2.10.1 2V analog output
The 2V ANALOG OUTPUT provides a scaled 0-2V output
that is non-inverting in the volts mode. Connections for using
this output are shown in Figure 2-40. For a full-range input,
the output will be 2V; typical examples are listed in
Table 2-16. The 2V ANALOG OUTPUT signal is not
corrected during calibration. Gain errors of up to 15% may
appear at this output, depending on function and range
selection.
Note that the output impedance is 10kΩ; to minimize the
effects of loading, the input impedance of the device
connected to the 2V ANALOG OUTPUT should be as high
as possible. For example, with a device with an input
impedance of 10MΩ, the error due to loading will be
approximately 0.1%.
