Significance
Instrument address in the bus structure, selectable only by
software.
Significance
Value in engineering unit of minimum sensor temperature. E.g.
-200 for Pt 100. See technical data section for each sensor limit.
Value in engineering unit of maximum sensor temperature. E.g.
850 for Pt 100. See technical data section for each sensor limit.
For Tc inputs, compensation must be provided for ambient
temperature existing at the cold junction point. This is normally
provided by a precision sensor installed internally to the
TMD 834 transmitter. However the user may choose to set this
temperature compensation as an external parameter. See also
next field V2H3.
A value in engineering units must be entered here if in previous
field V2H2 is selected "external". Value may range from
-40 to 85 °C.
Contains information about product code of transmitter.
Contains information related to the instrument software version.
see chapter 5.2
Entering code 333 in this location, matrix will be unlocked.
Entering a three code digit number ≠ 333 the matrix is locked
(except V9H9). The measuring point is then protected against
accidental or unauthorised entries.
An 32 characters alpha-numerical string is available to enter
measuring point designation.
