3. Emission factor: The physical quantity known as the emission factor

describes to what extent the infrared heat radiation that is emitted from an

object is determined by Its own temperature. Accordingly, a value of 1 tells

us that the infrared heat radiation from the object is based only on its own

temperature. A value of less than 1 means that the radiation emitted from

the object is not only deter mined by its own temperature but also by

reflections from neighboring bodies or due to the transmission, i.e. the

diathermancy, of the object. The emission factor thus has an effect on the

result of the measurement. The Infra-Red Thermometer works with an

emission factor of 0.95, i.e. the measuring unit assumes that the object

being monitored has a factor of 0.95. If this is not the case, there will be

inaccuracies in the measurement (see Section 2.5 “Measuring

inaccuracies").

2. Operation

2.1. Display and operator controls

All the functions of the measuring unit are

controlled and monitored using the

operating button 7 and the back-lit display.

1 Temperature display - currently

measured value

2 Hold indicator

3 Temperature display - minimum value

4 Temperature display - maximum value

5 Battery symbol - (low battery indicator)

6 Temperature units - °C or °F

7 Operating button

8 Lens

2.2. Making a measurement

The unit is switched on by pressing the operating button. The display will

show horizontal bars until the first measurement is available. The current

temperature will then be displayed in the upper main part of the display.

The button must be pressed for the duration of the measurement, where by

the display of the measured value will be continuously updated. The lens

must be focussed on the object while the measurement is being made. At

the same time, the object being measured must be larger than the area

monitored by the Infra-Red Thermometer (see 2.5. “Measuring

inaccuracies”). The measurement will be finished by releasing the button.

The “Hold” indication signals that measuring has stopped. The last

measurement will be shown in the upper main part of the display. The

display back light will go out 8 seconds after the button has been released.

The unit will switch itself off automatically 30 seconds after the last

measurement. It will be necessary to replace the batteries as soon as the

battery symbol appears in the display.

2.3. Minimum and maximum temperature indication

The minimum and maximum value memories are cleared at the start of a

measurement by pressing the operating button. The temperature will be

measured and the minimum and maximum temperatures will be determined

for as long as the button is pressed. The minimum temperature is shown in

the lower left hand part of the display and the maximum temperature can be

seen in the lower right hand part. These values each apply to the current

measuring cycle and are cleared as soon as the button is pressed again.

2.4. Changeover °C/°F

The units for the temperature display can be switched between degrees

Centigrade (°C) and degrees Fahrenheit (°F) by pressing the button briefly

twice (double click).

2.5. Back-light

The LCD back-light is constantly switched ON when the Operating button is

pressed. When releasing the Operating button, the back-light will be ON for

approximately 8 seconds before automatically switching OFF.

1. General

1.1. Equipment supplied

• Infra-Red Thermometer base unit

• 4 button cells (already fitted in unit)

1.2. Additional note for newly purchased thermometer

The newly purchased thermometer comes with 4 x LR44 alkaline cells already

inserted inside the battery compartment. For the first time using the

thermometer, gently remove the insulated piece by slowly pulling it out from the

battery compartment.

Test the thermometer by pressing the operating button, the LCD display and

back light will light up briefly. If it is not the case, remove the cells. Wait for 30

seconds, and reinsert the cells again. Make sure the cells are at the positive (+)

pole up into the battery compartment.

Your thermometer is now operational!

1.3. Description of measuring principle

When making a temperature measurement, the surface radiation of the object to

be measured is evaluated using the principle of radiation thermometry. This is a

purely passive process, i.e. no radiation is transmitted, but instead, use is only

made of the natural electromagnetic radiation energy (heat radiation) that every

body above a temperature of absolute zero (-273°C) has. The temperature can

be determined very accurately from this radiation energy if the emission factor of

the object being measured is known.

1.4. Technical information

1.4.1.Technical data

The important technical data are summarized in the adjacent table.

