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 accura-
cy while the backlight LCD and handy push-buttons combine for
convenient, ergonomic operation.
The Non-contact Infrared Thermometers can be used to meas-
ure the temperature of objects’ surface that is improper to be meas-
ured 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 pre-
sent manual and observe the safety regulations and recom-
mendations 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 recom-
mendations:
•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”).

4 How it works
•Infrared
Infrared thermometers measure the surface temperature of an
object. The unit’s optics sense emitted, reflected, and trans-
mitted energy, which is collected and focused onto a detector.
The unit’s electronics translate the information into a tempera-
ture 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 in-
terest, 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 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 measure-
ment 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. 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 meas-
ured substance emissivity.
