Volts
The Volts screen allows the user to set the input voltage for the selected
table point in the conversion table, from 0.00 to 10.50. The default table is
a two-point table with point 1: 0.00 V = 000.0 U and point 2: 10.00 V =
10.0 U.
In the Main Menu, choose Instrument Controls > I/O Configuration >

Analog Input Config > Select Channel > Select Point > Volts.
User Value
The User Value screen allows the user to set the output value for the
corresponding input voltage for the selected table point in the conversion
table, from -9999999 to 99999999. The default table is a two-point table
with point 1: 0.00 V = 000.0 U and point 2: 10.00 V = 10.0 U.

Temperature compensation provides compensation for any changes to the
instrument's output signal due to internal instrument temperature
variations. The effects of internal instrument temperature changes on the
analyzer's subsystems and output have been empirically determined. This
empirical data is used to compensate for any changes in temperature.
When temperature compensation is on, the display shows the current
internal instrument temperature (measured by a thermistor on the Interface
