COLD CONTACTS
The TE-3000-HD contains three choices for the “cold contact” part of the circuit. One cold
circuit must be connected with the BNC connector to the Alloy Sorter before taking a test. Be
sure the cold circuit makes solid contact with test metal first, then make contact with a hot
probe.
• The Alligator Clip: Hands-free contact with the metal surface of small and large parts.
Clipping it on ensures good electrical connection.
• The Heavy Copper Block: Choice for non-clamp or delicate plated surfaces. It can also
hold cylindrical bearings, spherical bearings, and small parts. The heavyweight of the
block also allows it sit securely on a workbench. Use the 6 foot male to male BNC to
connect the TEAS.
• The Wand: Requires two hands. Is very fast to use. Leave test metal in place and move
Wand and Hot Probe to part. Wand contacts metal first then thermal probe.
