3.4.1. ANALOG OUTPUT
Refer to Figure 3-4 for the location of the analog output, which can be configured
for 0-5V voltage or 4-20 mA current output. See Section 3.4.1.1 for details on
verifying or changing the analog output hardware configuration.
The analog output is automatically scaled to the range of the instrument. See
Section 5.2.4.2 for information on changing the range of the monitor.
The monitor has an analog output step-test mode that can be used for verifying the
operation of the analog output and calibration of external measurement equipment.
This mode is described in Section 5.2.3.1.
