User Manual Dual Laser InfraRed (IR) Thermometer MODEL 42512
Introduction Congratulations on your purchase of the Model 42512 IR Thermometer. This Infrared thermometer o o measures and displays non-contact temperature readings up to 1832 F (1000 C). At 30”, built-in dual lasers converge to 1” target spot to insure accurate targeting and temperature measurement. The adjustable emissivity feature allows the IR thermometer to measure the temperature of virtually any surface. Proper use and care of this meter will provide years of reliable service.

Operating Instructions Temperature Measurements 1. Hold the meter by its handle and point it toward the surface to be measured. 2. Pull and hold the trigger to turn the meter on and begin testing. The temperature reading, MAX temperature reading, the ‘SCAN’ icon, the emissivity value, and the unit of measure will appear. 3. Release the Trigger and the reading will hold for approximately 7 seconds (HOLD will appear on the LCD) after which the meter will automatically shut off.
MAX (maximum) temperature display The highest reading encountered during a single measurement scan is displayed in the MAX display Backlight 1. Press and release the Trigger 2. While HOLD is on the display, press the backlight button off. once to turn on the backlight on or 3. The backlight will illuminate in the LCD when the feature is enabled. 4. The status of the backlight will be stored in memory and will remain as the “turn-on” condition until changed. 5.
Lock feature The LOCK feature disables the Auto Power Off feature for the period of use when selected. The feature is useful for long term temperature monitoring and hands free use. The meter will revert to auto power off if the trigger is pressed during a locked scan. Over-range Indication If the temperature measurement exceeds the specified temperature range, the thermometer will display dashes in place of a temperature reading.
Field of View The meter’s field of view is 30:1. For example, if the meter is 75cm from the target (spot), the diameter of the target must be greater than 2.5cm. Other distances are shown in the field of view diagram. Measurements should normally be made as close as possible to the device under test. The meter can measure from moderate distances but the measurement may be affected by external sources of light.
