Warnings

To ensure safe operation and service of the meter, follow these instructions. Failure to observe these warnings can result in severe injury or death.

• Do not direct laser beam into eyes, as this can cause permanent eye damage.
• Do not use the meter if the case is damaged in any way.
• Replace the battery as soon as low battery indicator appears.
• Thermometer is NOT intended for use on people or animals.
• Service the meter immediately if it is acting abnormally.
• Avoid using the meter around strong electromagnetic fields.

Caution

? BURN HAZARD. Reflective materials may have a higher actual temperature than the measured temperature. Set emissivity to match the object being measured (see Emissivity section).

Safe Practices

This meter is designed for professionals who understand the hazards associated with their trade. While this meter causes no foreseeable dangers beyond its targeting lasers; the objects being measured, as well as the environment in which they reside, can be hazardous. Common safety practices to follow when operating near temperature critical environments are:

• Follow the manufacturer's maintenance procedures when servicing equipment.
• Before using this meter to determine if an area is safe, verify correct operation by measuring a known temperature value of a comparable object.
• Properly maintain this meter and calibrate it regularly.

Operating Instructions

Temperature Measurement

To measure temperature, aim the meter at the object, pull and hold the trigger (5) for at least 2 seconds. Releasing the trigger initiates Data Hold, displaying "HOLD". If the display shows "OL" or "—OL", the temperature is outside the meter's range.

Targeting

Dual lasers (8) assist in targeting. The distance between the laser spots approximates the diameter of the measurement area. The IR sensor (7) collects data from this area. Measurement areas are larger at greater distances.

The meter has a 12:1 distance-to-spot ratio. Figure 1 illustrates typical measurement spot diameters at various distances:

Figure 1: Distance-to-Spot Ratio (12:1)

• At 6" distance, spot diameter is 0.5" (13 mm)
• At 12" distance, spot diameter is 1" (25 mm)
• At 24" distance, spot diameter is 2" (51 mm)
• At 48" distance, spot diameter is 4" (102 mm)

Targeting Lasers

Press and hold control button (3) to turn targeting lasers (8) on/off. The laser icon (▶️) will be visible when active.

Backlight

Short press control button (3) to toggle the backlight on/off. The backlight icon (?) will be visible when active.

Mode Selections

While measuring, the meter continuously samples the object. After a measurement, repeatedly press the mode control button (1) to cycle through:

• Maximum temperature measured ("MAX").
• Average temperature measured ("AVG").
• Difference between maximum and minimum values ("DIFF").
• Minimum temperature measured ("MIN").

Press the button again to exit the MODE menu.

Settings

Use the SET control button (2) to access adjustable settings. Press SET (2) to enter the menu, then cycle through options:

• Emissivity: Set numerical value to match the surface being measured. The emissivity icon (ε) will flash.
• Units: Switch between °F and °C. The active unit icon (°F or °C) will flash.
• Mute temperature limit alarms: Toggle audible alarms on/off. The audible alarm icon (?) will flash. Hi/Lo icons (⬆️ / ⬇️) are visible when alarms are on, hidden when off.
• High temperature limit setting: Set a numerical value for the high limit. The Hi icon "Hi" will flash.
• Low temperature limit setting: Set a numerical value for the low limit. The Lo icon "Lo" will flash.

Control buttons (1) and (3) adjust settings (up/down) in any menu, select units, toggle alarms, or adjust numerical values.

Emissivity

Emissivity measures a surface's ability to emit thermal energy. Different surfaces have varying efficiencies. The IR5 allows emissivity adjustment from 0.10 to 1.00 for accurate measurements. Shiny surfaces generally have lower emissivity than flat black materials.

The following chart provides estimated emissivity values for various materials. This is for guidance only, as emissivity depends on surface finish, temperature, shape, etc.

Maintenance

Battery Replacement

When the ⚡ indicator is displayed on the LCD, the battery must be replaced.

1. Open the battery compartment (6) by pulling the cover away from the trigger.
2. Remove the exhausted 9V battery and dispose of it properly.
3. Replace with a new 9V battery and secure the compartment cover.

Cleaning

Ensure the meter is off. Wipe with a clean, dry, lint-free cloth. Do not use abrasive cleaners or solvents. Keep the sensor lens clean. Use clean compressed air for loose debris. The lens can be cleaned with a soft cloth or cotton swab dampened with water or rubbing alcohol only. Allow the lens to dry completely before use.

Storage

Remove the battery if the meter will not be used for a prolonged period. Do not expose to high temperatures or humidity. After storage in extreme conditions, allow the meter to return to normal operating conditions before use.
