The MS6612 supports both automatic and manual range switching.
- In auto-ranging mode, the meter automatically selects the best measurement range.
- -ро пахш кунед РАНГ 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 Функсияи нигоҳдории маълумот
Барои ях кардани хониши ҷорӣ дар экран:
- -ро пахш кунед ДОРЕД button. The "HOLD" indicator will appear on the display.
- -ро пахш кунед ДОРЕД button again to release the data hold and resume live measurement.
5.5 Maximum/Minimum Value Measurement
Ба view the maximum or minimum illuminance recorded during a measurement session:
- -ро пахш кунед МАКС/MIN button. The display will show the maximum recorded value.
- пахш кунед МАКС/MIN again to cycle to the minimum recorded value.
- пахш кунед МАКС/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.
- -ро пахш кунед ҚУЛЛА button to activate peak measurement. The "PEAK" indicator will appear.
- The display will show the highest illuminance detected since activating the function.
- пахш кунед ҚУЛЛА боз барои баромадан аз ин режим.
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.
- пахш кунед 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).
