Measure Reading Buffers menu
The Reading Buffers menu allows you to view the list of existing reading buffers
and select one to be the active buffer. You can also create, save, delete, resize, and
clear buffers from this screen.
To create a new reading buffer, select New. The new buffer is automatically set to be the active
buffer.
To adjust settings for a specific buffer, select the buffer. The Settings screen for that buffer is
displayed. A brief description of the options is provided in the following table.
Setting Description
Buffer
Selects an existing buffer to configure.
New
Creates a new buffer that you name and configure.
Style
When creating a new buffer, specifies the style of buffer to create.
Standard: Store readings with full accuracy with formatting,
maximum 11,000,000 readings
Compact: Store readings with reduced accuracy (6.5 digits) with
no formatting information, 1 μs accurate timestamp, maximum
27,500,000 readings
Full: Store the same information as standard, plus additional
information, such as the ratio component of a DCV ratio
measurement
Capacity
Sets the maximum number of readings that the buffer can store.
Note that when you resize a buffer, the readings contained in that
buffer are cleared.
Fill Mode
Continuous: Fills the buffer continuously and overwrites old data
when the buffer is full.
Once: Stops collecting data when the buffer is full (no data is
overwritten).
Clear
Clears data from the selected buffer.
