Using the Features

Basic Features

• To turn the laser on or off: Press and hold the trigger, and then momentarily press the  button.
• To turn the backlight on or off: Press and hold the trigger, and then momentarily press the  button.
• To change between Celsius and Fahrenheit: If the LCD is blank, press and release the trigger.
Momentarily press the °C/°F button.
• To lock the trigger for continuous measurement: If the LCD is blank, press and release the trigger.
Momentarily press the Lock button. Momentarily press the Lock button again to return to normal
measurement. The unit will automatically exit Lock mode after 60 minutes.

Advanced Features

Press the Mode button to access the advanced features. They appear in this order: Emissivity Display
(E), Emissivity Setting (iEh), Maximum (MAX), Minimum (MIN), Difference (dIF), Average (AVG), High
Alarm Limit (HAL), Low Alarm Limit (LAL), and Probe (PRB).
Setting Alarm Points
After selecting the HAL or LAL mode, use the  or  button to set the alarm point. A tone will sound
and the alarm indicator will flash if the temperature is higher than or lower than the corresponding set
point. "HI" or "LOW" will appear with the alarm indicator.
Temperature Probe
To use a K-type thermocouple temperature probe (purchased separately), connect the probe to the
probe jack on the side of the thermometer. Select PRB mode. The probe temperature will appear in
the lower right corner of the display. The temperature detected by the infrared sensor will continue to
appear in the center of the display. You may still use the Mode button to access the other advanced
features, but the probe temperature is displayed only when PRB mode is selected.
Note: The probe will not trip the high alarm and low alarm.
Measurement Review
After the unit shuts off, press Mode to review the measurement:
• MAX — the highest recorded temperature among all of the readings.
• MIN — the lowest recorded temperature among all of the readings.
• dIF — the difference between the maximum and minimum readings.
• AVG — a weighted rolling average of all of the readings.
Note: Values for MAX, MIN, dIF and AVG are reset each time the trigger is pressed.
Note: The AVG feature acts as a filter to eliminate fluctuations from the temperature readings. It is not
an arithmetic mean, but rather a rolling weighted average of the readings that smoothes the data and
excludes sudden spikes.
