1 INTRODUCTION This instrument is a portable easy use 3½ digit, compact-sized digital thermometer designed to use infrared or K-type thermocouple as input. Meter with Backlit LCD, Auto-hold function and auto power off (15 seconds approx.) feature after releasing MEAS button to extend battery life and with analog signal output function. Temperature[...]

2 WARNING To avoid damage or burns, do not make temperature measurement in microwave ovens. The symbol on the instrument indicates that the operator must refer to an explanation in this manual.[...]

3 CAUTION • Do not use the unit near any device which generates strong electromag- netic radiation or near a static electrical charge, as these may cause errors. • Do not point the lens at the sun or at any other source of strong light. If you do, the sensor may be damaged. • Do not contact the lens against the object whose temperature is to [...]

Use " " switch to turn on or turn off the display Back-Light. 4. Use "°F/°C" switch to select °F or °C the Temperature Range. 5. Connect a type K the[...]

11 MEASUREMENT CONSIDERATIONS 1. Theory of Measurement Every object emits infrared energy in accordance with its temperature. By measuring the amount of this radiant energy, it is possible to determine the temperature of the emitting object. 2. About Infrared Infrared radiation is a form of energy (electromagnetic radiation), and has the property t[...]

12 4. Emissivity All objects emit invisible infrared energy. The amount of energy emitted is proportional to the object's temperature and its ability to emit IR energy. This ability, called emissivity, is based upon the material that the object is made of and its surface finish. Emissivity values range from 0.10 for a very reflective object to[...]

13 MAINTENANCE Battery Replacement Power is supplied by four 1.5V (AAA size) batteries. The " " appears on the LCD display when replacement is needed. To replace the batteries, remove the screw from the back of the meter and lift off the battery cover case. Remove the batteries from battery contacts. Cleaning Periodically wipe the case wi[...]
