3.1 Componentes
- Sensor de luz: Located at the top of the device, protected by a white dome. This silicon photodiode measures incident light.
- Pantalla LCD: A 5-digit display showing measurement values, units (lux/fc), and function indicators (e.g., AUTO RANGE, HOLD, MIN, MAX).
- Botón de encendido (Encendido/Apagado): Enciende o apaga el dispositivo.
- Botón CAL: Used for zero adjustment.
- Botón ESPERA: Congela la lectura actual en la pantalla.
- fc/lx Button: Toggles between foot-candle (fc) and lux (lx) measurement units.
- Botón RANGO: Manually selects measurement ranges or activates auto-ranging.
- Compartimento de la batería: Located at the rear, houses the 9V battery.

4.2 Encendido inicial
Presione el Fuerza button to turn on the device. The display will illuminate and show a reading. If the battery symbol appears, replace the battery.
5. Instrucciones de funcionamiento
5.1 Realización de una medición
- Encienda el dispositivo usando el Fuerza botón.
- Asegúrese de que el sensor de luz esté limpio y sin obstrucciones.
- 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)
Presione el fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 Función MANTENER
Presione el SOSTENER Botón para congelar la lectura actual en la pantalla. Presiónelo de nuevo para liberar la retención y reanudar las mediciones en tiempo real.
5.4 Zero Adjustment (CAL)
Para realizar un ajuste a cero:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- Presione el CALIFORNIA 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 Selección de rango
The device typically operates in auto-ranging mode. To manually select a range or cycle through available ranges, press the GAMA button. The display will indicate the active range. Press and hold the GAMA 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. Mantenimiento
6.1 Limpieza
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 Almacenamiento
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. Solución de problemas
