SAFETY INFORMATION

A Warning identifies hazardous conditions and procedures that are
dangerous to the user. A Caution identifies conditions and procedures that
can cause damage to the product or the equipment under test.

 Warning

To prevent possible electrical shock, fire, or personal injury:

• Read all safety information before you use the product.

• Carefully read all instructions.

• Use the product only as specified, or the protection supplied by the
product can be compromised.

• Do not use the product around explosive gas, vapor, or in damp or wet
environments.

• Do not look into the laser. Do not point laser directly at persons or
animals or indirectly off reflective surfaces.

• Do not look directly into the laser with optical tools (for example,
binoculars, telescopes, microscopes). Optical tools can focus the laser and
be dangerous to the eye.

• Use the product only as specified, or hazardous laser radiation exposure
can occur.

• Do not use laser viewing glasses as laser protection glasses. Laser viewing
glasses are used only for better visibility of the laser in bright light.

• Do not open the product for reasons other than replacing batteries. The
laser beam is dangerous to eyes. Have the product repaired only through
an approved technical site.

• Verify the product’s operation by measuring on a known temperature
source. Do not use the product if it operates incorrectly or abnormally.

• Do not use the product if it is damaged.

• See emissivity information for actual temperatures. Reflective objects
result in lower than actual temperature measurements. These objects
pose a burn hazard.

• Remove the batteries if the product is not used for an extended period of
time, or if stored in temperatures above 122 °F (50 °C). If the batteries are
not removed, battery leakage can damage the product.

• Replace the batteries when the low battery indicator shows to prevent
incorrect measurements.

• Use only AA alkaline batteries and follow all battery care from the
manufacturer.

• Do not leave the product on or near objects of high temperature.

• For use by competent persons only.

• Have an approved technician repair the product.

W Caution

To prevent personal injury and for safe operation and maintenance of the
product:

• Batteries contain hazardous chemicals that can cause burns or explode. If
exposure to chemicals occurs, clean with water and get medical aid.

• Be sure that the battery polarity is correct to prevent battery leakage.

• Do not short the battery terminals together.

• Keep batteries clean and dry.

To avoid damaging the product under measurement, protect it from the
following:

• EMF (electro-magnetic fields) from arc welders and induction heaters.

• Static electricity.

• Thermal shock (caused by large or abrupt ambient temperature changes
— allow 30 minutes for the product to stabilize before use).

• Do not leave the product on or near objects of high temperature.

Emissivity

MENU BACK TO

ENTER

The emissivity of the surface of a material describes its effectiveness in
emitting energy as thermal radiation. Quantitatively, emissivity is the ratio
of the thermal radiation from a surface to the radiation from an ideal black
surface at the same temperature as given by the Stefan–Boltzmann law. Refer
to Table 1 for the emissivity adjustment.

In measurement mode, emissivity level is shown on the bottom right of the
screen. Emissivity can be changed to values between 0.10-1.00 in menu.

Note: Surfaces with an emissivity <0.60 make reliable and consistent
determination of actual temperatures problematic. The lower the emissivity,
the more potential error is associated with the temperature measurement
calculations of the product, even when emissivity and reflected background
adjustments are attempted and performed properly.

temperature measurement.

MAINTENANCE AND BATTERY REPLACEMENT

Do not use abrasives, isopropyl alcohol, or solvents to clean the case or lens/
window. If used and stored properly, the infrared lens on the product should
require only occasional cleaning (Figure 3.1).

When necessary, to clean the lens:

1. Use a hand-squeeze air pump to gently blow off any dust or debris from
the lens surface.

2. If the lens surface requires additional cleaning, use a clean, fine-fiber cloth,
micro-fiber cloth, or cotton swab dampened with a mild, soapy water
solution. Gently wipe surface of lens to remove smudges and debris.

3. Dry with an absorbent, clean fine-fiber or micro-fiber cloth.

Note: Minor smudges and dirt should not significantly affect the performance
of the product. However, large scratches or the removal of the protective
coating on the infrared lens can affect both image quality and the
temperature measurement accuracy.

To avoid incorrect measurements, replace the batteries when the battery
indicator is low. Use only AA alkaline batteries and follow all battery care
guidelines from the manufacturer. To remove the batteries, first ensure the
product is in OFF position, then unscrew the battery cover. When installing
the batteries, be sure that the battery polarity is correct to prevent battery
leakage. Secure the batteries by screwing the battery cover back in place
(Figure 3.2).
