Types of Tests
Using the Cirris 1000HN, you can perform two different kinds of tests. These are:
1. Simple tests.
2. Hipot tests.
Simple Tests
Simple tests are used for testing cables made up of only wires and connectors. These
cables have no resistors, capacitors, diodes, or any active circuitry. Set the Connection
Resistance to a low number (typically less than 10
Ω
). Depending on the capacitance
of the cable, set the Insulation Resistance to a higher setting.
This table will give you general guidelines for setting up simple tests. You can adjust
the settings to meet your specific needs.

in AUTO, you may be testing
at a much higher threshold
than you want. Use CALC to

it yourself.
