Safety Information
 Warning
A Warning identifies conditions and actions that pose hazards
to the user. To avoid electrical shock or personal injury, follow
these guidelines:
•Do not point laser directly at eye or indirectly off
reflective surfaces.
•Before using the Thermometer inspect the case. Do not use
the Thermometer if it appears damaged. Look for cracks or
missing plastic.
•Replace the batteries as soon as the battery indicator ( )
appears.
•Do not use the Thermometer if it operates abnormally.
Protection may be impaired. When in doubt, have the
Thermometer serviced.
•Do not operate the Thermometer around explosive gas,
vapor, or dust.
•Do not connect the optional external probe to live electrical
circuits.
•To avoid a burn hazard, remember that highly reflective
objects will often result in lower than actual temperature
measurements.
•Do not use in a manner not specified by this guide or users
manual or the protection supplied by the equipment may be
impaired.
Caution
To avoid damaging the thermometer or the equipment under
test protect them from the following:
• EMF (electro-magnetic fields) from arc welders, induction
heaters, etc.
• Static electricity.
• Thermal shock (caused by large or abrupt ambient
temperature changes- allow 30 minutes for the
Thermometer to stabilize before use).
• Do not leave the Thermometer on or near objects of high
temperature.
