 Introduction

Thank you for purchase of the IR Thermometer DIT-500. This is capable of non- contact (infrared) temperature measurements at the touch of a button. The built-in laser pointer increases target accuracy while the backlight LCD and handy push buttons combine for convenient, ergonomic operation. The Non- contact Infrared Thermometers can be used to measure the temperature  of objects’ surface that is improper to be  measured by traditional (contact) thermometer (such as moving object, the surface with electricity current or the objects which are uneasy to be touched.)
Proper use and care of this meter will provide years of reliable service.
In the present manual, we apply three kinds of warnings. These are texts in frames, which describe possible dangers both for the user and the meter itself. The messages starting from the word ‘WARNING:’ describe situations that imply a risk for life or health should the recommendations presented in the present manual not be observed. The word ‘ATTENTION!’ introduces a description of a situation where non-observance of the recommendations presented in the present manual may imply damage for the meter.  Indications of possible problems are preceded by the word ‘Attention:’.

WARNING:
Before using the instrument acquaint yourself with the present manual and observe the safety regulations and recommendations specified by the manufacturer.

Safety

In order to guarantee proper operation and correctness of the obtained results it is necessary to observe the following recommendations:

• Use extreme caution when the laser beam is turned on.

• Do not let the beam enter your eye, another person’s eye or the eye of an animal.

• Be careful not to let the beam on a reflective surface strike your eye.

• Do not allow the laser light beam to impinge on any gas which can explode.

• It is prohibited to operate the meter:
  If it is damaged and completely or partially out of order.
  If it has been stored for an excessive period of time in inadequate conditions (e.g. if it is humid).

• Before commencing a measurement make sure the correct measurement function has been selected.

• Repairs must be realized solely by an authorized service workshop.

3.4 Distance and 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 of unit is 914mm (36”).

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 and 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
  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 (preset in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the surface to be measured with masking tape or flat black paint. Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or painted surface. The DIT-500 can compensate for an additional error of emissivity other than 0.95. In this purpose, enter the correct value of measured substance emissivity.

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.
• Release the trigger and the HOLD display icon will appear on the LCD indicating that the reading is being held. In HOLD status, press the ① button to turn on/off the laser and turn on/off the backlight.
• The meter will automatically power down after approximately 7 seconds after the trigger is released (unless the unit is locked on).

Note: Measurement considerations
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 the 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.
