4. 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 temperature changes. When low 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.

5. Non-Contact IR Measurement Operation

5.1. Power ON/OFF

1. Press the ON/HOLD key to take a reading. Read the measured temperature on the LCD.

2. The meter powers OFF automatically approximately 7 seconds after the ON/HOLD key is released.

5.2. Selecting Temperature units

Select the required temperature unit by opening the battery compartment (see point 7) and switchover the slide-switch, which is installed.

^ C is selected by manufacturer.

5.3. Data Hold

This meter automatically holds the last temperature reading on the LCD for 7 seconds after the ON/HOLD key is released.

No extra key presses are necessary to freeze the displayed reading.

5.4. Backlite LCD

Select backlite by first pressing the ON/HOLD key and then pressing the BACKLITE (5) key. Press the backlight key again to turn the backlight OFF.

5.5. Laser Pointer

1. To turn the laser pointer ON, press the LASER (4) key after pressing the ON/HOLD key
2. Press the Laser key again to turn OFF the laser.

Function

1. While measuring (triggered ON-key) use the UP and DOWN keys to adjust the Emissivity.
2. In the hold time (On-key not triggered), use the UP key to turn on or off and the DOWN key to turn on or off the backlight
3. To set values for the High Alarm (HAL), Low Alarm (LAL) and Emissivity (EMS), press the MODE button until the appropriate code appears in the display, press the UP and DOWN buttons to adjust the desired values.

MODE Button Function

Pressing the mode button with released ON-key also allows you to access the set

state, Emissivity(EMS), Lock on/off, HAL on/off, HAL adjustment, LOW on/off,

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) is digitally adjustable from 0.10 to 1.0. Press the UP and

DOWN-keys to raise or lower the EMS.

LOCK function

The lock mode is particularly useful for continuous monitoring of temperatures

without pressing the ON-key during the measurement.

Press the UP or DOWN key to turn on/off. Press the Measurement Trigger to

Confirm the locked measurement mode. The IR Thermometer will continuously

display the measured temperature until you press again the ON-key.

In lock mode, press the UP or DOWN keys to adjust the Emissivity.

HIGH (HAL) / LOW (LAL)- Alarm

Press the up button or down button to turn HAL/LAL on or off. Press the

Measurement Trigger to confirm the High/Low alarm mode.

After switching on or off the HAL/LAL, press the SET-key to switch to the

alarm-value setting.

Use the UP or DOWN-key to set the desired value for HAL or LAL.

When HAL or LAL is activated the backlight will flash in red color and A warning noise will sound.

This unit is equipped with a visual alarm.

If during a measurement, the measured temperature exceeds the preset "high alert" temperature, the backlight will flash with red LED. The same behavior shows the device when the measured temperature is lower than the preset "low alarm" temperature.

"High Alert" resp. "Low Alarm" to preset and must be enabled.

Emissivity: 0 - 1 variable

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, that the target is at least twice as large as the spot size.

7. Battery Replacement

A Bat Symbol in the display is the indication that the battery voltage has fallen into the critical region (6,5 to 7,5 V). Reliable readings can be obtained for several hours after the first appearance of the low battery indication.

Open the battery compartment (see picture below) and remove the battery, then install a new battery and replace the cover.

ATTENTION!

Batteries, which are used up dispose duly. Used up batteries are hazardous and must be given in the for this supposed collective container.

Notification about the Battery Regulation

The delivery of many devices includes batteries, which for example serve to operate the remote control. There also could be batteries or accumulators built into the device itself. In connection with the sale of these batteries or accumulators, we are obliged under the Battery Regulations to notify our customers of the following:

Please dispose of old batteries at a council collection point or return them to a local shop at no cost. The disposal in domestic refuse is strictly forbidden according to the Battery Regulations. You can return used batteries obtained from us at no charge at the address on the last side in this manual or by posting with sufficient stamps.

Contaminated batteries shall be marked with a symbol consisting of a crossed-out refuse bin and the chemical symbol (Cd, Hg or Pb) of the heavy metal which is responsible for the classification as pollutant:

1. "Cd" means cadmium.
2. "Hg" means mercury.
3. "Pb" stands for lead.

You can obtain further information about the Battery Regulations from the Bundesministerium für Umwelt, Naturschutz und

Reaktorsicherheit (Federal Ministry of Environment, Nature Conservation and Reactor Safety).

8. 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 displayed on the unit. In units with a laser, the laser is used for aiming purposes only.

8.1. 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.

8.2. Distance & Spot Size

As the distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger. See Fig. 2

8.3. 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

1. The unit cannot measure through transparent surfaces such as glass. It will measure the surface temperature of the glass instead.
2. Steam, dust, smoke, etc. can prevent accurate measurement by obstructing the unit's optics.

8.4 Emissivity

Most (90 % of typical applications) organic materials and painted or oxidised surfaces have an emissivity of 0,95. 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.
