Model 2700 Multimeter/Switch System User’s Manual Buffer 6-3
With buffer auto clear disabled, the only two valid buffer size values are 55000 and
000000. Buffer size 000000 clears the buffer. Entering any other buffer size value resets
the buffer size to 55000.
NOTE
If the buffer is empty when the Model 2700 is turned off, buffer auto clear will
enable when it is turned back on.
If the buffer is not empty, the instrument will power up to the last auto clear
setting. Keep in mind that if the instrument powers up with buffer auto clear off,
buffer size is fixed at 55000. You will have to enable auto clear to change the
buffer size.
The auto clear setting (on or off) is not affected by SYSTem:PRESet or *RST
(front panel or remote operation). However, front panel FACTory defaults
enables buffer auto clear.
Enabling/disabling buffer auto clear

If you change the state of buffer auto clear, the buffer will clear.
3. To change the state of buffer auto clear, press to place the cursor on the present

For remote programming, the TRACe:CLEar and TRACe:CLEar:AUTO
commands are used to clear the buffer (
