Temperature Measurement

  1. Point the instrument to the surface of the object you want to measure and press the trigger.
  2. lt can display temperature, max temperature, min temperature, difference value, average value, max warning point, min warning point, external probe(not used in this product) measurement unit.
  3. The measuring result will stay on the screen for 7 sec after the trigger is loosen and it will be powered off if no operation is done.

Notice: Press the “MODE” button for 2 sec when the instrument is on to swift between ‘F and ‘C.

Dual laser spot

Dual laser distance is within 47.24 in (120 cm). And the temperature be measured is 3.93 in (10 cm) in diameter range in this distance.

Dual laser’s on and off

  1. Press and loose the trigger
  2. When “hold” is displayed, press the laser backlit button to power on and off the laser and to switch the backlit.
  3. Laser will be remained stored stage until it changes to another model.

Max Temperature Display

The max temperature is displayed in “MAX” after the temperature measurement is finished.

Backlight

  1. Press and loose trigger.
  2. Press the backlit button when the screen shows “HOLD” to switch backlit.
  3. When the backlit is on, it will light up the screen.
  4. Backlit will be remained stored stage until it changes to another model.

Press up and down button to adjust emissivity when it shows “HOLD”. The emissivity of this instrument is between 0.1-1.0.

Remark: backlit will consume the power of battery. Turn it off when you need not.

MODE menu operation

  1. lt can enter max value, min value, average value, max alarm point, min alarm point, external probe(not be used).
  2. Press and loose the trigger when it shows “HOLD”. Press the “MODE” to enter the next program.

Max data

Only shows the max data when measuring

Min data

Only shows the min data when measuring

Difference data

Shows the difference between the first and subsequent data.

Average data

Shows the average between the first and subsequent data.

HAL

To set the max alarm temperature, press the up and down menu.

LAL

To set the min alarm temperature, press the up and down menu.

Alarm when temperature is too high or too low

This product can alarm when the temperature is too high or too low.

It can release voice to remind users.

You can set the alarm temperature through the “MODE” menu. It can be remain the setting when it is power on until the setting is cancelled.

Temperature Unit

F or C can be set by the temperature unit switch menu, press the MODE menu for 2 sec.

Over Range Alarm Function

If the temperature is beyond the instrument can measured, it will shows “—-“on the screen.

Battery Replacement

When it shows low power signals “LOG”, please replace battery (QV). The battery is under the trigger.

Do not discard the used battery into the dustbin.

Attention

The object to be measured must larger than the vision field of the instrument. Keep the object surface clean and free from frost, oil and dirt etc. when measuring. If the object to be measured is easy to reflect, cover it by adhesive tape or black paint before measuring. The object to be measured is transparent such as glass may not have an accurate result. Steam, dust, smog etc can influence the measuring result. This instrument can adjust the environment temperature deviation. But if the deviation is huge it may cost about 30 minutes to adjust. To find a hot spot, please point the object from top to bottom and from left to right until you find it out.

Distance Co-efficient Ratio

The distance coefficient ratio of this product is 12:1. For example, if the object to be measured is 28.34 in (72 cm) far from the instrument, then the diameter of the object must bigger the 2.36 in (6 cm). It can measure proper distance but can be influenced by other light source.

Emissivity and Infrared Temperature Measurement Principle

Infrared thermometer is an instrument that measures the surface temperature. lt goes through infrared emission, reflection and is then converted into energy. Thermometer converts the electrical signals into temperature reading displayed on the LCD. The infrared energy object can release is in direct proportion with its temperature and emissive power. This is called emissivity and is related to the material and gloss of the object. The emissivity value ranges from 0.1 to 1.0. The emissivity of most organic material and paint and the surface be oxidized is 0.95. If there is any problem, please set the emissivity to be 0.95.
