Keithley 2010 User Manual

Buffer operations
The Model 2010 has a buffer to store from two to 1024 readings and units. It also stores the
channel number for scanned readings and overflow readings. In addition, recalled data includes
statistical information, such as minimum, maximum, average, and standard deviation.
NOTE Statistics are not calculated when an overflow reading has been stored in the buffer.
The buffer fills with the requested number of readings and stops. Readings are placed in the
buffer after any math operations are performed. Buffered data is overwritten each time the
storage operation is selected. The data is volatile; it is not saved through a power cycle.
The following paragraphs discuss storing and recalling buffered data.
