CHAPTER 1
INTRODUCTION
Warning
• Thermometers are not designed to touch live electrical sam-
ples.
• To prevent sensor damage, do not point the sensor lens directly
at the sun or any other source of strong infrared light.
• Do not place the infrared thermometer directly on or close to
objects at temperatures exceeding 158°F (70°C)
• To prevent measurement errors, do not expose the thermom-
eter to strong electrical or electromagnetic fields.
• To prevent sensor damage and erroneous readings, do not
put the sensor lens into contact with any body or foreign/loose
material when measuring. Keep the sensor perfectly clean.
• Do not touch the sensor when taking measurements as it may
affect the readings.
• When the meter is exposed to sudden temperature changes
(hot or cold), allow 20 minutes of stabilization before taking a
reading.
• Be certain there is no condensation on the lens prior to taking
measurements. Allow 10 minutes for condensation to dissipate
as needed.
