Safety

International Safety Symbols
This symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information’s

Warning

• Do not directly or indirectly point the laser at the eyes of a person or an animal  Inspect for damage or for any shortage of parts or accessories before use
• Replace the  batteries immediately after the battery indicator flashes o Do not use the thermometer near explosive gases, steam, or dust
• Note that an object with high reflectivity will normally cause the measured temperature value to read much lower than the actual temperature
• Use the device only as described in this User Guide

Cautions

• To avoid thermometer damage, please avoid the following hazards:
  EMF from welding equipment or electro‐ induction heaters o Static electricity

• Thermal shock caused by large or abrupt environmental temperature changes; wait 30 minutes to allow the thermometer to stabilize to new environmental conditions

• Do not use this device in excessively high temperature environments

Distance & Spot Size

• As the distance(D) from the object increases, the spot size (S) of the area measured by the unit becomes larger.
• The relationship between distance and spot size for each unit is listed below.
• The focal point for each unit is 254mm (10”).
• The spot sizes indicate 90% encircled energy.

Operation

NOTES:

1. In HOLD MODE, Use the MODE Button to change MAX/MIN/DIF/AVG.
2. In Measurement Mode, if the TYPE-K thermocouple is connected, the Type-K data will displays in the lower left quarter automatically, during this this time, it cannot display EMS.
3. To set values for the High Alarm (HAL), Low Alarm (LAL) and Emissivity (EMS), press and hold the MODE Button until the appropriate code appears in the display, press the Up and Down Buttons to adjust the desired values.
4. You can turn ON/OFF the Backlight/Laser by pressing Laser/Backlight Button at any state.

MODE Button Function

• Press the MODE Button also allows you to access the set state, Emissivity (EMS), °C/°F, HAL adjustment, LOW adjustment, Each time you press set you advance through the mode cycle.
• The diagram shows the sequence of functions in the mode cycle.

EMS Adjustment

• The Emissivity (EMS) digitally adjustable from 0.10 to 1.0.

Changing Units (°C/°F)

• Pressing Up/Down Button to change the temperature unit (°C or °F).

Alarms ON/OFF (High and Low)

• Press the Laser/Backlight Button to turn ON/OFF
• Press the measurement trigger to confirm the High (Low) alarm mode Hal (Low) adjustment.
• The High (Low) alarm adjustable form -50 to 1000°C (-58 to 1832°F)

TRIG

• The function of TRIG means that when the TRIG is turn on ,press and hold the trigger for more than 10 minutes ,the device will turn off.

MAX MIN DIF AVG Display
MAX MIN DIF AVG indicate the MAX MIN DIF AVG record that displays between the pressing and releasing the “ON/OFF” Button each time.
MAX=Maximum; Maximum value of measurement. MIN=Minimum; Minimum value of measurement. DIF=Difference; Difference value of measurement.
AVG=Average; Average value of measurement.

Measurement Operation

• Hold the meter by its handle grip and point it toward the surface to be measured.
• Pull and hold the Trigger to turn the meter on and begin testing, the display will light if the battery is good, replace the battery if the display does not light.
• The meter will automatically power down after approximately 8 seconds after the trigger is released.

**NOTES:

• Holding the meter by its handle, point the IR Sensor toward the object whose temperature is to be measured.
• The meter automatically compensates for temperature deviations from ambient temperature.
• Keep in mind that it will take up to 30 minutes to adjust to wide ambient temperatures are to be measured followed by high temperature measurements, some time  (several minutes) is required after the low (and before the high) temperature measurements are made, this is a result of the cooling process, which must take place for the IR sensor.

Battery Replacement

• If the battery power is not sufficient, LCD will display ” Replace with a new 9V battery.
• Open the battery cover, then take out the battery from instrument and replace with new battery and place the battery cover back.

**Notes
How it Works

• Infrared thermometers measure the surface temperature of an object.
• The unit’s optics sense emitted, reflected and transmitted energy, which is collected and focused onto a detector.
• The unit’s electronics translate the information into a temperature reading, which is display on the unit.
• In units with a laser, the laser is used for aiming purposes only.

Field of View

• Make sure that the target is larger than the unit’s spot size.
• The smaller the target, the closer you should be to it.
• When accuracy is critical, make sure the target is at least twice as large as the spot size.

Distance & Spot Size
As the distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger.
Locating a Hot Spot
To find a hot spot aim the thermometer outside the area of interest, then scan across with an up and down motion until you locate hot spot.

Reminders

• Not recommended for use in measuring shiny or polished metal surfaces (stainless steel, aluminum, etc.), see Emissivity.
• The unit cannot 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 obstructing the unit’s optics.

Emissivity

• Emissivity is a term used to describe the energy-emitting characteristics of materials.
• Most (90% of typical applications) organic materials and painted or oxidized surfaces have an emissivity of 0.95 (Pre-set in the unit).
• Inaccurate readings will result from measuring shiny or polished metal surfaces.

Maintenance

• Repairs or service are not covered in this manual and should only be carried out by qualified trained technician.
• Periodically, wipe the body with a dry cloth.
• Do not use abrasives or solvents on this instrument.
• For service, use only manufacturer’s specified parts.
