4. Configuració

4.1 Instal·lació de la bateria

The AR850+ gauge requires three (3) 1.5V AAA batteries (not included). To install the batteries:

1. Localitzeu el compartiment de la bateria a la part posterior del dispositiu.
2. Feu lliscar la tapa del compartiment de la bateria cap avall per obrir-lo.
3. Introduïu tres piles AAA, assegurant-vos de la polaritat correcta (+/-) tal com s'indica a l'interior del compartiment.
4. Torneu a col·locar la tapa del compartiment de la bateria lliscant-la cap amunt fins que encaixi al seu lloc.

4.2 Connexió de la sonda

Connect the probes to the bottom of the gauge:

1. Identify the two probe ports at the bottom edge of the gauge.
2. Insert the connectors from the probes firmly into these ports. Ensure a secure connection.

5.2 Calibració

Before taking measurements, it is recommended to perform a zero adjustment using the included calibration block.

1. Assegureu-vos que la sonda estigui neta i lliure de residus.
2. Apply a small amount of coupling agent to the surface of the calibration block.
3. Place the probe firmly and flatly onto the calibration block.
4. The device will automatically perform a zero adjustment. Refer to the display for confirmation.

5.3 Prendre mesures

To measure the thickness of a material:

1. Ensure the surface of the material to be measured is clean and smooth. Remove any rust, paint, or loose particles.
2. Apply a small amount of coupling agent to the measurement point on the material surface. The coupling agent ensures proper transmission of ultrasonic waves.
3. Place the probe firmly and flatly onto the prepared surface. Ensure there are no air gaps between the probe and the material.
4. The thickness reading will appear on the LCD display.
5. If the reading is unstable or shows '----', reapply coupling agent or adjust the probe position.

5.4 Switching Units (mm/m/s)

To switch between millimeters (mm) for thickness readings and meters per second (m/s) for sound speed readings, press the UP or ABAIX arrow buttons on the front panel.

5.5 Emmagatzematge i recuperació de dades

The device can store up to 10 measurement results and 12 sound speed values. To store or recall data, use the Memòria button and navigation keys as per the on-screen prompts.

6. Manteniment

6.1 Neteja

Regular cleaning ensures optimal performance and longevity of your gauge:

• After each use, wipe the probe and the gauge's surface with a soft, dry cloth to remove any residual coupling agent or dirt.
• No utilitzeu productes de neteja abrasius ni dissolvents, ja que poden danyar el dispositiu.

6.2 Emmagatzematge

When not in use, store the AR850+ gauge in its aluminum carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.

6.3 Substitució de la bateria

When the low battery indication (3V +/- 0.2V) appears on the display, replace all three AAA batteries promptly to ensure accurate readings and prevent device malfunction.
