3.1 Komponentët
- Sensori i dritës: Located at the top of the device, protected by a white dome. This silicon photodiode measures incident light.
- Ekrani LCD: A 5-digit display showing measurement values, units (lux/fc), and function indicators (e.g., AUTO RANGE, HOLD, MIN, MAX).
- Butoni i ndezjes (Ndezje/Fikim): Ndez ose fiket pajisjen.
- Butoni CAL: Used for zero adjustment.
- Butoni HOLD: Ngrin leximin aktual në ekran.
- fc/lx Button: Toggles between foot-candle (fc) and lux (lx) measurement units.
- Butoni RANGE: Manually selects measurement ranges or activates auto-ranging.
- Ndarja e baterisë: Located at the rear, houses the 9V battery.

4. Konfigurimi
4.1 Instalimi i baterisë
- Gjeni kapakun e ndarjes së baterisë në pjesën e pasme të pajisjes.
- Slide the cover open or unscrew it, depending on the model.
- Insert one 9V battery, observing the correct polarity (+/-).
- Zëvendësoni mirë kapakun e ndarjes së baterisë.

4.2 Ndezja fillestare
Shtypni Fuqia button to turn on the device. The display will illuminate and show a reading. If the battery symbol appears, replace the battery.
5. Udhëzimet e funksionimit
5.1 Marrja e një Matjeje
- Ndizni pajisjen duke përdorur Fuqia butonin.
- Sigurohuni që sensori i dritës të jetë i pastër dhe pa pengesa.
- 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)
Shtypni fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 Funksioni HOLD
Shtypni MBAJ 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)
Për të kryer një rregullim zero:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- Shtypni 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 Përzgjedhja e Diapazonit
The device typically operates in auto-ranging mode. To manually select a range or cycle through available ranges, press the FUSHA button. The display will indicate the active range. Press and hold the FUSHA 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. Mirëmbajtja
6.1 Pastrimi
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.
6.2 Ruajtja
When not in use, store the PCE-170 A Light Meter in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. Remove the battery if storing for extended periods.
7. Troubleshooting
