Note
The measurement system (MD7) must match the measurement system speci-
fied in the other DBs.
The measurement system raster (MSR) is the smallest distance unit in the
active system of measurement.
If at some point you have failed to take this precaution:
1. Delete all data blocks of the relevant channel (which do not match the
2. Modify the other data blocks on the programming device.
3. Reload the data blocks to the FM 453.
