point scans and for output of the memory. This output format can be pro-
grammed in the function
which all measured values are listed one below the other; there is also the
´Columns´ format listing them next to one another; this provides a clear, easy-
to-understand, and space-saving printout. For this latter format the printer is
switched over automatically to compressed character mode. There is also the
´Table´ format which is suitable for further processing using a spreadsheet
program; (see print layouts, Manual 6.1).

12.1.3 Measuring rate, continuous measuring point scan

As and when necessary the measuring rate (conversion rate) for measuring
point scans can be changed, via the
setting of 10 mops to 2.5 / 50 / 100 mops (see Manual 6.5). There is also an op-
tion (SA0000-Q4) for setting the measuring rate to 400 mops but this is only
possible for passive selector switch boards and only for 1 measuring point at a
time.
Semi-continuous measuring point scan
The option of scanning only the selected measuring point (non-continuous) is
no longer provided because ignoring all the other sensors may easily lead to er-
rors. However, it may be useful, especially when numerous sensors are being
used, to assign preferred priority to the selected measuring point and update its
measured value more frequently, e.g. for the purposes of analog output or mea-
sured value smoothing. The default setting is therefore now no longer the "non-
continuous " but the "semi-continuous" measuring point scan, i.e. all mea-
suring points are continuously scanned but the selected measuring point is
scanned in each 2nd measuring operation. This reduces by half the total sam-
pling rate required with continuous measuring point scanning.
