4. Uppsetning
4.1 Uppsetning rafhlöðu
- Finndu rafhlöðulokið aftan á mælinum.
- Use a screwdriver (if necessary) to open the battery compartment.
- Insert one 9V (IEC 6LR61) battery, observing the correct polarity (+/-).
- Settu hlífina yfir rafhlöðuhólfið aftur og festu það.
Athugið: Vísir um lága rafhlöðu birtist á skjánum þegar þarf að skipta um rafhlöðu.
5. Notkunarleiðbeiningar
5.1 Kveikt/slökkt
- Ýttu á KRAFTUR hnappinn til að kveikja á mælinum.
- Ýttu á KRAFTUR button again to turn the meter off.
- 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 Grunnmælingar
- Kveiktu á mælinum.
- Point the light sensor towards the light source to be measured.
- 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.
- Ýttu á RANGE 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 Gagnahaldsaðgerð
Til að frysta núverandi mælingu á skjánum:
- Ýttu á HOLD button. The "HOLD" indicator will appear on the display.
- Ýttu á HOLD button again to release the data hold and resume live measurement.
5.5 Maximum/Minimum Value Measurement
Til view the maximum or minimum illuminance recorded during a measurement session:
- Ýttu á MAX/MIN button. The display will show the maximum recorded value.
- Ýttu á MAX/MIN again to cycle to the minimum recorded value.
- Ýttu á 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.
- Ýttu á Hámark button to activate peak measurement. The "PEAK" indicator will appear.
- The display will show the highest illuminance detected since activating the function.
- Ýttu á Hámark aftur til að hætta í þessari stillingu.
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.
- Ýttu á REL aftur til að hætta í hlutfallsmælingarham.
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).
- Ýttu á NÚLL 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).
- Ýttu á UNIT button to toggle between Lux and Fc units.
- The selected unit will be indicated on the LCD.
- Umbreyting: 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. Viðhald
6.1 Þrif
- Þurrkaðu af mælinumasing með mjúkum, damp klút. Ekki nota slípiefni eða leysiefni.
- Keep the light sensor clean and free from dust or smudges to ensure accurate readings. Use a soft, lint-free cloth.
6.2 Skipt um rafhlöðu
Replace the 9V battery when the low battery indicator appears on the display. Follow the steps in Section 4.1 for battery installation.
6.3 Geymsla
- If storing the meter for an extended period, remove the battery to prevent leakage and potential damage.
- Geymið mælinn á köldum, þurrum stað, fjarri beinu sólarljósi og miklum hita.
