Limitations when testing simple cables
When testing simple cables, remember these things:
• In CALC mode, you may only measure resistances up to 10 Kohms.
• In AUTO mode, the tester can only select a connection resistance up to
10 Kohms.
• Using higher Connection Resistance or Insulation Resistance settings
will slow down the testing process.

How to determine a Connection Resistance setting for complex tests.
When you set the option
Create Test From
to
Complex Assembly
, you must set
the Connection Resistance to a value that is greater than the highest wire resistance,
and less than the lowest component resistance; a resistance level that definitely sepa-
rates wires from resistors. The 1000R+ automatically sets the Connection Resistance
to a default value of 5
Ω
. You can change this value to suit your needs.
Note
: If you
don’t know what Connection Resistance setting is appropriate for the cable(s) you are
going to test, you can determine a good value by using the analyzer’s
CALC
feature
as shown here.
To determine the proper Connection Resistance setting for a cable, do these things:
1. Set the
Create Test From
option to
Sample Cable
.
2. Set the Connection Resistance setting to
CALC
.
3. Turn on the analyzer, and learn the cable.
4. When the display prompts
