5. Operating Instructions
5.1 Navigating the Interface
The FPM-02 features a user-friendly interface with a 2-inch HD color screen. Use the navigation buttons (up, down, left, right, OK/Enter) to move through menus and select options. The device supports both English and Chinese languages, which can be selected in the settings menu.
5.2 Taking Measurements (Illuminance, Temperature, Humidity)
Upon powering on, the device typically defaults to the main measurement screen, displaying real-time values for illuminance (Lux/FC), temperature (°C/°F), and relative humidity (%).
- Illuminance: Ensure the light sensor (located at the top of the device) is unobstructed and pointed towards the light source or area to be measured. The device will display the light intensity in LUX or FC.
- Temperature & Humidity: The internal sensors continuously monitor ambient temperature and humidity. Allow a few minutes for readings to stabilize after significant environmental changes.
5.3 Real-time Data and Curve Recording
The device can display real-time data and record changes over time, presenting them as a curve. Access this feature through the main menu to visualize trends and fluctuations in environmental conditions.
5.4 Setting Alarm Thresholds
You can set custom alarm thresholds for Lux, temperature, and humidity. If a measured value exceeds or falls below the set threshold, the device will trigger an alert. Refer to the device's settings menu to configure these thresholds.
5.5 Sleep Mode and Data Logging
To conserve battery, the device features a configurable sleep mode. It also includes data logging capabilities, allowing you to store measurement data for later review and analysis. Consult the user manual for detailed instructions on activating and managing these functions.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure the light sensor and display are kept clean for accurate readings.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the battery is partially charged (around 50%) to prolong its lifespan.
- Battery Care: Avoid fully discharging the lithium battery frequently. Recharge the device when the battery level is low.
