- ກົດ ພະລັງງານ ປຸ່ມເພື່ອເປີດເຄື່ອງວັດ.
- ກົດ ພະລັງງານ ກົດປຸ່ມອີກຄັ້ງເພື່ອປິດມິເຕີ.
- 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 ການວັດແທກພື້ນຖານ
- ເປີດແມັດ.
- 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.
- ກົດ ຫາຍາກ 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 ຟັງຊັນການຖືຂໍ້ມູນ
ເພື່ອຢຸດການອ່ານປັດຈຸບັນຢູ່ໜ້າຈໍ:
- ກົດ ຖື button. The "HOLD" indicator will appear on the display.
- ກົດ ຖື button again to release the data hold and resume live measurement.
5.5 Maximum/Minimum Value Measurement
ເຖິງ view the maximum or minimum illuminance recorded during a measurement session:
- ກົດ MAX/MIN button. The display will show the maximum recorded value.
- ກົດ MAX/MIN again to cycle to the minimum recorded value.
- ກົດ 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.
- ກົດ ສູງສຸດ button to activate peak measurement. The "PEAK" indicator will appear.
- The display will show the highest illuminance detected since activating the function.
- ກົດ ສູງສຸດ ອີກຄັ້ງເພື່ອອອກຈາກໂໝດນີ້.
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.
- ກົດ 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).
- ກົດ 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).
- ກົດ ໜ່ວຍ button to toggle between Lux and Fc units.
- The selected unit will be indicated on the LCD.
- ການແປງ: 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.
