C. Insert the wire into the pin. Check that the
insulation is in the strain relief crimp area
but not in the bare wire crimp area. Crimp
the pin onto the wire. A good crimp is
very important. Poor crimps will cause
jumpy readings and are the biggest
source of problems.
D. Pull Test: Pull (approximately 3 to 4 pounds) on the wire near the connector with one hand while
holding the connector with the other hand. If the wire pulls out of the connector, you must start over
using a new connector.
E. A well soldered connection at the crimp can be reliable. Soldering a TC wire requires a lot of heat
to produce a good solder connection. Also, when soldering a TC wire each wire should be scraped
with a knife to expose fresh metal just before crimping and applying solder. Fluxing the TC wire can
also help. Do not use acid core solder or acid flux.
