4. Konfigurazioa
4.1 Bateriaren instalazioa
The Mastech MS 6520B requires one 9V 6F22 battery for operation.
- Locate the battery compartment cover at the bottom of the handle.
- Gently slide or open the battery compartment cover.
- Connect a new 9V 6F22 battery to the battery connector, ensuring correct polarity.
- Jarri bateria konpartimentuan eta itxi estalkia ondo itxita.

5. Funtzionamendu-argibideak
5.1 Neurketa bat egitea
- Zuzendu infragorri sentsorea helburuko objekturantz.
- Sakatu eta eutsi neurketa-abiarazlea. Pantailak denbora errealeko tenperaturaren irakurketa erakutsiko du.
- Release the trigger to hold the last measured temperature on the display (Data Hold). The device will automatically power off after a period of inactivity to conserve battery.
5.2 Distantzia eta puntu arteko erlazioa (D:S)
The MS 6520B has a Distance to Spot Ratio (D:S) of 10:1. This means that at a distance of 10 units from the target, the measurement spot diameter will be 1 unit. For accurate readings, ensure the target area is larger than the measurement spot size.

5.3 Emisibotasuna
The device has a fixed emissivity setting of 0.95, which is suitable for most organic materials, painted surfaces, and many non-metallic objects. For highly reflective surfaces, readings may be less accurate.
5.4 Unitatearen hautaketa (°C/°F)
Sakatu °F/°C botoia Celsius eta Fahrenheit tenperatura unitateen artean txandakatzeko.
5.5 Atzeko argia
Sakatu Atzeko argia button to turn the display backlight on or off. This feature is useful in dimly lit environments.
5.6 Laser erakuslea
Sakatu Laserra button to activate or deactivate the laser pointer. The laser helps in precisely identifying the measurement target.
5.7 MAX/MIN/BATEZ BESTEKO Moduak
Sakatu M (Mode) button to cycle through different display modes while the trigger is held down:
- MAX: Displays the maximum temperature recorded during the current measurement session.
- MIN: Displays the minimum temperature recorded during the current measurement session.
- Batez bestekoa: Displays the average temperature recorded during the current measurement session.
6. Mantentzea
6.1 Garbiketa
- Garbitu gailua c.asing bigun batekin, damp oihal. Ez erabili garbitzaile edo disolbatzaile urratzailerik.
- Carefully clean the infrared lens with a soft cloth or cotton swab, slightly moistened with water or rubbing alcohol. Avoid scratching the lens.
6.2 Biltegiratzea
When not in use, store the thermometer in a dry, cool place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the battery to prevent leakage.
6.3 Bateria ordezkatzea
Replace the 9V battery when the low battery indicator appears on the display to ensure accurate readings and proper device function. Refer to Section 4.1 for battery installation instructions.
