Interpreting test results
String summary (for a string of 12 V jars)
The test results in the STRING SUMMARY (STRING STATISTICS on the printout) are averages for
the jar posts and straps in the string. If you tested without a reference value, dashes appear in the
fi
elds that are marked in this example with asterisks (
*
).
