A) MEASURING INPUTS
NOTE: Any external components (like zener
barriers etc.) connected between sensor and input
terminals may cause errors in measurement due
to excessive and/or not balanced line resistance or
possible leakage currents.
TC INPUT

NOTE:
1) Don’t run input wires together with power
cables.
2) For TC wiring use proper compensating cable
(for example, J TC extension wire for J TC)
preferable shielded.
3) when a shielded cable is used, it should be
connected at one point only.
