• 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. Infrared K-Thermometer Model CA876... -

The thermometer is simply aimed at the target to be measured without any physical contact when in the IR mode (non-contact temperature mea- surement). 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.

ALM Lo: The Lo alarm set point is adjusted using the and buttons. When this set point is reached the beeper will sound and ALM Lo will be displayed. MAX: The Max value measured will be displayed during measurement. While in the MAX mode and when measuring, the MODE button will toggle the mea- surement between MAX – MIN – Present reading – MAX. MIN: The Min value measured will be displayed during measurement. While in the MIN mode and when measuring, the MODE button will toggle the mea- surement between MIN – Present reading – MAX – MIN. K: The lower display will indicate the reading from the K-type thermocouple. NOTE: If the thermometer is OFF, pressing the “MEAS” button for more than 4 seconds will set the thermometer in the MIN/MAX record mode when pow- ered up. Infrared K-Thermometer Model CA876... -

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. ε In the settings , ALM Hi and ALM Lo, the button decreases the numeri- cal value displayed in the lower smaller display area. If held down, the value change will decrease in speed. 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 15 to 20 seconds. Infrared K-Thermometer Model CA876... -

Emissivity values range from 0.10 for a very reflective object to 1.00 for a black body. Factory set emissivity value of 0.95 will cover 90-95% of typical applications. If frost or other material/substance covers the measured surface, clean it to expose the surface. If the surface to be measured is highly reflective, apply dull masking tape or matte black paint over the surface. If the ther- mometer seems to be giving incorrect readings, check the front sensor. There may be condensation or debris obstructing the sensor. Only clean per instructions. Infrared K-Thermometer Model CA876... -
Page 13: Recommendations Before Operating
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.

6. If the measured temperature is outside the measurement range, will be displayed. 7. The thermometer will continue measuring as long as the MEAS button is pressed. When the button is released the measurement will be held in the display for 15-20 seconds. HOLD is displayed in the lower left- hand corner of the display. 8. The IR thermometer will shut OFF automatically after 15-20 seconds. K-Thermocouple Operation 1. Connect the K-thermocouple to the instrument input. 2. Press MEAS to turn the thermometer ON. 3. Press the MODE button (six times) to enter the thermocouple mode. K will be displayed in lower right hand corner of the display. 4. Put the thermocouple near or on the sample tested. 5. Press MEAS button to measure. Thermocouples need a certain time to respond. Take the reading when the measurement has stabilized. The reading is displayed in the smaller lower display in front of the K symbol. The main larger display is the IR temperature reading. 6. The thermometer will continue measuring as long as the MEAS button is pressed. When the button is released, the measurement will be held in the display for 15-20 seconds.
