7.2.2 Extended diagnosis
In addition to the standard DP diagnostic message, the measuring system also
provides an extended diagnostic message according to the PNO measuring system
profile. This message varies in length depending on the chosen nominal configuration.
In the configurations designated "TR-mode", the diagnostic message corresponds to
PNO Class 2.
The following pages provide a general overview of the available diagnostic
information. Which individual options your measuring system actually supports can be
read out from the device itself.
