Cable Tester Pro
Ordercode: D1909
Testing a cable
At first, turn the rotary switch fully clockwise to test the battery condition. The battery LED will light bright
green if the internal battery is fully charged.
Then plug one end of the cable into the appropriate jack on the left side panel of the cable tester. Plug
the other end of the cable into the appropriate jack on the right side panel. Set the rotary switch to “1”
to test the connection of contact 1 on the plug inserted into the left side panel.
If there is a connection, the Green LED will light below “1” and a Yellow LED will light above each contact
on the right side plug connected to “1” on the left side plug. Use the tables in appendix 1to verify proper
cable connections.
If no LED lights then there is no connection and the left side contact “1” is “floating” due to design or an
“open” in the cable.
Set the rotary switch to “2” to test contact 2, and so on, until all contacts have been checked.
If the Ground LED lights then there is a connection between the corresponding contacts and the chassis.
To test the cable with a banana plug, just plug each end of the cable into the banana jacks. The LED will
light and the unit will beep a tone if there is a connection between the plugs. These banana jacks can
also be used for continuity tests using two probe leads.
