CONNECTION DIAGRAMS

Connections are to be made with the instrument housing installed in its proper location.

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.

NOTE:

1)Don’t run input wires together with power cables.

2)For TC wiring use proper compensating cable preferable shielded.

3)when a shielded cable is used, it should be connected at one point only.
