88 SEND ALL SAMPLES UNTIL NEXT SPC OFFSET
This function tells the control to start collecting weld data for
all welds. This function should follow the SPC Offset
function in the weld schedule because it is still necessary to
assign a starting bin number.
Weld data collection continues until the control executes
another schedule containing this function (without the offset
function), to reset the global data collection process.
This function overrides the global Data Collection Sample Size
and Data Collection Sample Frequency setup parameters.
These are described next.

DATA COLLECTION SAMPLE SIZE: 05 (1–99)
DATA COLLECTION SAMPLE FREQUENCY:0100(1–9999)
These two parameters set a global command which allows
the weld control to sample data for analysis at controlled
intervals.
The sample size is the amount of weld data collected for
analysis (number of consecutive welds, per bin). The sample
frequency is the total number of welds per bin, where data
was collected (the samples are taken from).
For example, by setting the Data Collection Sample Size
parameter to 2 and the Data Collection Sample Frequency
parameter to 8, the control will collect weld data for 2
consecutive welds (in bin #1), and flag the XWSS to retrieve
the data. It will then collect data for 6 more cycles (without
flagging XWSS) before starting the process again.
The example table on the next page is for Bin #1 ONLY.
