NOTE

  • Alarm accuracy is ± 1°C (or ± 2 °F).
  • The low and high alarm values can be set only within the thermometer’s measurement range.
  • The high alarm value must be higher than the low alarm value.

Emissivity/ Setting Emissivity

Emissivity describes the energy-emitting characteristics of materials. Most (90% of typical applications) organic materials or non-shiny surfaces have an emissivity of 0.95 in the default setting. Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the surface to be measured with masking tape or flat paint. Allow the tape or paint to reach the same temperature as the surface it is covering. Then measure the temperature of the covered surface.

Substance Emissivity Substance Emissivity
Asphalt 0.90 – 0.98 Brick 0.93 – 0.96
Concrete 0.94 Cloth (black) 0.98
Cement 0.96 Human skin 0.98
Sand 0.90 Lather 0.75 – 0.80
Earth 0.92 – 0.96 Charcoal (powder) 0.96
Water 0.92 – 0.96 Lacquer 0.80 – 0.95
Ice 0.96 – 0.98 Lacquer (matt) 0.97
Snow 0.83 Rubber (black) 0.94
Glass 0.90 – 0.95 Plastic 0.85 – 0.95
Ceramic 0.90 – 0.94 Timber 0.90
Marble 0.94 Paper 0.70 – 0.94
Plaster 0.80 – 0.90 Textiles 0.90
Mortar 0.89 – 0.91

You can adjust the thermometer’s emissivity setting value so it can match the type of surface to be measured.

How to Set Emissivity

  1. When the thermometer is on, press and hold down the MODE button until the symbol flashes, then release the button.
  2. Press the button to decrease or the button to increase the emissivity setting value.
  3. When you finish emissivity setting, press and hold down the MODE button until the symbol stops flashing. The thermometer returns to normal operation.

Basic Measurement Procedure

  1. Hold the thermometer by its handle, and point it toward the surface to be measured.
  2. Pull and hold the trigger for at least 1 sec to turn on the thermometer and take measurement. Reading will be displayed on the main display.
    • NOTE: Each time the trigger is pulled, the pull must last at least 1 sec. The laser pointer (26, Figure F) is for reference only.
  3. During measurement, the symbol SCAN will flash on the main display, and when the trigger is released, the measurement stops and the symbol HOLD appears indicating that the last reading is locked.
  4. The thermometer will turn off automatically after about 50 seconds if the trigger or no buttons are pressed.

NOTE

  • Make sure the target surface is larger than the thermometer’s spot size. The smaller the target surface, the closer you should be to it (Refer to Field Of View section). When accuracy is critical, make sure the target is at least twice as large as the spot size.
  • To find a hot or cold spot, aim the thermometer outside the desired area 25 . Press and hold the trigger, slowly scan back and forth across the area until you locate the hot or cold spot. Refer to Figure C.

Measurement Considerations

  • Laser beam is mainly used to locate far objects. To save battery power, disable the laser function when measuring near objects.
  • The thermometer can not measure through transparent surfaces such as glass. It will measure the surface temperature of the glass instead.
  • Steam, dust, smoke, etc., can prevent accurate measurement by interfering with the energy emitted from the target.

MAINTENANCE

To Clean the Lens

  • Blow off loose dust and dirt with compressed air. Carefully wipe the surface with a moist cotton swab. Don’t use abrasive or solvent.

To Clean the Thermometer Housing

  • Use soap and water on a damp soft cloth. Don’t use abrasives or solvent.

NOTE: Do not immerse the thermometer in water, and do not let any liquid enter the case.

Specifications

  • Temperature Range: -50°C to 1350°C (-58°F to 2462°F)

Accuracy

  Range **Accuracy***
Celsius -50 °C to – 20 °C ± 5 °C
-20°C to 200 °C ± (1.5% of reading + 2 °C)
200 °C to 538 °C ± (2.0% of reading + 2 °C)
538 °C to 1350 °C ± (3.0% of reading + 5 °C)
Fahrenheit -58 °F to -4 °F ± 9°F
-4 °F to 392 °F ± (1.5% of reading + 3.6 °F)
392 °F to 1000 °F ± (2.0% of reading + 3.6 °F)
1000 °F to 2462 °F ± (3.0% of reading + 9 °F)

Accuracy specification assumes that the ambient operating temperature is 18 °C to 28 °C (64 °F – 82 °F) and the operating relative humidity is less than 80%.

Field of View

The farther the thermometer is from a target, the larger the target area will be, this is known as the distance to spot (D:S=20:1) ratio. For example: at a distance of 508 mm the spot will be 25.4 mm in diameter. The thermometer will display the average temperature across the target area.

  • DISTANCE: SPOT = 90% Energy
  • DISTANCE: SPOT ratio 20:1

_ NOTE: _For best accuracy make sure the object to be measured is larger then the thermometer’s spot size.

The thermometer has a visible red laser point 26 in the centre of eight outer dots. The red laser point shows the approximate location where the temperature is being measured. The outer dot pattern will become larger with distance. Figure E shows the laser point and outer dots near, Figure F shows the laser point and outer dots farther away.

NOTE: The laser point is only an approximate location, it is not an exact location.
