2.7 Analog Output Configuration
2.7.1 Identifying the
Output Type
A RTD 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 SSSSYYYYSSSSTTTTEEEEMMMM MEN MEN MEN MENUUUU -> CCCCOOOONNNNFFFFIIIIGGGGUUUURRRRAAAATTTTIIIIOOOONNNN -> CCCCHHHHAAAANNNNNNNNEEEELLLL nn TTTTYYYYPPPPEEEE menu item where
nn is the number of the channel. If the channel’s type is RRRRTTTTDDDD VVVVoooouuuutttt , it has a volt-
age output. If the channel’s type is RRRRTTTTDDDD Io Io Io Iout ut ut ut , it has a current output.
• Examining the channel’s circuit board as shown in the figure below.
2.7.2 Channel Menu
Items
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

2.7.3 Output Selection
Jumpers located on the channel’s circuit board determine what outputs are gener-
ated when the value selected to drive the Analog Output (from the
