Test Leads and Ports
Test lead ports are color-coded to the test leads and accessories provided
with your kit for easy identification and connection.
1— Common
2— Channel 1
3— Channel 2
When removing leads from their sockets, do not pull on the wire because
it can damage the leads. Pull on the plug.
Three insulated alligator clips that attach to the test leads are included. The
insulator boots are colored to match each test lead.
To install an alligator clip:
1. Remove the collar from the probe by threading it counterclockwise
off of the probe tip.
Store the collar in a safe place while not in use.
2. Thread the alligator clip onto the end of the probe.
