Effects of reset and power cycle on buffers
The instrument clears the default buffers when a reset command is sent or when the power is turned
off and then turned on again.
The instrument deletes all user-defined buffers when a reset command is sent or when the power is
turned off and then turned on again.
Buffer fill status
There are several different ways to determine buffer fill status from the front panel.
As shown in the following figure, the Active buffer indicator (on page 2-14
) displays buffer fill status
and the STATISTICS swipe screen (on page 2-12) displays buffer statistics.
Figure 59: BUFFER STATISTICS swipe screen and active buffer indicator
You will receive the event code 4915, "Attempting to store past capacity of reading buffer," in a popup
message when a buffer that is set to fill once is full.
You can turn the display of messages on or off. Refer to System Event Log menu (on page 2-34) for
information about turning the messages on or off.
The MANAGE MEASURE BUFFERS window displays buffer fill status. For example, the status in the
following figure indicates that:
• defbuffer1 is completely filled and is overwriting readings in the buffer as additional readings
are made
• defbuffer2 is empty
• testData is 100% full and no more readings are being stored in testData.
