Available thermocouples:
J, K,R, S, T, C, D, B, E, L, L-GOST,
U, G, N,
Pt20Rh-Pt40Rh
ITS90 or custom linearization
Respect polarity
For extensions, use a compensated
cable
Input PT100/JPT100 - 2-wires connection
[with option auxiliary input = 1]
Attention:
with this type of connection the
line resistance can introduce
measurement error, we recommend
that you use wires of adequate screen.

Attention:
with this type of connection the line
resistance can introduce measurement
error, we recommend that you use
wires of adequate screen.
The resistance of the three wires must
be equal, the line resistance must be
less than 20 ohm.
