High Resistance Errors
The tester displays a High Resistance error when a cable interconnection has too much
resistance.
High Resistance errors are caused by:

Defects in the cable, such as partially inserted or dirty connector contacts and poorly
crimped wires.

High resistance in the adapter or tester connector contacts. In this case, the tester
connectors that interface with the adapters may be worn or damaged and need to be
replaced.

A “Connection Resistance” setting too low for the tested assembly. In this case, the wire
or contact resistance is greater than the “Connection Resistance” setting, but less than
the “LV Insulation Resistance” setting.

A component, such as a resistor, exists in the cable which has not been learned in the
test program.
Intermittent Errors
The 1100R+ Tester looks for Intermittent Errors in a cable during the Intermittent Test.
Intermittent errors include the same short and open errors found in the Low Voltage cable test,
as described in the previous section.
What’s the difference between Intermittent Errors and Low Voltage Errors?
To be an Intermittent Error, the tester must sense the cable wire pattern:
1. Was good,
2. Then changed to bad,
3. Then changed back to good.
Intermittent Errors are caused by:

Cable defects that are detected only when the cable is moved or wiggled during the test.

The ultimate causes are the same as those described in the previous section for opens
and shorts.
