5. Instrucțiuni de utilizare

5.1 Pornire/Oprire

• Apăsați tasta PUTERE pentru a porni contorul.
• Apăsați tasta PUTERE Apăsați din nou butonul pentru a opri contorul.
• The meter features an automatic power-off function, which will turn off the device if no keys are operated for more than 10 minutes.

5.2 Măsurare de bază

1. Porniți contorul.
2. Point the light sensor towards the light source to be measured.
3. The illuminance value will be displayed on the LCD. The meter automatically selects the appropriate range.

5.3 Range Switching (Auto/Manual)

The MS6612 supports both automatic and manual range switching.

• In auto-ranging mode, the meter automatically selects the best measurement range.
• Apăsați tasta GAMA button to switch between auto and manual ranging modes. In manual mode, you can cycle through available ranges.
• If the measured value exceeds the current range in manual mode, the LCD will display "OL" (Overload).

5.4 Funcția de păstrare a datelor

Pentru a îngheța citirea curentă pe afișaj:

• Apăsați tasta ȚINE button. The "HOLD" indicator will appear on the display.
• Apăsați tasta ȚINE button again to release the data hold and resume live measurement.

5.5 Maximum/Minimum Value Measurement

La view the maximum or minimum illuminance recorded during a measurement session:

• Apăsați tasta MAX/MIN button. The display will show the maximum recorded value.
• Presa MAX/MIN again to cycle to the minimum recorded value.
• Presa MAX/MIN a third time to exit this mode and return to live measurement.

5.6 Peak Value Measurement

This function captures the highest instantaneous illuminance value.

• Apăsați tasta VÂRF button to activate peak measurement. The "PEAK" indicator will appear.
• The display will show the highest illuminance detected since activating the function.
• Presa VÂRF din nou pentru a ieși din acest mod.

5.7 Relative Value Measurement

This function allows you to set a reference point and measure the difference from that point.

• In a stable light environment, press the REL button. The current reading becomes the reference, and the display will show "0".
• Subsequent measurements will show the difference (positive or negative) from this reference value.
• Presa REL again to exit relative measurement mode.

5.8 Zero Calibration Function

To ensure accuracy, especially in low light conditions, perform a zero calibration.

• Place the light sensor in a completely dark environment (e.g., cover it with an opaque cap).
• Apăsați tasta ZERO button. The display should read "0.00".
• This calibrates the meter to account for any residual sensor output in darkness.

5.9 Unit Conversion (Fc/Lux)

The meter can display measurements in Lux or Foot-Candles (Fc).

• Apăsați tasta UNITATE button to toggle between Lux and Fc units.
• The selected unit will be indicated on the LCD.
• Conversie: 1 Fc = 10.764 Lux; 1 Lux = 0.09290 Fc.

5.10 Touch Tone and Mute Function

The meter may emit a touch tone when buttons are pressed. This can be muted.

• Refer to the specific button on your device for muting the touch tone.

6. Întreținere

6.1 Curățare

• Ștergeți suprafața contoruluiasing cu un d moaleamp pânză. Nu utilizați agenți de curățare abrazivi sau solvenți.
