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 24VDC 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 thermometer to strong electrical or electromagnetic elds.
• 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 exing can cause the thermocouple leads to
break. To prolong sensor life, avoid sharp bends in the thermocouple, especially near the connector.

the operator must refer to the user manual for instructions before
operating the instrument. In a manual, the symbol preceding
instructions indicates that if the instructions are not followed, bodily
injury, installation/sample and product damage may result.
Laser Radiation - DO NOT look into the laser beam.
Laser Output < 0.5mW, 670nm wavelength.
1.2 Receiving Your Shipment
Upon receiving your shipment, make sure that the contents are consistent
with the packing list. Notify your distributor of any missing items. If the
equipment appears to be damaged, le a claim immediately with the carrier and notify your distributor at once, giving a detailed description of any
damage. Save the damaged packing container to substantiate your claim.

PRODUCT FEATURES
2.1 Description
The AEMC® Model CA876 is a portable, easy-to-use, compact-sized digi-
tal infrared and K-thermocouple input thermometer, designed for simple
one-hand operation. It uses an infrared sensor with a user adjustable
emmisivity setting.
The thermometer is simply aimed at the target to be measured without
any physical contact when in the IR mode (non-contact temperature measurement). An aiming laser enables the user to pinpoint the target. The
K-type thermocouple input may also be used. The thermometer includes a
programmable Alarm, which triggers on Hi or Lo, and a MIN or MAX Hold
function. The thermometer is supplied with a protective holster, built-in
sensor, and a K-type bead thermocouple. It also features a back-light LCD
display, an automatic data HOLD function, and Auto-OFF.
