5.2 Changing Measurement Units (fc/lx)
ni bosing fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 HOLD funktsiyasi
ni bosing TUTING 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)
Nolinchi sozlashni amalga oshirish uchun:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- ni bosing KAL 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 Diapazonni tanlash
The device typically operates in auto-ranging mode. To manually select a range or cycle through available ranges, press the RANGE button. The display will indicate the active range. Press and hold the RANGE button to return to auto-ranging mode.
5.6 Min/Max Function (Power-Up Option)
The PCE-170 A supports Min/Max recording. To activate this feature, refer to the power-up options indicated on the device label (e.g., press and hold a specific button during power-on). This function records the minimum and maximum illuminance values detected during a measurement session.
6. Xizmat ko'rsatish
6.1 Tozalash
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the light sensor clean and free of dust or smudges, as this can affect measurement accuracy.
