- Page 2 . This product is designed to measure temperature using a non-contact method. Do not use it for other purposes. . Read this manual thoroughly before using SK-8950. Keep the manual in a safe place for future references whenever necessary. WARNING Beware of explosion! SK-8950 is not explosion-proof.
- Page 3 - Do not touch the measurement window with a sharp or hard object. Doing so may damage the lens, causing loss of measurement accuracy. - Do not use this unit in an environment where electrical noise is generated. Doing so may result in unstable display or larger errors.
- Page 4 Overview SK-8950 is a non-contact type waterproof thermometer, which detects the infrared energy emitted from an object and converts it into a temperature reading. The product can measure the temperature of the surface instantly without touching the object. Features Waterproof/dustproof structure The unit is the property of IP54 (JIS C 0920), meaning that you can operate the unit with wet hands.

- Page 6 This label based on JIS C 6802 Radiation Safety Standards for Laser Product and Japan’s Consumer Product Safety A 2. Loading the Batteries When using the unit for the first time or replacing the batteries, install the batteries as described below.
- Page 7 Caution The replacement batteries must be new and of the same type. Mixed use of different types or new and old batteries could cause an explosion or leakage. Do not dispose of used batteries in a fire. Doing so could cause the batteries to explode, resulting in injuries or burns.
- Page 8 3-1 Measurement Spot Size The measurement spot size of this thermometer changes in accordance with the distance as shown below. Distance Diameter The diameter of the measuring spot shown above is defined on the basis of the area that receives 90% or more of the energy.
- Page 9 Note: The laser marker is designed to be used as a guideline. The unit accurately measures the temperature when the object to be measured is larger than the target area. For details, refer to the "Measurement target area". Note that the misalignment between the laser marker and the target area becomes larger with a smaller measurement distance as shown in the figure above.

Page 10: Setting The Emissivity
4-1 Setting the emissivity All objects emit infrared radiation corresponding to their surface temperature, but the emissivity value depends on the condition of the object’s surface. Measurement is more accurate when the emissivity of the object is properly set. Note that the emissivity cannot be changed while automatic measurement is being performed. To change the emissivity setting, cancel the automatic measurement. - Page 11 The minimum temperature value appears on the display (lower row). (2) The unit displays the minimum temperature value measured while in the manual or automatic measurement mode. 4-4 Temperature difference (dIF) display The unit displays the difference between the maximum and minimum temperature values measured while the measurement trigger is being pulled or in the automatic measurement mode.
- Page 12 4-7 Alarm lower limit value (LAL) setting Set the alarm lower limit value. If the measured value falls below the lower limit value, the alarm buzzer starts sounding. (Because the unit is waterproof and sealed, the buzzer sound may be hard to hear.) Note that the alarm lower limit value cannot be changed while automatic measurement is being performed.
