To setup values for the RUN modes and functions, do the following:
1. Release or unlock the trigger, if necessary.
2. Press the SET button. The SET icon will be activated.
3. Press the RUN/LOG button, if necessary, so that the LOG icon is not activated.
4. Press ACTIVATEto toggle between °C or °F for the display and data output.
5. Press the MODE button to switch between HAL, LAL, TAM, and DOI. Press the
▲or ▼buttons to change the HAL, LAL, TAM, and DOI settings.
6. Press ACTIVATE to activate the HAL, LAL, or TAM.
7. Press ACTIVATE to toggle between DIG (digital)or ANA (analog) outputs.
8. Press the ▲or ▼buttons to set DOI (Digital Output Interval) if DIG was selected.
SET contains six modes: °C/°F, HAL, LAL, TAM, DIG/ANA, and DOI(as shown in
Figure 2-10). In SET, the temperature scale can be set for °C or °F, the HAL, LAL, and
TAM setpoints can be displayed and set, the digital (DIG) or analog (ANA) output
can be selected, and the Digital Output Interval (DOI) can be set. Note the following:
• Press the MODE button to change modes.
• Press the backlight button if a brighter display is needed.
Notes on setting Tamb(Ambient temperature compensation)—The Tamb icon is
activated when the ambient temperature compensation function is active. Targets
that have low emissivities will reflect energy from nearby objects. This additional
reflected energy is added to the target’s own emitted energy and may result in inaccu-
rate readings. In some situations objects near the target (machines, furnaces, or other
heat sources) have a temperature much higher than that of the target. In these situa-
tions it is necessary to compensate for the reflected energy from those objects. Note
that the Tambfeature is disabled if the emissivity is set to 1.00.
To set or change the ambient temperature compensation, complete the following:
1. Go to the RUN loop (pull trigger, press RUN/LOG button, if necessary).
2. Set the emissivity value to 1.0.
3. Press the MODE button until the mode function indicator displays AVG (average
temperature).
4. Pull the trigger and scan across objects and surfaces that face the target. Read the
average temperature value in the MODE value display. This is the value to be
entered as the reflected ambient temperature in Step 7 below. Release the trigger.
5. Press the SET button (do not pull the trigger) to enter the Setup mode
6. Press the MODE button until TAM shows in the mode function indicator.
