of the analyzer. The prompt will change to

Resistance Ready

When the prompt changes to

Resistance Ready

, press

Display/Print

. A list of

the measured resistances in the cable will be printed.

From your printout locate these resistances:

•

The highest measured resistance for nets that you know contain only
wires.

•

The lowest resistance for nets that you know containing components
which exhibit resistance.
