dated since the last scan; i.e. in a short scan cycle only high-speed sensors will
appear for most of the time, the slower ones being added at larger intervals.
This method ensures that the measuring instrument can adapt to a wide variety
of sensors - without duplicating a lot of unwanted data.
The device can be further adapted to the specific needs of the user's own ap-
plications by selecting the most suitable output cycle.
The device will automatically offer its own suggestions in a selection box; (D7
options are only available if a D7 sensor is connected).

sensor configuration, always be sustained.
This scan cycle corresponds to the conversion time for one
channel; i.e. normally with each cycle one V5 channel and
all updated D7 channels will be scanned and assigned a
time-stamp. However, as soon as all V5 channels have
been scanned at least one special measuring operation is
performed to allow the A/D converter to self-calibrate. If
thermocouples are connected, two additional internal cold
junction measuring operations will also be required.
The scan time is the scan cycle for all standard sensors at
the conversion rate including one special measuring opera-
tion and possibly two cold junction measuring operations
(see above).
nels are always scanned and displayed.
