notes
- External temperature input is insulated neither from instrument
internal circuitry nor from residual current input
- The terminals T- and IΔ12 are connected internally, do not connect
signals of different potential !
- Maximum length of connection cable is 3 meters ! Otherwise, EMC-
immunity of the instrument can be degraded.
