1. Set the temperature values:

C:36.8 Below alarm 25.0 H 46.8 H 26.2

C:36.8 Above alarm < 40.0 > H 46.8 H 26.2

13.2 Parameters

C:28.8 Parameters 42.7 08.50 27.2

■ Set parameters to enhance the accuracy of temperature measurements.
■ Each parameter addresses a variable that can affect the precision of the thermal readings.

13.2.1 Ambient temperature

C:36.8 H 46.8 Ambient temperature < 25.0 >

■ Deviations from the default temperature setting can affect the accuracy of readings.

Adjust the settings to match the ambient temperature.

13.2.2 Reflection temperature

Objects reflect infrared energy coming from surrounding objects. Reflected energy is added to the energy of the object itself, potentially causing measurement errors. Results are more likely to be affected with objects that have low emissivity.

In most applications (especially objects with high emissivity), the reflected temperature will reach an equilibrium with the ambient temperature. This has a minimal effect on temperature measurements.

In environments with higher temperature sources close to the object being measured, it is necessary to compensate for reflected energy by setting a temperature value for the environmental heat source.

C:36.8 H 46.8 Reflection temperature < 25.0 >

1. Set the emissivity to 1.00. See section: Emissivity [▶ 55].

2. Point the lens 180^ away from object to be measured.

3. Take a measurement and then press the trigger to hold (freeze) the image.

4. Determine the average value of the image.

→ Average value: take multiple readings and divide by number of readings taken.

1. Input the value via the onscreen settings.

→ This setting will be factored in to create a temperature reading adjustment to account for reflected energy.

13.2.3 Atmospheric humidity

C:36.8 H 46.8 Atmospheric Humidity < 60% >

■ Water droplets in the air can absorb infrared rays, and affect the accuracy of readings.
- Adjust the settings to match the humidity levels.

13.2.4 Infrared compensation

C:36.8 Infrared compensation < 0.0 > H 46.8

■ Various factors can affect measurement accuracy (e.g., accuracy drift over time).
In automatic mode, set a compensatory value if there is a known discrepancy between the measured temperature and the actual object temperature.

13.2.5 Distance

C:36.8 H 46.8 distance 2.0

Infrared energy reduces as the distance from the measured object increases.
Adjust for this by entering the distance to the measured object.

13.2.6 Emissivity

C:36.8 H 46.8 Emissivity < 0.95 > ε↑ 28.7

■ Emissivity settings can be adjusted manually, and in smaller increments.
For further information on emissivity see: Emissivity and accuracy [▶ 48]

19 About the lens (Item No.: 2890410)

Focal length FOV (horizontal) FOV (vertical) IFOV*
9 mm 41.5° 31.1°	1.89 mrad

FOV (Field of view)

This is the largest area the imager can capture at a set distance.

IFOV (Instantaneous field of view)

This is the smallest object that the temperature can be measured accurately by the thermal imager.
Unit: rad
■ Formula: IFOV = (pixel size) / (lens focal length).
D:S theoretical (=1 / IFOV theoretical) is the calculated spot size based on the pixel size of the detector array and lens focal length.

Example

Lens = 9 mm, pixel size = 17 μm, FOV (horizontal) = 41.5°, FOV (vertical) = 31.1°, IFOV = 17 μm / 9 mm = 1.89 mrad.
D:S theoretical (= 1 / IFOV theoretical) = 529:1.

Spot Size = 100.00 cm x 100.00 cm (based on IFOV theoretical) 384m 288m 41.5° 31.1° 529m

D:S measure (= 1 / IFOV measure) is the spot size needed to provide an accurate temperature measurement.
D:S measure is typically 2 to 3 times smaller than D:S theoretical. This means the temperature measurement area of the target needs to be 2 to 3 times larger than that determined by the calculated theoretical D:S.
