Overview
The Cirris 1000R+ has seven test option settings which you set to meet your testing
requirements. In this section, we’ll tell you what each of the settings means.
Create Test From
Gives you the option to create a new test setup from a new Sample Cable, your last
test setup, or by learning a complex cable that contains resistors and/or diodes in addi-
tion to ordinary wire connections.
SAMPLE CABLE
: Use this setting to learn standard simple cables (cables that
contain only wires and connectors).
LAST TEST SETUP
: Use this setting when you need to use the same test setup each
time you turn on the analyzer. Useful when testing large batches of the same type
cable. Will help protect your test setup from a power failure, or if you accidentally
turn on the analyzer with an untested cable connected. When you select this option
but do not install the correct connector adapters, the analyzer will alternately prompt
for the correct adapters and display
Create Test From Last Test
Setup to remind
you of the setting.
COMPLEX ASSEMBLY
: Use this setting to learn a cable that contains resistors,
diodes, or divider networks in addition to ordinary wires and connectors. When you
use this setting, the Connection Resistance refers to the resistance level that definitely
separates wires from resistors. The analyzer sets this to 5
Ω.
You may change the
setting to meet your needs. Using the Connection Resistance CALC mode may help
you determine a good setting.
Connection
Resistance
Specifies the maximum resistance a connection can have and still be considered
good. For example, if you set the Connection Resistance to 10
Ω
, the analyzer will
consider all connections with resistances less than 10
Ω
as good, and those with resis-
tances greater than 10
Ω
as bad.

AUTO mode : When you set the Connection Resistance to AUTO, the 1000R+
measures the resistance of each connection in your Sample Cable, then automatically
sets the Connection Resistance threshold to a value 20% higher than the largest
resistance measured in the Sample Cable. The 20% margin of error is increased for
resistances less than 1
Ω.
CALC mode :Settting the Connection Resistance to
CALC
causes the 1000R+ to
measure the resistance of the connections in the Sample Cable in the same way you
would measure them with an ohmmeter. In this mode, the analyzer can only measure
resistances up to 10K
Ω
. After the analyzer calculates the resistance of the Sample
Cable, it prompts RESISTANCE READY . Press the
Display/Print
switch to display
all resistances measured below 10Kohms.
