Measure Data Buffers menu
From this screen you can save, resize, and clear buffers. You also can set buffer fill mode and
statistics functions.
Set the maximum number of readings the buffer can store (2 to 2,500). Note
that when you resize a buffer, the readings contained in that buffer are
cleared.
Select Always to have the buffer fill continuously, overwriting old data when
the buffer is filled.
Select Next to have the buffer stop collecting data when it is filled (no data is
overwritten).
Select Never to have the buffer stop collecting data.
Select statistics to apply to the readings in the buffer. Available statistics:
 Minimum: Minimum value
 Maximum: Maximum value
 Peak-Peak: Maximum value - minimum value
 Mean: Average
 Std Dev: Standard deviation
Select whether to apply statistics calculations to current or voltage readings.
You can only specify one of them at a time.
Enable or disable autoclear for the buffer. When autoclear is enabled, the
buffer will automatically clear when the storage process starts.
Select the data elements to be shown on the graph and data sheet screen.
Available data elements:
 Value: Voltage and current reading
 Time: The timestamp for the data point
 Number: Reading number
 All: Voltage and current reading, timestamp for the data point, and
reading number
Save the buffer to a .csv file, which can be opened by a spreadsheet
program.
Clear all the data in the buffer.
