Sequence of the listed probes acc. ABC.
A probe can only be assigned to one channel at a time, so it is not possible to e.g. assign stored probe
PRT1
to channel 1 and 2 at the same time. This means that if a probe, which is currently assigned to a channel, is
assigned to another channel, it is no longer assigned to the first channel. If no probe is explicitly assigned to a
channel, the default probe for the channel type will be used. For PRT channels, this is 4W-PT100, for TC channels
TC(K).
