6-6 Buffer Model 2700 Multimeter/Switch System User’s Manual
Storing readings
Perform the following steps to store readings:
1. Set up the Model 2700 for the desired configuration.
2. Press the STORE key.
3. Use the , , Δ, and ∇ keys to specify the number of readings to store in the
buffer (2
to 55000). Pressing the AUTO key sets the readings count to 000000.
NOTE With buffer auto clear disabled, the only valid buffer size values are 55000 and
000000 (which clears the buffer). Any other buffer size value is ignored.
4. Press ENTER. The asterisk (*) annunciator turns on to indicate the buffer is
enabled. It will turn off when the storage is finished.
5. The buffer can be stopped at any time by pressing EXIT.
NOTE Stored readings are not lost when the instrument is turned off. To clear the
buffer, set the reading value to “000000” and press ENTER.
For remote programming, the continuous storage mode can be selected. After
the buffer fills, operation wraps around to the beginning of the buffer (location
#0) and starts to overwrite old reading data (see TRACe:FEED:CONTrol
command in
Table 6-1).
Recalling readings
Readings stored in the buffer are displayed by pressing the RECALL key. The readings are
positioned at the left side of the display, while the buffer location number (reading
number) and timestamps are positioned at the right side.
Perform the following steps to view stored readings and buffer statistics:
1. Press RECALL. The “BUFFER” annunciator indicates that stored readings are
being displayed. The double-arrow annunciator indicates that more data can be
viewed with the ,
, Δ, and ∇ keys.
2. As shown in Figure 6-1 and Figure 6-2, use the , , Δ, and ∇ keys to navigate
through the reading numbers, reading values, statistics, and timestamps. For any of
the buffer statistics (standard deviation, average, peak-to-peak, minimum, and
maximum), the “STAT” annunciator is on.
NOTE The longer you hold in the Δ or ∇ key, the faster you will scroll through the
buffer. After a while, scrolling speed will increase by incrementing (or
decrementing) the buffer reading number by 100, and then finally by 500. When
you get close to the desired reading number, release the
Δ or ∇ key. Again press
and hold in the
Δ or ∇ key to scroll one reading at a time.
