1 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 which 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.

2 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 no to let the beam on a reflective surface strike your eye.

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

• It is prohibited to operated 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 inad-

equate conditions (e.g. if it is humid).

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

• Repairs must be realised solely by an authorised service work- shop.

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”).

Page 9

4 How it works

• Infrared

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.

Page 10

• Reminders

- Not recommended for use in measuring shiny or polished metal surfaces (stainless steel, aluminum, etc.). See Emis-

sivity.

- 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 (preset in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cove 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 additional error of emissivity other than 0.95. In this purpose, enter correct value of measured substance emissivity.

5 Measurement operation

• Hold the meter by it’s handle grip and point it toward the sur- face 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 sta-

tus, press the ①①①① button to turn on/off the laser and turn on/off backlight.

• The meter will automatically power down after approximately 7 seconds after the trigger is released (unless the unit is locked on).

Page 12

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 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.
