The Infrared Laser Thermometer

With this non-contact Thermometer, you can point, shoot and read the Laser by pointing directly at

the target and get an accurate reading. Switch from Fahrenheit to Celsius for instant temperature

readings. Temperature measurement has never been easier. Accuracy is +/- 2%. Response time is

500MS. It’s flashlight shape design has a Storage Case making it compact and portable.

Electronic field: This instrument can measure the radiation point of an electric panel, fuse, dyna-

motor and gearbox and electronic parts.

Do not use product in following fields- EMF (electromagnetic fields), arc welder, induction

heater, etc.

Heating and Air-Condition field: Checks and monitors supply, leakage of pipe and air

stratification.

Automotive field: Check cylinder, heat system & cool system, scan radiator, etc.

Food field: When foods are stored, measures surface temperatures in accordance with HACCP

(Hazard Analysis & Critical Control Point) standards.

Assembly of Infrared Thermometer

1. Slide off the Battery Cover exposing the Battery Cavity (#7). See Figure 2.

2. Insert the DC 9V Battery (not included) into the Battery compartment. DISPOSE OF OLD

BATTERIES PROPERLY. Never put in fire. Contact local Hazard Waste Disposal

authorities for proper guidelines. Replace Battery Cover over the Battery Cavity (#7) after

inserting a new Battery.

SKU 90380 PAGE 3

2. You may set the temperature to Fahrenheit or Celsius by moving the

Switch (#6) on the side of the Infrared Thermometer up or

down as marked. See Figure 1.

3. To obtain accurate temperature readings, you must be sure the distance

from the target is correct. Determine the distance to be measured. The

farther the distance from the target, the larger the spot size.

4. The smaller the object, the closer you should be to it. If you want to get an

accurate reading, you must be sure that the laser reflection is twice as large

as the object.

5. To find a “hot spot”, aim the thermometer outside the area of interest.

Then scan across the object with an up and down motion until you locate

the “hot spot”.

6. When you release the Measure and Laser Button (#5), the last

reading will be held for 7 seconds. The HOLD icon appears on the

screen. See Figure 1.

7. Use masking tape or flat black paint to cover surfaces such as shiny or

polished metal that has low emissive measurements. Take into consideration

the tape and allow more time for the tape to get the same temperature as the

material underneath the tape.

8. If your Battery is low, the LDC screen (#4) will indicate “low battery”.

At this time you will need to replace the Battery (#9). Dispose of the old

Battery. (Contact local Hazard Waste Disposal authorities for proper

guidelines for disposal). See Figure 2.

Maintenance

1. Clean the LDC Protective Cover (#4) with a can of compressed air (not included). Gently brush

remaining dust with a camel hair brush. Carefully wipe the surface with a moist cotton swab

moistened with water or water based glass cleaner.

2. For better and safer performance, keep all parts of this product clean and dry at all times
