DAC. FULL-SCALE
This sub-menu contains four items that control the Digital-to-Analog (DAC) output
of the channel.
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 various transducers in a
system, 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 specified by the channel's
menu item. Otherwise, the Analog Output will operate more slowly.
This designates the data source of the channel monitored by the analog output.
Each channel has three data sources: the live tracking value (TRACK), its highest
value (PEAK), and its lowest value (VALLEY).
The options for this menu item are:
• " " means the live tracking value of the channel.
TRACK
• " " means the highest value of the channel since the peak/valley detector
PEAK
was last cleared.
• " " means the lowest value of the channel since the peak/valley detector
VALLEY
was last cleared.
If the DAC is set-up to be driven by its own channel's tracking value, the Analog
Output will have the frequency response specified by the channel's
menu item. Otherwise, the Analog Output will operate more slowly.
This specifies what value, in engineering units, corresponds to zero output on the
Analog Output.
"Zero output" might be 0 Volts, 2.5 Volts, 5 Volts, 4 mA or 12 mA depending on if
the channel has a voltage or current output and how it is configured. See "Analog
Output Configuration" on page 94 for details.
This specifies what value, in engineering units, corresponds to full output on the
Analog Output.
"Full output" might be 5 Volts, 10 Volts or 20 mA depending on if the channel has
a voltage or current output and how it is configured. See "Analog Output Configu-
ration" on page 94 for details.
