Jekk jogħġbok aqra dan il-manwal bir-reqqa qabel ma tħaddem l-apparat u żommu għal referenza futura.
2. Informazzjoni dwar is-Sigurtà
Observe the following safety precautions to prevent injury and avoid damage to the device:
- Tesponix l-apparat għal temperaturi estremi, umdità, jew dawl tax-xemx dirett.
- Evita vibrazzjonijiet jew impatti qawwija.
- Tippruvax tiftaħ jew timmodifika l-apparat. Irreferi kull servizz lil persunal kwalifikat.
- Keep the light sensor clean and free from obstructions to ensure accurate readings.
- Neħħi l-batterija jekk l-apparat ma jkunx se jintuża għal perjodu twil ta' żmien biex tevita t-tnixxija.
- Armi l-batteriji u l-apparat skont ir-regolamenti lokali.
3. Prodott Aktarview
The PCE-170 A Light Meter consists of a main unit with a display and control buttons, and an integrated light sensor.

3.1 Komponenti
- Sensor tad-Dawl: Located at the top of the device, protected by a white dome. This silicon photodiode measures incident light.
- Display LCD: A 5-digit display showing measurement values, units (lux/fc), and function indicators (e.g., AUTO RANGE, HOLD, MIN, MAX).
- Buttuna tal-Enerġija (Mixgħula/Mitfija): Ixgħel jew jitfi l-apparat.
- Buttuna CAL: Used for zero adjustment.
- Buttuna ŻOMM: Jiffriża l-qari attwali fuq id-displej.
- fc/lx Button: Toggles between foot-candle (fc) and lux (lx) measurement units.
- Buttuna firxa: Manually selects measurement ranges or activates auto-ranging.
- Kompartiment tal-batterija: Located at the rear, houses the 9V battery.

4. Setup
4.1 Installazzjoni tal-batterija
- Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-apparat.
- Slide the cover open or unscrew it, depending on the model.
- Daħħal batterija waħda ta' 9V, waqt li tosserva l-polarità korretta (+/-).
- Ibdel l-għatu tal-kompartiment tal-batterija b'mod sikur.

4.2 Tixgħel Inizjali
Agħfas il- Qawwa button to turn on the device. The display will illuminate and show a reading. If the battery symbol appears, replace the battery.
5. Istruzzjonijiet Operattivi
5.1 Teħid ta 'Kejl
- Ixgħel l-apparat billi tuża l- Qawwa buttuna.
- 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)
Agħfas il- fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 Funzjoni HOLD
Agħfas il- ŻOMM 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)
Biex twettaq aġġustament żero:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- Agħfas il- CAL buttuna. Id-displej għandu juri "0.00" jew valur qrib ħafna ta' żero.
- Jekk id-displej ma jurix żero, irrepeti l-proċess.
5.5 Għażla tal-Medda
The device typically operates in auto-ranging mode. To manually select a range or cycle through available ranges, press the GANJA button. The display will indicate the active range. Press and hold the GANJA 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. Manutenzjoni
6.1 Tindif
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 Ħażna
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 Issolvi l-problemi
| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| L-apparat ma jixgħelx. | Batterija mejta jew installata ħażin. | Iċċekkja l-polarità tal-batterija jew ibdelha b'batterija ġdida ta' 9V. |
| Id-displej juri "OL" (Tagħbija żejda). | Light intensity exceeds the current measurement range. | Switch to a higher measurement range using the GANJA button, or move to a less intensely lit area. |
| Qari mhux preċiż. | 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. |
| Id-displej huwa vojt jew jitteptep. | Batterija baxxa. | Ibdel il-batterija ta '9V. |
