease the emissivity.
4. Push the
E
button to save the setting.
Recording Minimum and Maximum Temperatures
1. Squeeze the trigger on the instrument and hold it in or push the LOCK button to lock the instru-
ment ON.
2. Push the REC button to activate the Record function. You will see REC on the LCD.
3. Push the REC button to toggle between the recorded Max and Min temperatures during the
measurement period.
4. Pushing in the REC button and holding it in for 3 seconds deactivates the REC mode (or turn

D. MEASUREMENT TECHNIQUES
Controls and Functions
1.
TRIGGER:
Squeeze the trigger to turn the instrument on. Release the trigger and the last read-
ing is held on the display for approximately 7 seconds. If Bluetooth is on the 377BT will remain
on for 70 seconds after the trigger is released. If the laser is activated it will only come on when
the trigger is pressed.
2.
SEL:
Toggles on and off the laser, backlight and K-type thermocouple measurement functions
of instrument.
Backlight and Laser control - With the trigger held down, press and hold the SEL button to turn
the backlight or laser on and off. Three modes of operation are available, laser and backlight off,
backlight only on, laser only on, backlight and laser on.
Infrared and K-type - With the 377BT on and the trigger pressed down or lock engaged press
the SEL button to toggle between K-type thermocouple input and Infrared input. When K-type is
selected a K-type probe must be inserted in the connector at the bottom front of the thermome-
ter. If a probe is not connected the thermometer will display ‘oPEn’.
3.
LOCK:
This locks the power on and is indicated by the word LOCK on the LCD. You can release
the trigger and the instrument remains on. Pushing the LOCK button once more deactivates the
lock feature and the unit will turn off after 7 seconds (70 seconds if Bluetooth is on).
4.
°F/°C:
This button allows you to view the reading in Fahrenheit of Celsius and is also used to
activate Bluetooth.
F/C Selection - With the thermometer on and the trigger pressed or lock activated press the C/F
button to toggle the display between C or F. The thermometer will power on in the unit of mea-
surement last set when the thermometer automatically powered off.
Bluetooth Control - With the thermometer on and the trigger pressed or lock activated press
and hold the C/F button until ‘Bluetooth on’ is displayed. This activates the Bluetooth feature.
Press and hold the C/F button until ‘Bluetooth oFF’ is displayed and Bluetooth will be deactivat-
ed. When Bluetooth is activated ‘Bluetooth’ will flash in the display.
5.
E
:
This button allows the user to adjust the emissivity setting of the instrument and adjust the
Hi and Low alarm levels.
Emissivity Control - With the thermometer on and the trigger pressed or lock activated press
the
E
button.
E
= will flash and pressing the Lock button will raise the emissivity level and
pressing the C/F button will lower the emissivity level. Once the required level is set press the
E
button to return the thermometer to normal operation. Refer to the chart on page for the emis-
sivity of common objects.
Alarm Control - With the thermometer on and the trigger pressed or lock activated press and
hold the
E
/ button until ‘Alarm High’ is flashing along with the main display. Use the Lock and
C/F button to raise or lower the alarm point. Press the
E
/ button and Alarm Low will flash along
with the main display. Use the Lock and C/F buttons to raise or lower the alarm point. Press the
E
\ button to return to normal operation. When an alarm point is reached the thermometer will
emit a continuous beep.
6.
REC:
This button activates the record function to store minimum and maximum temperatures.
