Appendix 8 Concerning Noise Countermeasures

Appendix

Blocking Noise from External Sources

Keep signal lines away from noise sources

Keep input signal lines (of the thermocouple) away from wiring that is a noise source
(such as power lines, etc.), and make any permanent installation with as much sep-
aration as possible; for example, by running wires through a separate duct.

Use shielded twisted pair wiring

It is effective to use shielded twisted pairs for the input signal lines (of the thermo-
couple). Twisted pairs are effective for preventing electromagnetic induction, and
shielded wires are effective for preventing electrostatic induction.
The shielded wires should basically be grounded on the signal source side. If it is not
possible to connect the signal source to ground, connect it to the chassis GND on
the LR8431-20. Note that doing so has no effect if the LR8431-20 is not itself con-
nected to ground through the three-prong power cord, etc.
Shielded twisted pair wires for the thermocouple can be obtained from thermocouple
manufacturers.

The shielding for the signal lines
is grounded on the signal side

Keep the signal lines (of the thermocouple) away from wiring that is a noise source
(such as power lines, etc.). It is also possible to shield the signal lines from elec-
trostatic coupling and to block noise by grounding the shield.

Thermocouple

If the signal side is not grounded or if it is grounded inadequately, connect the instru-
ment to ground. Also ground the shielding for the signal wires on the instrument side
securely.
