When Moving Average is Enabled , the PT-55 will calculate a moving average based on a preset
number of sample readings. The Pull Test Graph in the Main Screen can now display a graph
with either the raw individual readings ( blue ) or the Moving Average ( pink ) or both.
When the Moving Average is between the upper and lower control limits, the test result will be
PASS . If the Moving Average exceeds those limits, the test result will be FAIL .
Note: If the Moving Average is between the preset upper and lower limits but the individual
readings exceed those limits, the test result will still be PASS .
When Moving Average is enabled, the user must select
the number of
Samples/Average . This can be set from
2-10 .
The Plotted Data field allows the user to choose what
data appears in the Main Screen graph when a test is
run. The options are Raw (individual test readings),
Average and Both .
