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.
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.
4 SPECIFICATIONS GENERAL Display: 3½ digit liquid crystal display (LCD) with maximum reading of 1999. Overrange : (OL) or (-OL) is displayed. Low battery indication: the " " is displayed when the battery voltage drops below the operating level.
5 Infrared Radiation ELECTRICAL Temperature Range: 0°F to 500°F, -20°C to 260°C. Display Resolution: 1°F / 1°C. Accuracy: ±3% of reading or ±6°F/3°C, whichever is greater @ 64.4 to 82.4°F (@ 18 to 28°C) ambient operating temperature. Temperature Coefficient: ±0.
6 Spot size increases with distance from the probe tip as shown.
7 K-type thermocouple ELECTRICAL Temperature Range: -58°F to 1999°F, -50°C to 1300°C. Display Resolution: 1°F / 1°C. Accuracy: Accuracy is specified for operating temperatures over the range of 64°F to 83°F (18°C to 28°C), for 1 year, not including thermocouple error.
8 OPERATING INSTRUCTIONS MEAS (MEASURE) Button Depress MEAS button to turn on the meter for measuring temperature. Releasing MEAS button to stop measuring temperature and automatically hold the display reading, the meter turns off automatically after 15 seconds.
OPERATION Infrared Radiation Measurements 1. When the power is off, pressing the MEAS button turns on the power. 2. Use "IR / K" switch to select IR Temperature function. 3. Use " " switch to turn on or turn off the display Back-Light.
10 K-type thermocouple Measurements 1. When the power is off, pressing the MEAS button turns on the power. 2. Use "IR / K" switch to select K Temperature function. 3. Use " " switch to turn on or turn off the display Back-Light. 4.
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.
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.
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.
