CME=0.95 09 57 S:19.1 27.4 Above alarm 18.2

12.2 Parameters

°CM E=0.95 09 57 S: 18.9 27.3 Parameters 18.2

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

12.2.1 Ambient temperature

°CM E=0.95 09 58 S:18.5 26.4 Ambient temperature

■ Deviations from the default temperature setting can affect the accuracy of readings.
- Adjust the settings to match the ambient temperature.

12.2.2 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.

°CM E=0.95 17 15 S:36.7 46.3 Reflection temperature < 25.0 >

1. Set the emissivity to 1.00. See section: Emissivity setting [▶ 43].
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.

12.2.3 Atmospheric humidity

°CM E=0.95 17 15 S:36.7 46.3 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.

12.2.4 Infrared compensation

°CM E=0.95 17 15 S:36.7 46.3 Infrared compensation < 0.0 >

12.2.5 Distance

°CM E=0.95 17 15 S:36.7 46.3 Distance 2 >

■ 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.

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

12.2.6 Emissivity

°CM E=0.95 17 15 S:36.7 46.3 Emissivity < 0.95 > ε↑

■ Emissivity settings can be adjusted manually, and in smaller increments.
For further information on emissivity see: Emissivity and accuracy [▶ 43].

12.3 Image modes

°CME=0.95 11:10 S:31.6 39.0 + Auto fusion 28.5

Image modes

20 Cleaning and care

20.1 Housing

Important:

• Do not use aggressive cleaning agents, rubbing alcohol or other chemical solutions. They damage the housing and can cause the product to malfunction.

• Do not immerse the product in water.
  – Risk of dirt / debris contaminating lens. Always use the included lens cap to cover the lens before cleaning the housing.

• Clean the product with a dry, fibre-free cloth.

20.2 Infrared lens

Important:

• The lens has an anti-reflective coating that can get damaged if not cleaned correctly.
• Do not use abrasive materials and/or chemicals to rub/clean the lens.
• Do not use the following abrasive materials as they may damage the anti-reflective coating (e.g., micro fiber cloths, kitchen towels, toilet paper, towels, shirt cuffs etc.

To reduce calibration errors and maximize accuracy, the lens should be free from dirt and debris.

1. Inspect the lens for dirt, dust, fingerprints etc.
2. Use a non-contact cleaning method first (e.g., manual pump air blower).
3. If further cleaning is required, use a fine tipped optical sensor cleaning swab.
   → Do not apply lens cleaning solution as this may damage / stain the lens.
4. Carefully wipe once across the lens (do not apply pressure).
   → To avoid scratches, wipe across the lens once and then discard the swab.
5. Repeat steps 2-4 as needed.

22 Disposal

22.1 Product

This symbol must appear on any electrical and electronic equipment placed on the EU market. This symbol indicates that this device should not be disposed of as unsorted municipal waste at the end of its service life.

Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose of it separately from unsorted municipal waste. Spent batteries and accumulators, which are not enclosed by the WEEE, as well as lamps that can be removed from the WEEE in a non-destructive manner, must be removed by end users from the WEEE in a non-destructive manner before it is handed over to a collection point.

Distributors of electrical and electronic equipment are legally obliged to provide free take-back of waste. Conrad provides the following return options free of charge (more details on our website):

in our Conrad offices
■ at the Conrad collection points
at the collection points of public waste management authorities or the collection points set up by manufacturers or distributors within the meaning of the ElektroG

End users are responsible for deleting personal data from the WEEE to be disposed of.

It should be noted that different obligations about the return or recycling of WEEE may apply in countries outside of Germany.

22.2 (Rechargeable) batteries

Remove batteries/rechargeable batteries, if any, and dispose of them separately from the product. According to the Battery Directive, end users are legally obliged to return all spent batteries/rechargeable batteries; they must not be disposed of in the normal household waste.

Batteries/rechargeable batteries containing hazardous substances are labelled with this symbol to indicate that disposal in household waste is forbidden. The abbreviations for heavy metals in batteries are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable) batteries, e.g. below the trash icon on the left).

Used (rechargeable) batteries can be returned to collection points in your municipality, our stores or wherever (rechargeable) batteries are sold. You thus fulfil your statutory obligations and contribute to environmental protection.

Batteries/rechargeable batteries that are disposed of should be protected against short circuit and their exposed terminals should be covered completely with insulating tape before disposal. Even empty batteries/rechargeable batteries can contain residual energy that may cause them to swell, burst, catch fire or explode in the event of a short circuit.
