You can now choose a midrange setting from the high and low resistances shown in
your printout. For example, this printout shows that net 4 contains a resistor, and has a
resistance of 20 ohms. Net 1, which is only a wire connection, has a resistance of .1
ohm. All other nets have a zero resistance. Therefore, when you set Connection
Resistance for testing a complex assembly, you could select any value from .1 ohm to
20 ohms. As you can see, the automatic default setting of 5 ohms falls well within
this range.
7. Set the Connection Resistance to a value greater than the highest wire resistance,
and less than the lowest component resistance.
How to set the options to learn a complex assembly
To set the options for learning a complex assembly, do these things:
• If the default Connection Resistance setting of 5 ohms is not appropriate
for the cable you want to test, set it to a value between the highest wire
resistance, and the lowest component resistance in the cable.
• Set the
Create Test From
option to
Complex Assembly
, then turn off
the analyzer.
How to learn a complex assembly
1. Install the correct cable adapters, then connect the assembly you want to learn to
the analyzer
2. Turn on the analyzer to learn the cable assembly.
The analyzer first prompts Learning Cable , as it learns all interconnections in the
cable which have resistances up to the Insulation Resistance setting you have
