- LCD zaslon: A 5-digit display showing measurement values, units (lux/fc), and function indicators (e.g., AUTO RANGE, HOLD, MIN, MAX).
- Gumb za vklop (vklop/izklop): Vklopi ali izklopi napravo.
- Gumb CAL: Used for zero adjustment.
- Gumb HOLD: Zamrzne trenutno odčitavanje na zaslonu.
- fc/lx Button: Toggles between foot-candle (fc) and lux (lx) measurement units.
- Gumb RANGE: Manually selects measurement ranges or activates auto-ranging.
- Predal za baterije: Located at the rear, houses the 9V battery.

4.2 Začetni vklop
Pritisnite Moč button to turn on the device. The display will illuminate and show a reading. If the battery symbol appears, replace the battery.
5. Navodila za uporabo
5.1 Merjenje
- Vklopite napravo z uporabo Moč gumb.
- Prepričajte se, da je svetlobni senzor čist in neoviran.
- 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)
Pritisnite fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 Funkcija ZADRŽI
Pritisnite PRIDRŽI gumb za zamrznitev trenutnega odčitka na zaslonu. Ponovno ga pritisnite, da sprostite zadržanje in nadaljujete z meritvami v živo.
5.4 Zero Adjustment (CAL)
Za izvedbo nastavitve ničle:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- Pritisnite KAL button. The display should show "0.00" or a value very close to zero.
- Če zaslon ne prikazuje ničle, postopek ponovite.
5.5 Izbira območja
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. Vzdrževanje
6.1 Čiščenje
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 Shranjevanje

7. Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Naprava se ne vklopi. | Prazna ali nepravilno nameščena baterija. | Preverite polarnost baterije ali jo zamenjajte z novo 9V baterijo. |
| Na zaslonu se prikaže "OL" (preobremenitev). | Light intensity exceeds the current measurement range. | Switch to a higher measurement range using the RANGE button, or move to a less intensely lit area. |
| Netočni odčitki. | Dirty sensor, incorrect zero adjustment, or sensor not facing light source correctly. | Clean the sensor, perform zero adjustment in darkness, and ensure the sensor is properly oriented. |
| Zaslon je prazen ali utripa. | Nizka baterija. | Zamenjajte 9V baterijo. |
