GENERAL

How often do I need to calibrate the HATO ONE?

The HATO ONE is a high-precision measurement device. It is also a very stable product which, when used with care, does not need to be calibrated yearly. However, to ensure the accuracy of measurements, we advise you to calibrate the device once a year.

How do I calibrate the HATO ONE?

My HATO ONE has fallen onto the floor. What do I do?

The HATO ONE is a high precision measurement device. It has fallen, or been dropped, is why, when it dropped on the floor, we advise you to calibrate the device. Watch the procedure here : https://www.uprtek.com/en/page/Calibrations/Service-Calibrations.html

How can I link my HATO ONE to my mobile phone?

  1. Activate the WiFi settings on your phone.
  2. Select HATO ONE in the WiFi functionality of your phone.
  3. Open the HATO ONE app and start measurements.

Can I link my HATO ONE to a tablet?

Yes, you can link your HATO ONE to your tablet.

  1. Activate the WiFi settings on your tablet.
  2. Select HATO ONE in the WiFi functionality of your tablet.
  3. Open the HATO ONE app and start measurements.

How can I download the software on my computer?

Visit this website and follow the instructions.

When I connect my HATO ONE to the PC it does not appear in my computer.

Go to options in the HATO ONE and change USB mode to Mass storage.

When I connect my HATO ONE to the PC it does not connect to the software.

Go to options in the HATO ONE and change USB mode to PC connection.

How often do I need to charge the battery?

The battery life will depend on the usage of the HATO ONE. Generally, you can use the HATO ONE for five hours when battery is fully charged.

MEASUREMENTS

How can I do captures from my mobile?

  1. Download the HATO ONE app
  2. Connect your phone to the HATO ONE (see FAQ; How can I link my HATO ONE to my mobile phone?)
  3. Open the HATO ONE app and press the wheel, measuring will start.

How can I switch from continuous measurements to single measurements?

In the Basic mode you will see an A or M at the top of the screen. If A is displayed, it means Auto mode, if M is displayed, it means Manual mode. You can switch between these two modes by tapping A or M.

Does the HATO ONE measure UV light?

The HATO ONE has been especially designed for measurements in poultry houses. Poultry have the ability to see UV lighting, so with the HATO ONE it is also possible to measure UV light to 350nm.

What are the most important values to measure?

There are several important elements of lighting:

  • The spectrum shows how much of each colour is available in the lamp. The HATO ONE allows the poultry spectrum to be placed over the measured one. This will enable you to see if it complies. The most important element is to provide a broad spectrum.
  • Flickering must always be prevented. Flickering can cause a high stress levels in poultry, which is why it is very important to measure this value.
  • It is also very important to measure (Galli-) lux levels. Each animal, house, farm and management system is different. By measuring the intensity values, you know how your animals respond at these levels. This allows you to adjust the levels and keep improving your performances.

Is it possible to obtain an overview with multiple measurements?

The HATO ONE has an analysis mode which makes it possible to measure your entire house easily. After the measurements, save the data and transfer to your PC. A report will be generated showing a correct overview of the lighting in your house, the average level of (Galli-) lux, uniformity, distribution etc.

ANALYSIS

How can I compare two light sources?

To compare two light sources, go to the compare app and select the sources you want to compare. In Basic mode you can compare all basic information such as lux, Gallilux, CCT, CRI etc. In Spectrum mode you can compare the spectrums of two different light sources.

How can I export the results to my PC as an Excel file?

You can export the results using the USB cable provided or by inserting the SD- card in your computer. For more information, consult the manual included.

How can I send the results to an email address?

There are two ways. When measuring using the app on your phone, you will see an envelope icon at the bottom. If you press this icon after measuring, a pop-up screen will appear. Use this screen to send the last measurements directly by e-mail.

Can I change the output in Excel to my country’s preferences?

You can change the output from “,” (comma) to “.” (dot).

Go to settings in any wanted mode and change the “decimal separator”.

How can I turn the poultry spectrum on/off in spectrum mode?

  1. Go to spectrum mode.
  2. Press the settings button.
  3. Scroll down to spectrum mode.
  4. Change your settings.

What is the right value of CCT for my poultry?

Every farm and farm management system differs. Please contact our specialised sales team to ask your specific question and we will give you tailor-made advice.

What is the right value of CRI?

There is no specific answer for this. The normal CRI value is an average of how well eight colour samples are presented compared with an ideal light source, whereby 100 is ideal. These eight colour samples, however, do not represent all important colours for several applications. For example, saturated colours like red are not within the standard CRI. Colour sample R9 is often used to compare how well the light source can produce saturated red.

A new standard for better colour comparison has been released, but it is not yet widely known. This standard compares 100 colour samples to achieve a much better representation of how well a light source is able to produce different colours.
CRI is only relevant for white light sources.

What is the correct lux and Gallilux level for my poultry?

Every farm and farm management system differs. Please contact our specialised sales team to ask your specific question and we will give you tailor-made advice.

What is the right spectrum for my birds?

Every farm and farm management system differs. Please contact our specialised sales team to ask your specific question and we will give you tailor-made advice.

What is the right value of flickering?

Poultry perceive light differently to humans. They perceive the flickering of light before humans do as well. However, even when flickering is not visible it still affects poultry, so a flicker-index of 0.0 is necessary to optimise animal health and welfare and ultimately the performance.

What is the right value of frequency?

There is no single answer here, as the perception of light change depends on different factors. For more information please read our blog about light flicker: click here

What does the CIE mode tell me?

The CIE diagram shows the colour coordinates of the light source in the CIE 1931 chart with two coordinates. Depending on the location, you can quickly see if the light source is  coloured or white and if it contains more red, more blue or other colours.

With two points in this chart, you can see a visual representation of all the colours that can be made when mixing both colours. With three colours (e.g. red, green and blue) you can mix more colours; basically any colour if the right colours are selected. Only the spectrum of the light source will always have just three narrow bands, which gives a poor representation of many colours.

It is not possible to assess the quality of white light using this chart. For coloured light: the closer the point is towards the edge of the chart, the purer the colour is.
The outer edge of the CIE1931 chart represents wavelengths of pure colour starting with blue and ending with red. The line of purples cannot be described as a single wavelength and is always a combination of different colours, similar to white light.
