Statistical Processing
The statistical processing function calculates peak, bottom, average, peak-to-peak, stand-
ard deviation, N output, HH output, HI output, GO output, LO output, and LL output values.
Statistical Processing Items Available
• Statistical processing is possible independently for each program number and OUT
(output).
• Statistical processing under RS-232C control is possible.
• The results of statistical processing can be printed out.
• Refer to page 7-14 for the timing chart of statistical processing.
Setting Range
The following statistical processing items are selectable. Refer to page 5-62 for the
setting method.
• OFF:
The statistical processing function is not used.
• EXT: External synchronous setting is used.
• 1000 (value): Internal synchronous setting is used. The setting range is between 2
and 9999999.
Statistical-processed measured value RUN mode
Normal, auto peak hold, auto bottom hold,
auto peak-to-peak hold Measured values determined by
TIMING input.
Peak hold, bottom hold, peak-to-peak hold,
average hold, sample hold 1, sample hold 2 Measured values determined by
TIMING input.
Self-timing hold Measured values determined by self-
timing.
Note: • A statistic value is refreshed when the statistical processing is finished.
• When statistical processing is activated, the statistic value will be held until
the LS-7600 Series is turned OFF or the program is initialized or reset.
• If there is no measured value (i.e., the display is “---.-----“), no statistical
processing is possible or calculated into memory.
• NG output can be printed but not displayed.
