Use extreme caution when the laser pointer beam is on.

Do not point the beam toward anyone’s eye or allow the beam to strike the eye from a reflective surface.

Do not use the laser near explosive gases or in other potentially explosive areas.

The range is -58 to 1000°F (-50 to 538°C). The resolution is 0.1°C/F to 200°.

The accuracy is ± 2% of reading or ± 4°F (2°C) whichever is greater.

Note: Accuracy is specified for the ambient temperature range: 64 to 82°F (18 to 28°C). Add ±0.2°F/°F (±0.2°C/°C) outside this range.

The emissivity has a fixed value of 0.95.

The field of view is approximately an 8:1 ratio (D = distance, S = spot).

The laser power is less than 1mW.

The spectral response is 6 to 14 µm (wavelength).

The thermometer has a backlit LCD display with function indicators.

The display update rate is 1 second (approx.).

The operating temperature range is 32°F to 122°F (0°C to 50°C).

The maximum operating humidity is 80% RH.

The thermometer is powered by a 9V battery.

The meter shuts off automatically after 6 seconds.

The weight of the thermometer is 6.35 oz. / 180g.

The dimensions of the thermometer are 3.2 x 1.6 x 6.3″ (82 x 42 x 160mm).

Hold the meter by its Handle Grip and point it toward the surface to be measured.

Pull and hold the red Trigger to turn the meter on and begin testing.

The temperature reading, the ‘SCAN’ icon, the emissivity icon (E=0.95), and the unit of measure will appear. Replace the battery if the display does not light.

While continuing to pull the Trigger, push the laser button to turn on the laser pointer. When the laser is ON, the laser icon will appear on the LCD over the temperature reading. Aim the red beam approximately a half inch above the point of test (pressing the laser button again turns the laser off).

While continuing to pull the Trigger, select the temperature units using the °C or °F button.

While continuing to pull the Trigger, push the backlight button to turn on the LCD backlighting function.

Release the Trigger and the reading will hold for approximately 6 seconds (HOLD will appear on the LCD) and then the meter will automatically shut off.

The meter’s field of view is 8:1. For example, if the meter is 16 inches from the target (spot), the diameter of the target must be at least 2 inches. Other distance ratios are shown below in the field of view diagram:

Distance to Object: 4″ -> Diameter of Spot: 0.5″

Distance to Object: 8″ -> Diameter of Spot: 1″

Distance to Object: 16″ -> Diameter of Spot: 2″

Distance to Object: 32″ -> Diameter of Spot: 4″

Measurements should normally be made less than 2 feet from the target.

The meter can measure from further distances but the measurement may be affected by external sources of light. In addition, the spot size may be so large that it encompasses surface areas not intended to be measured.

The object under test should be larger than the spot (target) size calculated by the field of view diagram.

If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking measurements.

If an object’s surface is highly reflective, apply masking tape or flat black paint to the surface before measuring.

The meter may not make accurate measurements through transparent surfaces such as glass.

Steam, dust, smoke, etc. can obscure measurements.

The meter compensates for deviations in ambient temperature. It can, however, take up to 30 minutes for the meter to adjust to extremely wide ambient temperature changes.

To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down motion) until the hot spot is located.

If the meter gets wet, wipe it off.

Use and store the meter in normal temperatures. Temperature extremes can shorten the life of the electronic parts and distort or melt plastic parts.

Handle the meter gently and carefully. Dropping it can damage the electronic parts or the case.

Wipe the case occasionally with a damp cloth. Do not use chemicals, cleaning solvents, or detergents.

Use only fresh batteries of the recommended size and type. Remove old or weak batteries so they do not leak and damage the unit.

If the meter is to be stored for a long period of time, the batteries should be removed to prevent damage to the unit.

When the low battery symbol appears on the lower left side of the display, replace the meter’s battery (9V).

The battery compartment is located behind the black panel that surrounds the meter’s trigger. Open the compartment by pulling the black panel down from the trigger area. Replace the 9V battery and close the battery compartment cover.
