CONTINUOUS - In the screens shown above, CONTINUOUS is the currently selected "Sampling Mode"
which has also caused the "Sampling Period" for the Control Chart to be set at "Continuous". "Continuous"
is the default sampling mode and enables the Weld Sentry to save all monitored data in SPC History. When
a sub group size is entered the sampling period is automatically changed to the same number so that data is
continuously saved.
PERIODIC - Move the cursor to “Sampling Mode” and press [CHNG] to change “Continuous” to
“Periodic”. This enables the Weld Sentry to save monitored data only periodically, as defined by the
“Sampling Period”. The Sentry will save the number of welds equal to the "Sub Group Sample Size" and
then will not save any more welds until the number of welds equal to the “Sampling Period” have been
monitored. Note: All welds will always be monitored, Periodic Sampling Mode only reduces the number of
welds which are saved in SPC History. In the examples below, 3 welds will be saved for every 9 welds
monitored.
When the Sampling Mode is changed, the Weld Sentry will erase any prior data in SPC History, because the
data would no longer be comparable. The following screen is displayed.
If you do not wish to proceed or cancel history and want to cancel the changes to SPC Sampling Mode,
press [ENTER] when the answer is NO. To continue with the changes, and understand that history will be
erased, press [CHNG] to change the answer to YES, and then press [ENTER].
