5. Operation
Turn the rotary switch fully clockwise to test the strength of a battery. The
battery LED will light bright green if the internal battery is fully charged.
Plug one end of the cable into the appropriate jack on the left side of your
VTTEST15. Plug the other end of the cable into the appropriate jack on the
right. Now, set the rotary switch to "1" to test the connection of contact "1"
on the plug inserted into the left. If there is a connection, the green LED will
light below "1" while a yellow LED will light above the contact of the plug
connected to the right. If no LED lights, there is no connection: the left
connection will either be floating or open. Set the rotary switch to "2" to test
contact "2" etc. until all contacts have been checked. If the GROUND LED
lights, there is a connection between the corresponding contacts and the
chassis.
To test a cable with banana plugs, just plug each end of the cable into the
banana jacks. The LED will light and the unit will beep if there is a
connection between the plugs. These jacks can also be used for continuity
tests using two probe leads.
