5. Дастурҳои истифодабарӣ
5.1 Андозагирӣ
- Turn on the device using the Қувва тугма.
- 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.
Расми 5: A user measuring light levels in an office environment with the PCE-170 A Light Meter.
5.2 Changing Measurement Units (fc/lx)
-ро пахш кунед fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 Функсияи нигоҳ доштан
-ро пахш кунед ДОРЕД 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)
Барои анҷом додани танзими сифр:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- -ро пахш кунед КАЛ 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 Интихоби диапазон
The device typically operates in auto-ranging mode. To manually select a range or cycle through available ranges, press the РАНГ button. The display will indicate the active range. Press and hold the РАНГ 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.
