Determining a test pattern
Introduction
Before you attach the cable to the jar, you should determine a pattern for testing to make testing
a consistent and fluid process.
Posts and straps
You must test all posts and straps on a jar before testing the next jar in the string. You can test jar
posts in any direction as long as you are consistent for each jar. However, you must test a jar post
and then the strap that connects it before you test the next post on the jar. Figure 5 displays the
pattern you should test posts and straps in.
Figure 5. Pattern for testing posts and straps
Step 1 shows a connection between the first set of positive and negative posts. Step 2 shows a
connection between the negative post and the strap end attached to the next jar. This connection
ensures that you test the entire strap and its connections. Steps 3 and 4 and steps 5 and 6 repeat
steps 1 and 2.
String
After you test the posts and straps for a jar, you should test the next jar in the direction the straps
and jar cables connect the jars in. Figure 6 shows an example of how to test jars in a string.
