Infrared K-Thermometer Model CA876
CHAPTER 1
INTRODUCTION
Warning
• Thermometers are not designed to touch live electrical samples.
• Do not use this instrument with Thermocouple K when voltages
at the sample point exceed 24V
DC
or 24Vrms.
• Do not make temperature measurement in microwave ovens.
Leaking microwaves may result in burns and serious injuries.
• To prevent sensor damage, do not point the sensor lens directly
at the sun or any other source of strong infrared light.
• Do not look directly into the laser beam, and do not aim the laser
beam into eyes.
• 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.
• The Model CA876 is not waterproof or dust-proof. Take necessary
precautions to protect it in wet or dusty environments.
• Repeated sharp flexing can cause the thermocouple leads to
break. To prolong sensor life, avoid sharp bends in the thermo-
couple, especially near the connector.
