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 the 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 the low battery indicator appears.
• The 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 with the IR5, aim the meter at the object to be measured, pull the trigger 5, and hold it depressed for at least 2 seconds. Releasing the trigger initiates  Data Hold, “HOLD” will show on the display, and the measurement will be held on the display. If the display shows “OL” or “–OL” following a measurement, this indicates that the surface temperature of the object being measured is either above or below the measurement range of the meter.

TARGETING
The IR5 features dual lasers 8 to assist in targeting the measurement area. The distance between the two laser spots on the surface of the object being measured approximates the diameter of the circular measurement area from which the infrared sensor is collecting data. Measurement areas located far away from the meter will be larger than those close to the meter.

The meter is configured with a 12:1 optical resolution (distance-to-spot ratio). The distance-to-spot ratio defines the size of the measurement area relative to the distance between the measurement location and the IR sensor 7. Typical diameters of the measurement area as a function of the distance between the meter and the target area are depicted below for 12:1 optical systems (Fig. 1).

TARGETING LASERS
The targeting lasers 8 may be turned on/off by long presses of control button 3. When on, the laser icon “ ” will be visible on the display.

BACKLIGHT
The backlight may be toggled on/off by short presses of the control button 3. When on, the backlight icon will be visible on the display.

MODE SELECTIONS
When measuring temperature the meter continuously samples the object being measured. Following a measurement, repeatedly press the mode control button 1 to cycle  through:

• the maximum temperature value measured (“MAX”).
• the average value measured (“AVG”).
• the difference between maximum and minimum values measured (“DIFF”).
• the minimum value measured (“MIN”).
• Press once more to exit the MODE menu.

SETTINGS
User adjustable settings may be defined using the SET control button 2.
Press SET 2 to enter the settings menu, subsequent presses of the SET cycle through the following list of options:

• emissivity: set the numerical value of the emissivity to match the surface being measured (see EMISSIVITY section below). When in this setting the emissivity icon will flash on the display.
• units: Switch between °F (Fahrenheit) and °C (Celsius). When in this setting the “°F” or “°C” icon will flash on the display, indicating the temperature scale that is currently active.
• mute temperature limit alarms: (turn audible limit alarms on/off). When in this setting the audible icon “ “will flash on the display. When on, the high /low  icons will be visible, and when off they will not be visible.
• high-temperature limit setting: assign a numerical value to the high-temperature limit. When in this setting, the high icon will flash on the display.
• low-temperature limit setting: assign a numerical value to the low-temperature limit. When in this setting, the low icon “ Lo ” will flash on the display.

When in any setting, control buttons 1 and 3 function as up/down to adjust settings and they may be used to select units, turn alarms on or off, or adjust the numerical values of the respective parameters up or down.

EMISSIVITY
Emissivity is a measure of the ability of a surface to emit thermal energy by radiation. Different types of surfaces (metals, masonry, wood, etc.) emit thermal energy through radiation at different efficiencies. Accordingly, these materials have different emissivity coefficients which must be considered in order to make accurate measurements with an infrared thermometer.

Emissivity on the IR5 may be adjusted from 0.10 to 1.00 to enable accurate measurement of the temperature of most types of materials. Generally speaking, shiny bright surfaces such as chrome, whiteboards, etc. exhibit lower emissivity than flat black materials.
For guidance only, the chart below may be used to estimate emissivity for many different types of materials. However, the emissivity of surfaces is dependent upon many parameters such as surface finish, temperature, the shape of the object, etc.

This chart should be used for guidance only.

MAINTENANCE

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

1. Open battery compartment 6 by pulling the battery compartment cover at the indentations away from the trigger.
2. Remove the exhausted 9V battery and dispose of it appropriately.
3. Replace the 9V battery and return the battery compartment cover, ensuring that it locks into place.

CLEANING
Be sure the meter is turned off and wipe with a clean, dry lint-free cloth. Do not use abrasive cleaners or solvents. Take care to keep the sensor lens clean at all times. If required,  loose debris may be removed from the lens using clean compressed air. The lens may also be cleaned using a soft cloth or cotton swab with water or rubbing alcohol only. The lens must be allowed to completely dry prior to use.

STORAGE

Remove the battery when the meter is not in use for a prolonged period of time. Do not expose to high temperatures or humidity. After a period of storage in extreme conditions exceeding the limits mentioned in the General Specifications section, allow the meter to return to normal operating conditions before use.
