3.1 Komponenter
- Lyssensor: Located at the top of the device, protected by a white dome. This silicon photodiode measures incident light.
- LCD-skærm: A 5-digit display showing measurement values, units (lux/fc), and function indicators (e.g., AUTO RANGE, HOLD, MIN, MAX).
- Tænd/sluk-knap (tænd/sluk): Tænder eller slukker for enheden.
- CAL-knap: Used for zero adjustment.
- HOLD knap: Fryser den aktuelle aflæsning på displayet.
- fc/lx Button: Toggles between foot-candle (fc) and lux (lx) measurement units.
- RANGE knap: Manually selects measurement ranges or activates auto-ranging.
- Batterirum: Located at the rear, houses the 9V battery.

4.2 Indledende tænding
Tryk på Magt button to turn on the device. The display will illuminate and show a reading. If the battery symbol appears, replace the battery.
5. Betjeningsvejledning
5.1 Tage en måling
- Tænd enheden ved hjælp af Magt knap.
- 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)
Tryk på 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-funktion
Tryk på HOLDE knappen for at fryse den aktuelle aflæsning på displayet. Tryk på den igen for at slippe holdeknappen og genoptage livemålinger.
5.4 Zero Adjustment (CAL)
For at udføre en nuljustering:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- Tryk på 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 Valg af område
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. Vedligeholdelse
6.1 Rengøring
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 Opbevaring
