Battery Installation & Replacement

Two new pre-installed 1.5V AAA batteries come inside your Lasergrip. Follow the steps below to properly set up your Lasergrip.

1. For first-time use, pull the insulation strip out of the battery compartment and discard. [Figure 1.1]
   
   [Figure 1.1]
   NOTE: You do not need to remove the batteries to pull out the insulation strip.
2. Open the battery compartment, and make sure the batteries are correctly placed inside the battery terminals. [Figure 1.2]
   
   [Figure 1.2]
   
3. Close the battery compartment. [Figure 1.3 ]
   

NOTE:

• The low battery indicator will appear on the display when the power is running low. Immediately replace the battery when the icon appears.
• Remove the batteries before storing if the Lasergrip is not being used for a long period of time.

Operation

Surface Temperature Measurement

NOTE:

• The Lasergrip only measures surface temperature, and cannot accurately measure internal temperature.
• The Lasergrip cannot measure the temperature of objects behind glass or other transparent materials, and may be inaccurate in areas with steam, dust, or any other particles in the air.

1. Press the trigger to turn on the Lasergrip.
   NOTE: Make sure the insulation strip is removed from the battery compartment.
2. Point the Lasergrip towards a surface.
3. Press and hold the trigger and the laser will activate for aiming guidance.
   NOTE:
   • Optionally, press to turn on the laser.
   • To scan live temperature readings on a surface, keep holding the trigger as you move the Lasergrip.
4. Release the trigger and the LCD display will show the calculated temperature.
5. Press the trigger again to take another measurement.

NOTE: The Lasergrip LCD will display "HI" when the measured temperature is higher than the measurable range, and will display "LO" when the measured temperature is lower than the measurable range.

Sensor Care

• Avoid touching the sensor. This will interfere with measurements.
• To clean the sensor, wipe with a soft cloth or cotton swab. Do not wipe or clean with other materials.

Unit Conversion

To change the temperature unit, press while the Lasergrip is on.

Laser Activation

To turn the laser on/off, press while the Lasergrip is on.

Backlight Display

To turn the backlight display on/off, press while the Lasergrip is on.

Emissivity/Maximum Temperature Mode

To adjust the emissivity value before measurement, press , then press and to change to the desired value.

NOTE:

• Press and for more than 1 second to quickly adjust the emissivity value.
• You can refer to the emissivity reference chart for standard surface emissivity values.

To change to Max Temperature Mode, press once more.

Distance-to-Spot Ratio

The distance-to-spot ratio (D:S) determines the accuracy of the reading taken by the Lasergrip. The smaller the surface you want to measure, the closer you should hold the Lasergrip to the surface.

The Lasergrip's 12:1 D:S ratio means that when held 12 inches from a surface, the Lasergrip measures a "spot" that is 1 inch in diameter. When the Lasergrip is held 24 inches away, the "spot" will be 2 inches, and so on. The greater the distance, the larger the measured surface area.

For best results, make sure the surface that you want to measure is at least twice the size of the spot the Lasergrip is measuring. If the measured spot is too small, the Lasergrip's reading will be less accurate. The Lasergrip's reading may also be less accurate when measuring a larger surface because the temperature will vary more over a larger surface.

The recommended distance to hold the Lasergrip from the measured surface is 14.17 in / 36 cm. This will measure a "spot" of 1.18 in / 3 cm in diameter.

Distance-to-Spot (D:S) Ratio = 12:1

Emissivity

Emissivity measures how well a surface emits thermal or infrared energy, ranging from 0.00–1.00. Non-reflective surfaces have a higher emissivity (closer to 1) and reflective surfaces have a lower emissivity (closer to 0). The Lasergrip is meant for high-emissivity surfaces, and may not accurately measure polished, shiny, or reflective surfaces.

To take accurate temperature measurements of reflective surfaces with low emissivity, adjust the emissivity value before measurement using the Emissivity Reference Chart. Optionally, place a strip of masking tape over the surface and allow it to adjust to the surface temperature for 30 minutes. Then, measure the taped section to increase temperature reading accuracy.

Important Safety Information

READ AND SAVE THESE INSTRUCTIONS
Please read and follow all instructions and safety guidelines in this manual.

• Do not point the Lasergrip at another person or animal.
• Do not point the Lasergrip at an aircraft.
• Avoid any eye contact with the laser. Laser radiation may cause eye damage.
• Do not allow children to operate the Lasergrip.
• Remove batteries for storage if the device is not being used for a prolonged period of time.
• Do not use the Lasergrip to determine whether a highly reflective surface is safe to touch. Temperature measurement may be inaccurate, which may cause burns.
• Keep the Lasergrip away from objects that produce strong electromagnetic fields, such as arc welders and induction heaters.
• The Lasergrip measures surface temperature, not internal temperature. Do not use the Lasergrip to measure body temperature.
• Do not expose the Lasergrip to direct sources of heat for extended periods of time.
• Do not use the Lasergrip near explosive gases or other potentially explosive areas.
• Household use only.

THIS DEVICE PRODUCES CLASS 2 LASER RADIATION. USE EXTREME CAUTION WHEN IN USE. DO NOT LOOK INTO DIRECT OR REFLECTED LASER LIGHT BEAM OR VIEW BEAM WITH OPTICAL INSTRUMENTS. DO NOT AIM LASER AT ANOTHER PERSON OR ANIMAL. LASER RADIATION MAY DAMAGE YOUR EYE. DO NOT DISASSEMBLE.

READ ALL OF THE INSTRUCTIONS IN THIS MANUAL. FAILURE TO COMPLY WITH THE INSTRUCTIONS IN THIS MANUAL, OR USE OF THE DEVICE IN WAYS OTHER THAN THE ONES MENTIONED IN THIS MANUAL, MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

The device certification information is labeled directly on the device. The sticker is located on the left side of the Lasergrip.

The device warning and aperture safety information are also labeled directly on the device; the sticker is located on the right side of the Lasergrip.
Any updates to the product information (date of manufacturing and manufacturer address) will be added as adhesive overlays.
