Page 5: Operation
Operation Meter Power The meter is powered by one 9V battery located in the meter handle. Refer to the Maintenance section for replacement instructions. The displayed battery icon provides battery status. Replace the battery as soon as the battery status icon flashes. Non‐Contact IR Surface Temperature Measurements The IR267 thermometer remotely measures the surface temperature of an object. The emissivity must be properly set to obtain optimum accuracy (see the Emissivity section for details). 1. Hold the meter by the handle grip and pull (and hold) the trigger to power the meter. Use the arrow button to select the O (object/surface) mode if necessary. Scan the surfaces under test; the symbol S (scan) blinks while scanning. Refer to the Field of View section for distance‐to‐target (spot) ratio considerations. 2. Aim the laser pointer approximately a half inch below a specific point of interest. 3. Release the Trigger; the symbol H will appear and the reading (larger digits at center of display) will hold for 10 seconds, after which the meter will automatically shut off. 4. Note that the smaller digits, lower right, reflect the MIN‐MAX‐AVG or DIF reading as selected in the Settings mode. 5. The meter defaults to the settings in use when the meter was last switched OFF. Ambient (Air) Temperature Measurements The IR267 can measure the temperature of ambient air using the recessed temperature sensor located on the front of the meter next to the laser pointer lens. 1. Pull and hold the Trigger to keep the meter powered. 2. Use the UP or DOWN button to select the A (ambient) mode. 3. Hold the meter by its handle grip in the ambient air. 4. When finished, release the Trigger; the symbol H will appear and the ambient air temperature reading will hold for 10 seconds. Contact Thermocouple (Type‐K) Temperature Measurements To avoid electrical shock or personal injury, do not connect the external probe to live electrical circuits. 1. Plug the Type‐K thermocouple sensor into the sub‐miniature jacks at the bottom of the ... - Page 6 Over‐range Indicators (OL and ‐OL) If the temperature measurement exceeds 1112°F (600°C), the thermometer will display OL in place of a temperature reading. If the temperature measurement is below ‐58°F (‐50°C), the thermometer will display ‐OL in place of a temperature reading. Locating Hot or Cold Spots To detect a hot or cold spot, aim the thermometer at a region beyond the target and then scan the entire region in a slow, up/down motion. Aim the laser pointer approximately a half inch below the point of test. Distance to Spot Ratio (Field of View) The meter’s field of view is 12:1 (distance to spot ratio). For example, if the meter is 24 inches from the target (spot), the diameter of the target must be at least 2 inches. Other distances are shown below in the field of view diagram. Note that measurements should normally be made < 2 feet from the target. The meter can measure from further distances but the measurement may be affected by external sources of light. In addition, the spot size may be so large that it encompasses surface areas not intended to be measured. It is necessary to ensure that the size of the target is larger than the spot size. The smaller the target, the closer the distance should be. See the accompanying diagram. IR267‐en‐GB_v1.1 8/16 800.561.8187 information@itm.com www. .com...

Set the low and high alarm limits in the Settings mode. See the Settings mode section for details. The low and/or the high alarms can also be disabled in the Settings mode. When the low or high alarm limits are reached the L (low alarm) or H (high alarm) icon will blink and the alarm buzzer will sound (the buzzer can be disabled in the Settings mode.

Page 8: Settings Mode
Display Mode: MAX‐MIN‐AVG‐DIFF Press the trigger and release. Use M Button to step through MAX‐MIN‐AVG‐DIF display mode icons. Press SET when the desired icon is shown. Pull the trigger to return to the normal operating mode. The display (smaller digits lower right) will reflect the selected mode. Backlight – ON/OFF Press the trigger and release. Use the M button to step to the LitE display. Press the SET button to select oN or oFF. Pull the trigger to return to the normal operating mode. Laser – ON/OFF Pull the trigger and release. Use the M button to step to the LAS display. Use the SET button to select oN or oFF. Pull the trigger to return to the normal operating mode. When the laser is ON, the laser icon will appear on the LCD. HIGH Temperature Alarm Limit Setting Pull the trigger and release. Use the M button to step to Alm H. Use the arrow buttons to set the High Alarm limit. Press the SET button to turn the High Alarm OFF. Pull the trigger to return to the normal operating mode. If the high alarm limit is exceeded when taking measurements, the displayed ALM H will blink and the alarm buzzer will sound (if ‘bU2’ is set to ON). LOW Temperature Alarm Limit Setting Pull the trigger and release. Use the M button to step to Alm L. Use the arrow buttons to set the Low Alarm limit. Press the SET button to turn the Low Alarm OFF. Pull the trigger to return to the normal operating mode. If the low alarm limit is exceeded when taking measurements, the displayed ALM L will blink and the alarm buzzer will sound (if ‘bU2’ is set to ON).. Emissivity Setting Pull the trigger and release. Use the M button to step to the icon. Use the arrow buttons to adjust the emissivity (in 0.01 steps). The emissivity range is 0.05 to 1.00. Pull the trigger to return to the normal operating mode.

Page 9: Measurement Notes
Selecting the Temperature Unit of Measure (°C/°F) Pull the trigger and release. Use the M button to step to °C/°F. Use the SET button to select °C or °F. Pull the trigger to return to the normal operating mode. Setting the Alarm Buzzer ‘bU2’ ON/OFF Pull the trigger and release. Use the M button to step to ‘bU2’. Use the SET button to select ON or OFF. Pull the trigger to return to the normal operating mode. When set to OFF, the Alarm buzzer will not sound in an alarm condition. Measurement Notes 1. The object under test should be larger than the spot (target) size calculated using the field of view diagram. 2. If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking measurements. 3. If an object's surface is highly reflective apply masking tape or flat black paint to the surface before measuring. 4. The meter cannot make accurate measurements through transparent surfaces such as glass. 5. Steam, dust, smoke, etc. can obscure measurements. 6. The meter compensates for deviations in ambient temperature. It can, however, take up to 30 minutes for the meter to adjust to extremely wide ambient temperature changes. 7. To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down motion) until the hot spot is located.
