Setting the buffer style
You can control the amount of information that is saved with each reading in the reading buffer by
selecting the buffer style when you create the buffer.
• Compact: Store more readings at lower precision, with relative timestamps and no formatting
information. Maximum 27,5000,000 readings. Once you store the first reading in a compact
buffer, you cannot change certain measurement settings, including range, display digits, and
units; you must clear the buffer first.
• Standard: Store readings with full precision and formatting information. Maximum 11,000,000
readings.
• Full: Store the same information as the standard style, plus additional information, such as the
ratio component of a DCV ratio measurement.
• Writable: Manually write external data to a reading buffer. For more information, see Writable
reading buffers (on page 3-34). You cannot select this buffer style from the front panel; you must
use remote commands.
• Full Writable: Manually write external data to a reading buffer with two values per buffer index.
You cannot select this buffer style from the front panel; you must use remote commands.
You can only select the style of the reading buffer when you first create the buffer.
Not all remote commands are compatible with the compact, writable, and full writable buffer styles.
Check the Details section of the command descriptions before using them with any of these buffer
styles.
Using the front panel to set the buffer style:
1. Press the MENU key.
2. Under Measure, select Reading Buffers. The MANAGE READING BUFFERS window is
displayed.
3. Select New. The Buffer Name dialog box is displayed.
4. Type a name for your buffer and select OK. The Style dialog box is displayed.
