Types of Tests
Using the Cirris 1000R+, you can perform two different kinds of tests. These are:
1. Simple tests.
2. Complex 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.

Calculating
Resistances Only
CALC NA Use CALC to help you determine where
to set your Conn. Resis. threshold. In
CALC, the 1000R+ displays the actual
resistance measured between points.
NOTE: you should CALC several cables
to get a good sampling, then set your
own threshold. DO NOT use CALC for
testing!
Automatic Test AUTO NA
(Automatically
set to 5 M
Ω
)
AUTO selects a Conn. Resis. threshold
for you. It takes the highest resistance
measured between any two points and
adds 20%. Warning: If you get a Sam-
ple Cable with high resistance when
learning in AUTO, you may be testing at
a much higher threshold than you want.
Use CALC to determine a better Conn.
Resis. threshold, then set it yourself.
Fast Test 1 K
Ω
1 K
Ω
The fastest possible test. This setting
effectively emulates a continuity tester.
Typical Test 0.5
Ω
100K
Ω
Use these settings when low connection
resistance is important and insulatiion
resistance is not critical. Low connec-
tion resistance may require more care-
ful adapter maintenance.
Stringent Test 0.5
Ω
5M
Ω
Use these settings for stringent and
slow testing, when you require low con-
nection resistance and extremely good
insulation resistance. This test requires
careful adapter maintenance
