1. SAFETY PRECAUTIONS AND PROCEDURES

This instrument complies with EMC standards related to electronic measuring equipment.
For your own safety and to avoid damaging the instrument follow the procedures
described in this instruction manual and read carefully all notes preceded by this symbol

.

The following symbol is used in this manual:

When this symbol is displayed, the meter is radiating the laser. Always prevent
the laser from radiating to your eyes. Class II laser apparatus according to EN
60825-1.

1.1. PRELIMINARY

• Use the meter only as specified in this manual. An improper use may
damage the instrument or its components

• During usage and storage, keep the meter away from direct sunlight or
strong sources of light, hot objects (70℃/158℉), high temperatures, high

humidity or dust

• After a period of storage in extreme environmental conditions exceeding
the limits mentioned in this manual let the instrument resume normal
operating conditions before using it

• If the meter is moved quickly from a cold to a hot environment, some
condensation may appear on the focal lens. In this case wait for the
condensation to dissipate before taking measurements

• Do not touch the focal lens

• Make sure that the target is larger than the unit’s spot size. The smaller the

target, the closer you should be to it. When accuracy is critical, make sure
the target is at least twice as large as the spot size

• Only the accessories supplied with the instrument guarantee compliance
with the safety standards in force. They must be in good conditions and, if
necessary, replaced with identical ones

• Do not perform measurements beyond the limits specified in chapter 9

• Make sure that the battery is properly installed

• Avoid doing that if you notice anomalous conditions such as breakages,

deformations, fractures, leakages of battery liquid, blind display etc

• This meter is not recommended for use in measuring shiny or polished
metal surfaces (stainless steel, aluminum, etc.)

• The unit cannot measure through transparent surfaces such as glass. It will
measure the surface temperature of the glass instead

• Steam, dust, smoke, etc., Can prevent accurate measurement by
obstructing the unit’s optics

1.2. DURING USE

Read carefully the following recommendations and instructions:

CAUTION

• Be careful not activate the trigger if the symbol is displayed and the laser
output is turned in your direction. A pressure on the trigger activates the
laser. Always prevent the laser from radiating to your eyes.

• If the object under test has a smooth surface reflecting the laser, prevent the
laser from radiating to our eyes.

• Never radiate the laser to inflammable gas

• If the symbol is displayed during use interrupt testing and replace

batteries according to the procedure described under paragraph 8.2

• Use extreme caution when the laser beam is turned on

• Do not let the beam enter your eye, another person’s eye or the eye of an

animal

• Be careful no to let the beam on a reflective surface strike your eye

• Do not allow the laser light beam impinge on any gas which can explode

1.3. AFTER USE

• After using the instrument turn it off

• If you expect not to use the instrument for a long period remove the battery to avoid

leakages of battery liquids which may damage its inner components
