14.3 Setup Procedure
If you are not familiar with operating the instrument in the SETUP
menu mode, see "SETUP Menu mode" on page 7. A listing of all
menu items is given in "Setup Menu Reference" on page 77.
•
Step 1: Determine if you have a Voltage DAC Output channel
or a Current DAC Output channel.
Check the instrument's Customer Information Sheet, or see
"Identifying the Output Type" on page 68.
•
Step 2: Wire the readout instrument to the channel's connec-
tor.
See the "Wiring" section earlier in this chapter for details.
•
Step 3: Select the value (channel and source) used to drive
the Analog Output
See the "Channel Menu" on page 67 for details.
•
Step 4: Select the full-scale and zero-scale settings used to
drive the Analog Output.
See the "Channel Menu" on page 67 for details.

14.5 Channel Menu
Each DAC Output channel is configured and calibrated via its
channel menu. Detailed instructions on operating the instrument
in the SETUP Menu mode can be found in "SETUP Menu mode"
on page 7. A diagram of all menus is located in "Setup Menu
Reference" on page 77.
14.5.1 DAC SETUP Sub-Menu
This sub-menu contains four items that controls the analog output
of the channel.
DAC. CHANNEL Menu Item
This chooses which channel will drive the Digital-to-Analog Con-
verter (DAC) output.
DAC. SOURCE Menu Item
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:
•
"TRACK" means the live tracking value of the channel.
•
"PEAK" means the highest value of the channel since the
peak/valley detector was last cleared.
•
"VALLEY" means the lowest value of the channel since the
peak/valley detector was last cleared.
DAC. ZERO-SCALE Menu Item
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 the "Digital-to-Analog Output" section of
this chapter for details.
This menu item is not automatically updated by another channel's
Signature Module equipped transducer.
DAC. FULL-SCALE Menu Item
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 config-
ured. See the "Digital-to-Analog Output" section of this chapter
for details.
This menu item is not automatically updated by another chan-
nel's Signature Module equipped transducer.
