11.7 Digital-to-Analog Converter (DAC) Output Configuration
11.7.1 Identifying the
Output Type
An AC/AC-LVDT Input channel is available with one of two types of digital-to-analog
(DAC) outputs: voltage or current. You can determine which type of output a channel
has by one of three ways:
•
Consulting the instrument’s Customer Information Sheet
•
Examining the
SYSTEM MENU
->
CONFIGURATION
->
CHANNEL
nn
TYPE
menu item where nn is
the number of the channel. If the channel’s type is
AC-AC LVDT V
, it has a voltage
output. If the channel’s type is
AC-AC LVDT I
, it has a current output.
•
Examining the channel’s circuit board as shown in the figure below.
11.7.2 Channel Menu
Items
The DAC Output can be driven by any channel’s track, peak or valley value.
See the “Channel Menu” section earlier in this chapter for a complete listing of SETUP
menu items available on the
DAC. SETUP
sub-menu.
11.7.3 Output Selection
Jumpers located on the Main Circuit Board determine what outputs are generated
when the value selected to drive the DAC Output (from the
DAC. CHANNEL
and
DAC. SOURCE
menu items) equals the
DAC. FULL SCALE
and
DAC. ZERO SCALE
settings.
