1736/1738 Users Manual Options to configure the logging session: • Duration and manual start • Duration and set start date/time • Set start date/time and set end date/time A memory gauge shows the memory used by recorded sessions and stored screenshots in black. The memory required for the new session is shown in green. When the new logging session will not fit in the available memory, the gauge turns from green to red. If you confirm the selection, the Logger will adjust the averaging interval accordingly. Interval of the average calculation Select the time interval when a new average value is added to the logging session. The available intervals are: 1 s, 5 s, 10 s, 30 s, 1 min, 5 min, 10 min, 15 min, 30 min. A shorter interval provides more details at the cost of higher memory consumption. Examples of when a short interval is useful: • Identify duty cycle of frequently switching loads • Energy cost calculation of production steps The Logger recommends an interval based on the duration to get the best balance between resolution and data size. A memory gauge shows the memory used by recorded sessions and stored screenshots in black. The memory required for the new session is shown in green. In the case where the new logging session will not fit in the available memory, the gauge turns from green to red. It is still possible to confirm the selection but the Logger will adjust the duration accordingly. Demand Interval Electrical suppliers use this interval to measure the customer demand. Select an interval to get energy costs and the maximum demand value (average power measured over a demand interval). A value of 15 minutes is normal. If you don't know the average interval, select 5 minutes. You can recalculate other interval lengths offline using the Energy Analyze Plus software. Note This value is not available for load studies. 34
