- ປຸ່ມເປີດ/ປິດ: ເປີດ ຫຼື ປິດອຸປະກອນ.
- ປຸ່ມ CAL: Used for zero adjustment.
- ປຸ່ມຖື: ຢຸດການອ່ານປັດຈຸບັນຢູ່ໃນຈໍສະແດງຜົນ.
- ປຸ່ມ fc/lx: Toggles between foot-candle (fc) and lux (lx) measurement units.
- ປຸ່ມ RANGE: Manually selects measurement ranges or activates auto-ranging.
- ຊ່ອງໃສ່ຫມໍ້ໄຟ: Located at the rear, houses the 9V battery.

4.2 ການເປີດເຄື່ອງເບື້ອງຕົ້ນ
ກົດ ພະລັງງານ button to turn on the device. The display will illuminate and show a reading. If the battery symbol appears, replace the battery.
5. ຄໍາແນະນໍາການດໍາເນີນງານ
5.1 ການວັດແທກ
- Turn on the device using the ພະລັງງານ ປຸ່ມ.
- Ensure the light sensor is clean and unobstructed.
- Position the light sensor at the location where illuminance is to be measured. Ensure the sensor is facing the light source directly for accurate readings.
- The current illuminance value will be displayed on the LCD.

5.2 Changing Measurement Units (fc/lx)
ກົດ fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 ຟັງຊັນຖື
ກົດ ຖື button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.
5.4 Zero Adjustment (CAL)
ເພື່ອດໍາເນີນການປັບສູນ:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- ກົດ CAL button. The display should show "0.00" or a value very close to zero.
- If the display does not show zero, repeat the process.
5.5 ການເລືອກໄລຍະ
The device typically operates in auto-ranging mode. To manually select a range or cycle through available ranges, press the ຫາຍາກ button. The display will indicate the active range. Press and hold the ຫາຍາກ button to return to auto-ranging mode.
