Column Definitions

• Time and Date: The date and time of the last hourly reading. The Electronic Pendulum Regulator logs data exclusively in Greenwich Mean Time (GMT) to prevent duplicate hourly logs when the clock keeper makes seasonal time adjustments. The Local Time column provides a familiar reference point for daily operations and local reporting.
• RTC Temperature: The temperature of the Real-Time Clock. This sits about 1°C higher than the clock room temperature.
• Clock Room Temperature: The ambient air temperature inside the clock room.
• Relative Humidity: The relative humidity level inside the clock room.
• Barometric Pressure: The local atmospheric air pressure.
• Actual BPH: The most recent actual Beats Per Hour reading.
• Target BPH: The expected or baseline Beats Per Hour rate.
• BPH Error: The difference between the target and actual Beats Per Hour rates.
• Weight Position: Indicates if a physical weight has been added to the pendulum tray or removed.
