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
the number of the channel. If the channel's type is
output. If the channel's type is
•
Examining the channel's circuit board as shown in the figure below.
The Analog 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
Jumpers located on the channel's circuit board determine what outputs are generated
when the value selected to drive the Analog Output (from the
menu items) equals the
