4. Setup
4.1 Installazzjoni tal-batterija
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.
- Poġġi l-batterija fil-kompartiment u agħlaq l-għatu sew.

5. Istruzzjonijiet Operattivi
5.1 Teħid ta 'Kejl
- Point the infrared sensor towards the target object.
- Press and hold the measurement trigger. The display will show the real-time temperature reading.
- 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 Proporzjon tad-Distanza għall-Post (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 Emissività
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 Unit Selection (°C/°F)
Agħfas il- °F/°C button to toggle between Celsius and Fahrenheit temperature units.
5.5 Dawl ta 'wara
Agħfas il- Dawl ta' wara button to turn the display backlight on or off. This feature is useful in dimly lit environments.
5.6 Laser Pointer
Agħfas il- Laser button to activate or deactivate the laser pointer. The laser helps in precisely identifying the measurement target.
5.7 MAX/MIN/AVG Modes
Agħfas il- M (Mode) button to cycle through different display modes while the trigger is held down:
- MAX: Juri t-temperatura massima rreġistrata matul is-sessjoni tal-kejl attwali.
- MIN: Juri t-temperatura minima rreġistrata matul is-sessjoni tal-kejl attwali.
- AVG: Juri t-temperatura medja rreġistrata matul is-sessjoni tal-kejl attwali.
6. Manutenzjoni
6.1 Tindif
- Naddaf l-apparat casing b'artab, damp drapp. Tużax tindif jew solventi li joborxu.
- 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 Ħażna
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 Sostituzzjoni tal-batterija
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.
