Section 11: Rework and Guided Assembly / Removing shorts between nets

1000HN User’s Guide / page 52

analyzer may prompt

Intermittents

as you rework the connection. To clear this

prompt, press the

Memory

button on the back of the analyzer.

Removing shorts

between nets

If the analyzer detects short circuits in the cable or harness you are testing, it will tell
you where to make cuts to correct the shorts. This will happen if two nets should
become shorted. To correct a detected short, do these things:

The analyzer will prompt

Cut JX-XX From JX-XX

, where X indicates the

adapter positions and pin number.

Locate the short between the nets, and remove it.
