DAC. SOURCE Menu Item
This designates the data source of the channel monitored by the
analog output.
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.
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.
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 “Analog Output Configuration” on page
36 the for details.
If the UPDATE DAC SETUP menu item is set to “ON” and the DAC.
CHANNEL menu item is set to this channel, this menu item may
be automatically updated by a transducer’s Signature Module. If
the UPDATE DAC SETUP menu item is “OFF”, a transducer’s Signa-
ture Module will not change this menu item.
DAC. FULL-SCALE Menu Item
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 “Analog Output Configuration” on page 36 for details.
If the UPDATE DAC SETUP menu item is set to “ON” and the DAC.
CHANNEL menu item is set to this channel, this menu item may be
automatically updated by a transducer’s Signature Module. If the
UPDATE DAC SETUP menu item is “OFF”, a transducer’s Signature
Module will not change this menu item.
10.5.8 SIGNATURE MODULE Sub-Menu
UPDATE SIG.MOD? Menu Item
Updates the information stored in the transducer’s Signature
Module with any new settings that is entered into the instrument
with the SETUP menus. The settings that will be updated are:
• FULL SCALE MV/V
• FULL SCALE VALUE
• SHUNT CAL VALUE
• DISPLAY. UNITS
Note that changes made to the instruments display setup (such
as decimal point and count-by settings) are not updated into the
Signature Module.
Updating enters these new settings from the instrument into the
Signature Module. If you do not update the Signature Module,
connect a different transducer to the instrument and then re-
connect the original transducer again, the instrument will revert to
the settings that are stored inside the Signature Module.
The options for this menu item are:
• “NO” will not update the Signature Module.
• “YES” will display WORKING, update the Signature Module,
then display DONE.
DEFAULT SIG.MOD? Menu Item
This menu item will overwrite any user settings in the Signature
Module with the original default settings. The Signature Module
always maintains a copy of the original default settings that were
created at the factory.
The options for this menu item are:
• “NO” will not restore original default settings.
• “YES” will display WORKING, update the Signature Module, with
the original factory settings, then display DONE.
UPDATE DAC SETUP Menu Item
This menu item determines whether or not the DAC. FULL SCALE
and DAC. ZERO SCALE Analog Output settings are overwritten with
information from a Signature Module when a new transducer is
detected by the instrument.
The options for this menu item are:
• “YES” will allow a newly detected Signature Module to update
the Analog Output settings.
• “NO” will not allow automatic updating of the Analog Output
settings.
