6-2 Buffer Model 2700 Multimeter/Switch System User’s Manual
Buffer overview
The Model 2700 has a data store (buffer) to store from 2 to 55,000 readings. The
instrument stores the readings that are displayed during the storage process. Each
timestamped reading includes the buffer location number and a timestamp.
The data store also provides statistical data on the measured readings stored in the buffer.
These include minimum, maximum, average, peak-to-peak, and standard deviation.
NOTE When scanning, the readings are automatically stored in the buffer.
NOTE The various instrument operations, including buffer operation, are performed on
the input signal in a sequential manner. See
“Signal processing sequence,”
page D-2, for details. It includes flowcharts showing where in the processing
sequence that buffer operations occur.
Front panel buffer
Auto clear
With buffer auto clear enabled, the buffer is cleared (readings lost) before a new storage
operation starts. The buffer can be manually cleared by setting the number of readings to
store (buffer size) to 000000.
NOTE When editing the reading count over the front panel, press AUTO to reset the
count to 000000. You can then press <ENTER> to clear the buffer.
When buffer auto clear is disabled, the buffer is not cleared and the buffer size is set to
55000. Each subsequent storage operation appends the readings to the buffer. When the
buffer fills with 55,000 readings, the storage process stops. The 55,000 readings are
cleared before the next storage operation starts.
