[ENTER], the display will indicate DONE and the instrument
will return to the RUN mode. If you use the [UP] button and
[ENTER] to select RETURN POINTS=YES, you may now apply
the same loads again but in reverse order. This will allow the
instrument to measure and partially eliminate any hysteresis
that may be present in the transducer. After the loads have
been applied again, the display will indicate DONE and the
instrument will return to the RUN mode.
10.5.7 DAC SETUP Sub-Menu
This sub-menu contains four items that control the Digital-to-Ana-
log Converter (DAC) output of the channel.
DAC. CHANNEL Menu Item
This chooses which channel will drive the DAC output. Normally,
the DAC located on a particular channel will be driven by that
channel, but that need not be the case. For example, if several
channels were assigned to load cells on a weighing platform, the
sum of all channels could (mathematically) drive one channel’s
DAC output.
If the DAC is set-up to be driven by its own channel’s tracking
value, the Analog Output will have the frequency response speci-
fied by the channel’s FREQ. RESPONSE menu item. Otherwise,
the Analog Output will operate more slowly.
