Cable Test:
At first, turn the rotary switch fully clockwise to test the battery strength.
The battery LED will light bright green if the internal battery is fully char-
ged. After changing the battery, slide the battery compartment completely
in and push the cover against the arrow direction down until it clicks into
place.
Then plug one end of the cable into the appropriate jack on the left side pa-
nel 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 connecti-
on 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 charts below to 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 correspon-
ding contacts and the chassis.
To test the cable with a banana plug, just plug each end of the cable into
the banana jacks. 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.
