1. Rhagymadrodd
This manual provides comprehensive instructions for the safe and effective use of the PCE Instruments PCE-170 A Light Meter. This device is designed for measuring illuminance (lux or foot-candles) in various environments, such as offices, factories, and outdoor settings. It features a wide measurement range, fast response time, and a compact design for ease of use.
Darllenwch y llawlyfr hwn yn drylwyr cyn defnyddio'r ddyfais a'i gadw i gyfeirio ato yn y dyfodol.
2. Gwybodaeth Diogelwch
Observe the following safety precautions to prevent injury and avoid damage to the device:
- Peidiwch â gwneud y ddyfais yn agored i dymheredd eithafol, lleithder na golau haul uniongyrchol.
- Osgowch ddirgryniadau neu effeithiau cryf.
- Peidiwch â cheisio agor na newid y ddyfais. Cyfeiriwch yr holl waith cynnal a chadw at bersonél cymwys.
- Keep the light sensor clean and free from obstructions to ensure accurate readings.
- Tynnwch y batri os na fydd y ddyfais yn cael ei defnyddio am gyfnod hir er mwyn atal gollyngiadau.
- Gwaredu batris a'r ddyfais yn unol â rheoliadau lleol.
3. Cynnyrch Drosview
The PCE-170 A Light Meter consists of a main unit with a display and control buttons, and an integrated light sensor.

3.1 Cydrannau
- Synhwyrydd Golau: Located at the top of the device, protected by a white dome. This silicon photodiode measures incident light.
- Arddangosfa LCD: A 5-digit display showing measurement values, units (lux/fc), and function indicators (e.g., AUTO RANGE, HOLD, MIN, MAX).
- Botwm Pŵer (Ymlaen/Diffodd): Yn troi'r ddyfais ymlaen neu i ffwrdd.
- CAL Button: Used for zero adjustment.
- Botwm DAL: Yn rhewi'r darlleniad cyfredol ar yr arddangosfa.
- fc/lx Button: Toggles between foot-candle (fc) and lux (lx) measurement units.
- Botwm YSTOD: Manually selects measurement ranges or activates auto-ranging.
- Adran Batri: Located at the rear, houses the 9V battery.

4. Gosod
4.1 Gosod Batri
- Lleolwch glawr adran y batri ar gefn y ddyfais.
- Slide the cover open or unscrew it, depending on the model.
- Insert one 9V battery, observing the correct polarity (+/-).
- Amnewid y clawr adran batri yn ddiogel.

4.2 Pŵer Cychwynnol
Gwasgwch y Grym button to turn on the device. The display will illuminate and show a reading. If the battery symbol appears, replace the battery.
5. Cyfarwyddiadau Gweithredu
5.1 Cymryd Mesur
- Turn on the device using the Grym botwm.
- 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)
Gwasgwch y fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 Dal Swyddogaeth
Gwasgwch y DALWCH botwm i rewi'r darlleniad cyfredol ar yr arddangosfa. Pwyswch ef eto i ryddhau'r daliad ac ailddechrau mesuriadau byw.
5.4 Zero Adjustment (CAL)
I berfformio addasiad sero:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- Gwasgwch y 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 Dewis Ystod
The device typically operates in auto-ranging mode. To manually select a range or cycle through available ranges, press the YSTOD button. The display will indicate the active range. Press and hold the YSTOD 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. cynnal
6.1 Glanhau
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 Storio
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. Datrys Problemau
| Problem | Achos Posibl | Ateb |
|---|---|---|
| Nid yw dyfais yn troi ymlaen. | Batri marw neu wedi'i osod yn anghywir. | Gwiriwch bolaredd y batri neu rhowch fatri 9V newydd yn ei le. |
| Display shows "OL" (Overload). | Light intensity exceeds the current measurement range. | Switch to a higher measurement range using the YSTOD button, or move to a less intensely lit area. |
| Darlleniadau anghywir. | 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. |
| Mae'r arddangosfa'n wag neu'n fflachio. | Batri isel. | Amnewid y batri 9V. |
