Additional Information

Operation

Operating the unit

  1. Open the battery door and insert a 9V battery properly.
  2. Pull the trigger to turn on the unit;
  3. Aim at the target surface and pull the trigger, then the temperature will be shown on the LCD. This unit is equipped with a laser, which is only used for aiming.
  1. Locating a Hot Spot

To find a hot spot, aim the thermometer outside of interest, then scan across with an up and down motion until you locate the hot spot. (Figure 1)

  1. Diagram description

(1) Trigger: When turn on the LCD display VERXX software version for 1 sec. And turn to display reading with SCAN icon. Release the trigger, display reading with HOLD icon. Built in auto power off in 30 sec.

(2) Laser/back light button: when the back light turns on, any operations will remain back light for 10 sec. LCD indicate on/off status.

(3) (6) key functions: press 3 key, LCD subdisplay blinks MAX-MIN-DIF-AVG-HAL-LAL-STO-EMS segment (only main display means normal measuring mode) press 4 key to enter.

  1. MAX: measuring maximum temperature
  2. MIN: measuring minimum temperature
  3. DIF: Basic on the reading before press 4 key, compute the difference of current
  4. AVG: measuring average temperature
  5. HAL: high temperature alarm–when selected HAL, press 5 keys to set high temperature alarm trigger and confirmed by pressing 4 key. When reading over the trigger, LCD display HI icon with BiBi audio sounds.
  6. LAL: low temperature alarm–when selected LAL, press 5 keys to set low temperature alarm trigger and confirmed by pressing 4 key. When reading over the trigger, LCD display LOW icon with BiBi audio sounds
  7. STO: data storage–when selected STO, lock & DATA & 1—indicator will be shown when press 4 key. After temperature read out press 6 key to store, then 2— memory unit will be shown. There are 12 groups memory unit available. To recall the stored data in normal measuring mode by pressing 6 key, remove all data by pressing 6 keys for 3 seconds.
  8. EMS: Emissivity setup– press 5 key for emissivity settings, press 4 key to save setup and back to normal status.
  9. Celsius/Fahrenheit switch: Please open the battery and push the slide switch for conversion.

Maintenance

  1. Lens Cleaning:
  2. Blow off loose particles using clean compressed air. Gently brush remaining debris away with a moist cotton swab. The swab may be moistened with water.
  3. Case cleaning: Clean the case with a damp sponge/cloth and mild soap.

Warning and Cautions

Warning:

To avoid the potential situation may cause harm or damage to people, please pay attention to the following items:

  1. Do not point laser directly at eye or indirectly off reflective surfaces.
  2. The unit cannot measure through transparent surfaces such as glass or plastic. It will measure the surface temperature of these materials instead.
  3. Steam, dust, smoke, or other particles can prevent accurate measurement by obstructing the unit’s optics.

Cautions:

The infrared thermometer should be protected for the following:

  1. EMF (electro-magnetic fields) from arc welders, induction heaters.
  2. Thermal shock (caused by large or abrupt ambient temperature changes allow 30 minutes for the unit to stabilize before use).
  3. Do not leave the unit on or near objects of high

Distance to Spot Size

  1. When taking the measurement, pay attention to the Distance to Spot Size. As the Distance (D) from the target surface increases, the spot size (S) of the area measured by the unit becomes larger. The Distance to Spot size of the unit is 50:1. This unit is equipped with a laser, which is used for aiming.
  2. Field of view:

Make sure the target is larger than the unit’s spot size. The smaller the target the closer measure distance. When accuracy is critical, make sure the target is at least twice as large as the spot size.

Emissivity

Emissivity: Most organic materials and painted or oxidized surfaces have an emissivity of 0.95 (present in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate for this, adjust the units emissivity reading or cover the surface to be measured with masking tape or flat black paint. Measure the tape or painted surface when the tape or painted surface reach the same temperature as the material underneath.

Material Emissivity Material Emissivity
Aluminum 0.30 Iron 0.70
Asbestos 0.95 Lead 0.50
Asphalt 0.95 Limestone 0.98
Basalt 0.70 Oil 0.94
Brass 0.50 Paint 0.93
Brick 0.90 Paper 0.95
Carbon 0.85 Plastic 0.95
Ceramic 0.95 Rubber 0.95
Concrete 0.95 Sand 0.90
