Front Panel Operation
2-70
2.8.4 Buffer multiple displays
Math operations performed on buffered readings are avail-
able when readings are recalled. Just press NEXT DISPLAY
to view the math operation on the bottom line of front panel
display, in the following order:
1. MAX  maximum reading in buffer, for example:
MAX=+1.635968e+00 at RDG# +00090
Notes:
A. Display response may be slow due to calculation of
statistics for large buffers.

B. Exponents are in terms of primary units of function
on top line (i.e., volts, not millivolts).
2. MIN  minimum reading in buffer, for example:
MIN=+1.627611e+00 at RDG# +00012
3. AVG  This math operation displays the mean value of
the buffered readings, for example:
AVG=+1.6345e+00
