Before programming the temperature data, the element positions must be known (refer to figures 4.1 and 4.2).
The element positions of an MPT (Multiple Pt100 spot) element are listed on the test certificate of the MPT
element. If the test certificate is not at hand, the element positions can also be calculated from the Model
selection code on the identification label.
Position 11 of the Model selection code defines the ‘Position of the lowest element’, and Positions 16 through 19
list the ‘Position of the highest element’ (unit is cm).

Positions 9 and 10 of the Model selection code show the number of Pt100 elements of the MPT probe.
Alternatively, the number of elements can be obtained by counting the number of wires of the MPT probe (not
counting the two black wires).
