Sliding Average Value
The measurement device records average values for the measured voltages, currents and powers including a time stamp.
Moving or sliding averages always apply to the last elapsed time interval, starting from the current time. The average values are recalculated every minute.
Example: Setting 15 min
When the values are queried at 10:18, the average values for the interval 10:03 to 10:18 are sent (accurate to the second for the last 900 s).
Voltage values
Time interval for capturing the average voltage values.
Current values
Time interval for capturing the average current values.
Power values
Time interval for capturing the average power values.
Note
The time intervals defined here are used not only for the moving averages, but also in other contexts when the average (or minimum/maximum value) can be selected in a field. When a voltage, current or power is selected, the associated interval is used.
The intervals of the moving average are considered, for example, on the following configuration cards:
Periphery > Analog output
Logic > Comparator
Further notes:
The average values and the associated 200 ms minimum and maximum values can be read out via Modbus addresses.
The meter overwrites the Modbus addresses with the average values and the associated minimum and maximum values for each interval, even if the previous values were not retrieved.
In addition to the measured values, the time stamp is also provided in Modbus addresses. More information on this can be found in the user manual and the Modbus address list available for download at www.janitza.de.
