-
’ and put an external short link between
'-
' and ‘
W
’ as shown in figure
-11. Similarly connect for all other channels.
Notes:
1.
When wiring RTDs, lead length and diameter must be chosen such that lead length are equal
and that each lead exhibits no more than 10 Ohms resistance between the LmNet and the
RTD.
2.
For Input connections, high quality, low resistance contacts must be used which are suitable
for dry operations.
