2.6 Sensor Input (Measuring Input)

Precautions

 

• Do not run input wires together with power cables

 

• When shielded cable is used, it should be grounded at one point only

 

• Any external components (such as zener barriers, etc) connected between sensor and input terminals may cause errors in measurement due to excessive and/or un-balanced line resistance or possible leakage currents

 

• The sensor input is not isolated from the logic outputs & digital inputs

 

• Pay attention to line resistance; a high line resistance may cause measurement errors

 

• A single sensor should not be connected to more than one instrument. Sensor break operation could be severely compromised
