• 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 CA872 is not waterproof or dust-proof. Take necessary precautions to protect it in wet or dusty environments.

CHAPTER 2 PRODUCT FEATURES Description The AEMC Model CA872 is a portable, easy-to-use, compact-sized digi- ® tal infrared thermometer designed for simple one-hand operation. It uses an infrared sensor with a fixed emmisivity of 0.95. The thermometer is simply aimed at the target to be measured without any physical contact (non-contact temperature measurement). An aiming laser enables the user to pin-point the target. The thermometer is supplied with a protective holster and built-in sensor. The CA872 also features a back-light LCD display, an automatic data HOLD function, and Auto-OFF. IR THERMOMETER Model CA872 °C/°F Auto OFF MEAS 1. 3½ digit display 2. Temperature selector 3.

When the button is released, the meter will automatically HOLD (freeze) the last reading on the display for approximately 20 seconds before auto- matically shuting OFF. 2.2.2 °C/°F Button Pressing this button makes the thermometer toggle between °F and °C. The selected temperature type is displayed in the lower right hand corner of the LCD. At power-up, the thermometer is in °C by default. 2.2.3 Back-light Button Press the button to turn the Back-light ON. Press again to turn OFF. 2.2.4 Laser Button Pressing the button turns the laser ON or OFF. The symbol is displayed in the upper left hand corner when the laser is ON. Remove the laser cover before use. The laser is activated when the “MEAS” button is pressed during a mea- surement. NOTE: There is no ON/OFF button. The meter turns ON when the center “MEAS” button is pressed, and will automatically shut OFF after approxi- mately 20 seconds. Infrared Thermometer Model CA872... -

When the target diameter is small, it is Distance to object (mm) important to bring the ther- 1000 mometer closer to the target to ensure that only the target is measured, excluding the surroundings. Remember that the measurement size is one-tenth the dis- tance to the target. For example, if the thermometer is at 10", then the size measured is 1". Infrared Thermometer Model CA872... -

Page 10: Operation
Infrared radiation, which is emitted from the object, is focused into an infra- red radiation sensor through an optical system. This system includes an optical lens, which is transparent to infrared radiation, and a 5.3μm cut off filter. The output signal from the infrared radiation sensor is input to an electronic circuit, along with the output signal from a standard temperature sensor, to calculate the temperature and display it on the meter display. Recommendations before Operating • If the measured surface target diameter is less than 2"/50mm Ø, then place the sensor as close as possible to the target surface (<20"/50cm away). See Field of View (FOV) information under Specifications. • If the target surface is covered with frost or any matter, clean it before taking a measurement. • If the target surface is highly reflective put some matte tape, or matte paint, over it before measuring. • If the thermometer is erratic, or seems not to be measuring properly, make sure that the sensor is clean and not covered by condensation.
