2-14 Connections Model 6485 and 6487 User’s Manual
Analog output
The Model 6485/6487 has an analog output on the rear panel. The ANALOG OUT pro-
vides a scaled, inverting ±2V output. A full-scale reading corresponds to ±2V output.
`^rqflk Connecting COMMON or ANALOG OUT to earth while floating the
input may damage the instrument.
Connections for using this output are shown in Figure 2-14 (Model 6485) and Figure 2-15
(Model 6487). For a full-scale input (i.e. 2mA on the 2mA range), the output will be -2V.
The 2V analog output signal is not corrected during calibration. The Model 6485 output
impedance is 1k, while the Model 6487 output impedance is <100. To minimize the
effects of loading, the input impedance of the device connected to the ANALOG OUT
should be as high as possible.
