1. Navigate to the main page of the Q3. Assuming the subject
cables are disconnected, you should see the message shown to
the right.
2. Connect the subject cables to the Q3. On the round subject cable
connector, the indentation must line up with the arrow on the
back panel of he Q3 to allow proper insertion of the connector.
3. Take the test resistor out of its storage tube. Connect the clips
from one of the cables to the wire on one side of the resistor.
The red clip must be between the black clip and the resistor.
4. Connect the other two clips to the wire on the other side of the
resistor in the same manner. It does not matter which cable gets
connected to which wire—the test resistor cannot be connected
“backwards”. What matters is that both clips from the same ca-
ble get connected to the same side of the resistor.
The cables should be tested regularly or any time you receive readings that “don’t look
right.” RJL Systems receives calls from new customers asking how regularly we recommend
testing the cables. A set of subject cables should last a long time, if they are used gingerly
and treated with respect. Testing them once every few months is not a bad idea.

TESTING SUBJECT CABLES
The subject cables are delicate. Abuse can cause breaks in the wires. Frequently, this leads
to incorrect resistance and reactance values and readings that rapidly change or “jump
around”. Be careful not to tie them in knots or to fold them over. When storing the subject
cables, they should be coiled loosely and placed in their storage pouch.
Once the subject cables have been connected to the test resistor, you should see the screen
change to show you the current resistance, reactance, impedance, and phase angle. These meas-
urements may appear before all four clips are connected to the resistor, but it is imperative that
all four clips do get connected before proceeding with the test.
