1. BASE PLATE
This fits into the top of the transformer tester and has the following features:
• Fitted with 40 node contacts which connect to the 40 test node pins on the top of
the tester.
• Moulded indents on the bottom surface to act as drill guide marks for ease of
drilling to fit:
4mm safety sockets as a universal or for specific applications.
Termination posts
• Provision for drilling through and fitting inserts for the attachment of a clamp in
either the left or right hand position.
• Slots moulded into the base to support wiring to the connection points from the
nodes.
• Four mounting pillars to hold the cover plate (supplied). The cover plate fits on to
the underside of the fixture by four snap rivets to protect the wiring from
accidental damage. It locates into moulded sockets in the Fixture Board by a
simple press-fit action.
The fixture parts are made using a high-pressure injection moulding process in a
material that is suitable for soldering temperatures and the high voltage that will exist
during use.
