Accessibility: [Main menu] Measurements -> [Sub menu] Manage...

When selecting this option a table of all available measurements (per active user) appears. This table has three columns: name, date and value, which are measure's basic parameters. You can sort the table (ascending/descending) by pressing table's labels. You can also filter records by entering a value in the filter textbox and pressing filter. The filter is applied on name values. To remove filtering, clear textbox's content and press filter
Example: in the following screenshot all measurements which name contains "Wa" were shown. And afterwords sorted by date.

Add button is always enabled and Edit button is enabled only when a record selected. Using those buttons you can Add/edit measurements. For more help regarding add/edit measurements please follow this link.

Delete button is enabled when a measurement selected and as its name suggests, it allows to eliminate measurements.
