Operating Instructions
Power ON and OFF
1. Gentlypullthetriggertoturnthethermometeron.TheLCD
display and the backlight will turn on.
2. The thermometer will automatically shut off after 15 seconds
of inactivity.
Manual Measurement
1. Pull and hold the trigger after aiming at the target. The icon
willash,indicatingthatthetargettemperatureisbeingmeasured.
2. When the trigger is released, the icon will disappear and the
icon will appear indicating that measurement has stopped
and the last measured temperature will remain on-screen until
another measurement is taken or the unit turns off.
Continuous Temperature Measurement (Trigger Lock)
T he instrument allows for a continuous temperature measurement time to
be set from 1 minute to 5 hours. Refer to Trigger Lock Setup for details.
Note: This function is applicable for processes that require regular moni-
toring of temperature.
1. Once the trigger lock function is enabled, the icon will appear on
thedisplayandtheSCANiconwillashwhenthetriggerispressed.
2. Pull the trigger again to stop measuring and both the andSCAN
iconswilldisappearandtheHOLDiconwillappear.Thethermometer
will now hold the last measured value until the unit turns off after 15
seconds of inactivity or until testing is resumed.
3. When the continuous temperature measurement time is reached, the
thermometer will automatically power off and save the last measured
value. You can view the last measured value by pulling the trigger.
Note: The last measured value is cleared when a new test scan is started.

Setting the High Temperature Alarm
Press the SET button once to enter the high alarm limit setup. Press
the button to toggle between alarm preset values as indicated by
P1-P5.UsetheUP or DOWN buttons to set the temperature value within
selected the preset. Press the UP or DOWN buttons to add or subtract by
1 temperature value. Hold the UP or DOWN buttons to add or subtract by
10 temperature values. The instrument will exit the setup after 10 seconds
of inactivity or if the trigger is pulled at any time.
Setting the Low Temperature Alarm
Press the SET button twice to enter the low alarm limit setup. The meter
willautomaticallydefaulttothepreviouslyselectedpreset.Usethe

Appendix: Emissivity Chart
Emissivity is a term used to describe the energy-emitting characteristics
ofmaterials.Most(90%oftypicalapplications)organicmaterialsand
painted or oxidized surfaces have an emissivity of 0.95.
Inaccurate readings will result from measuring shiny or polished metal
surfaces. To compensate, cover the surface to be measured with masking
tapeoratblackpaint.Allowtimeforthetapetoreachthesame
temperatureasthematerialunderneathit.Measurethetemperatureofthe
tape or painted surface.
