This manual covers operation of the MasterCool 52224-D 12:1 multi-laser infrared thermometer, including measurement, alarms, batteries and specifications.
The MasterCool 52224-D is a 12:1 multi-laser infrared thermometer. Aim the lens at the target and press the Meas. key to display the surface temperature, and use the Mode key to scroll through display functions. Emissivity defaults to 0.95 and can be set from 0.10 to 1, with MAX, MIN, DIF and AVG modes, HAL and LAL alarms, lock mode, °C/°F transfer, backlight and laser on/off control.
The thermometer automatically shuts off after more than 60 seconds idle and uses AAA 1.5V batteries, with battery OK, low and exhausted indications. It displays Hi/Lo, Er2, Er3 and other error messages, and the lens should be cleaned only with a soft cloth or cotton swab with water or medical alcohol and allowed to dry fully before use. Keep the device away from children, do not use it for safety related applications, and do not look directly into the laser beam.