1.4.2.Notes on technical data

1. Accuracy: The larger of the two values given is applicable in each case.

2. Distance to measuring spot size: The parameter D:S characterizes the size of

the measuring spot in proportion to the distance between the object to be

measured and the Infra-Red Thermometer. For example, with a ratio of 6:1 and a

distance of 60 cm, the monitoring area will have a diameter of 10 cm.

Range -20°C to 300°C

Resolution 0.1°C

Accuracy ±2% or ±2°C

Unit °C or °F

Distance to measuring spot size D:S 6:1

2.6. Measurement inaccuracies

The following points should be observed in order to avoid measurement errors:

1. It must be ensured that the object to be measured completely fills the Infra-

Red Thermometer monitoring area. Errors can occur when measuring small

objects, as the non-contact thermometer also monitors the temperature of the

surroundings as well as the object to be measured. The temperature of the

whole of the monitoring area is determined.

2. The principle of measurement requires the ambient temperature to be

determined. This takes place at 1-minute intervals or each time the unit is

switched on. Changes in the ambient temperature, which can occur when the

user holds the unit in his hand, are not monitored within this time period and

therefore neither of them are taken into account when determining the

indicated temperature. A gradual warming of the unit (the lens) between

ambient temperature measurements can, for example, lead to the indicated

temperature slowly falling.

3. If the emission factor for the object does not correspond to the preset value of

0.95, the temperature will not be calculated correctly. Most surfaces have an

emission factor in the range of 0.8 to 0.99. In general, the darker and more

matt the surface is, the larger its emission factor. If the factor is greater than

0.95, the temperature indicated will be greater than the actual temperature of

the object being measured. If the factor is less than 0.95, the temperature

indicated will be less than the surface temperature.

Polished metals have a very low emission factor and are therefore not

suitable for measuring with a non-contact thermometer. On the other hand,

affixing adhesive tape to or painting the surface will increase the emission

factor and reduce the inaccuracy of the measurement.

4. It is not possible to take measurements through transparent materials (glass,

plexiglass etc.).

5. It is not possible to measure air temperatures.

6. Measurement errors can occur due to air contaminated with dust, steam,

smoke, etc.

2.7. Fault finding

• Display shows -.-

• The operating button has not been pressed for long enough. This must be

pressed for at least the duration of one measurement, i.e. for at least 1.5

seconds.

• Display shows Err.1

• The ambient temperature is outside the permitted range.

• Display shows 1.

• The measured value is outside the permitted range.

• Battery symbol illuminates.

The batteries are flat. See 3.1 Changing the batteries.

3. Maintenance

3.1. Changing the batteries

If the battery symbol appears in the display, the batteries must be changed. The

four button cells are accessible after opening the battery compartment at the

rear of the unit. The used batteries must be removed from the battery holders

and replaced by new button cells of the same type. Only LR44 type batteries

may be used. Care must be taken to ensure that the polarity is correct when

inserting. The plus terminal of all four batteries should point upwards. The

batteries must be checked to see that they are properly seated before closing

the battery compartment.

Note: Used batteries should not be disposed of in the household

waste. Old batteries and batteries that no longer work can be

handed in to the local collection point free of charge.

3.2. Cleaning

Clean the unit using only a dry cloth. If the unit is very dirty, the cloth may be

slightly dampened. Do not use cleaners containing solvents. Make sure that no

moisture enters the interior of the unit.

When cleaning the lens, loose particles must be removed using

compressed air. Any remaining dirt can then be removed with a soft

brush or with a cotton-wool bud moistened with water. CAUTION!

Do not use cleaners containing solvents.

4. Fastening the lnfra-Red Thermometer

The carry necklace is supplied with the thermometer.

To fasten, simply insert the clip of the necklace into the buckle end

of the thermometer until it clicks into place.

To unfasten, simply press both sides of the clip and pull until it can

be removed from the buckle.
