Configuració
Instal·lació de la bateria:
The Protmex YT606 requires 4 AAA batteries (included). Follow these steps to install them:
- Localitzeu el compartiment de la bateria a la part posterior del dispositiu.
- Use the included screwdriver to open the battery compartment cover.
- Introduïu 4 piles AAA, assegurant-vos de la polaritat correcta (+/-) tal com s'indica a l'interior del compartiment.
- Substituïu la tapa del compartiment de la bateria i fixeu-la amb el cargol.
A low battery indicator will appear on the LCD screen when the batteries need to be replaced.
Instruccions de funcionament
Encès/apagat:
- Premeu el botó Botó d'encesa (1.) per engegar el dispositiu.
- Manteniu premut el botó Botó d'encesa (1.) for a few seconds to turn the device off.
Modes de mesura:
The YT606 offers four primary measurement modes:
- Temperatura ambient: Displays the current air temperature.
- Humitat relativa (RH): Mostra el percentatgetage of moisture in the air relative to the maximum amount it can hold at that temperature.
- Wet Bulb Temperature (WB): The temperature read by a thermometer covered in water-soaked cloth over which air is passed.
- Dew Point Temperature (DP): The temperature at which air becomes saturated with water vapor and dew begins to form.
To switch between Dew Point (DP) and Wet Bulb (WB) temperature displays, press the DP/WB button.

Figure 3: The four primary measurement modes of the YT606.
Nota: For stable and accurate readings, especially when moving the device between different environments, allow approximately 10 minutes for the sensor to adapt to the new conditions before taking measurements.
Unit Switching (°C/°F):
To switch the temperature unit between Celsius (°C) and Fahrenheit (°F), short-press the Botó °C/°F.

Funció de retenció de dades:
To hold the current measurement on the display, short-press the Botó H (Mantenir premut).. Press it again to release the data hold and resume live readings.

Figure 5: Using the Data Hold function.
MAX/MIN Value Display:
A view the maximum or minimum recorded values since the device was powered on or reset:
- Premeu el botó Botó MIN/MAX once to display the maximum (MAX) values.
- Premeu el botó Botó MIN/MAX again to display the minimum (MIN) values.
- Premeu el botó Botó MIN/MAX una tercera vegada per tornar a les lectures en directe.

Figure 6: Displaying Maximum and Minimum recorded values.
Data Logging (MEM/READ):
The YT606 can store up to 99 groups of data.
- To store the current reading, press the Botó MEM.
- Per recuperar les dades emmagatzemades, premeu la tecla Botó LLEGIR. Use the up/down arrow buttons to navigate through the stored data groups.
