Similarly, applying an external DC Voltage of the range between -10VDC to +10VDC to the External Analog
Control Signal Connector can provide the output current to scale between +/- full-scale current based on
the Range selected for DC Mode.
NOTE: When the UUT output voltage is positive then the External DC Voltage must range between 0 to
10VDC and when the UUT output voltage is negative then the External DC Voltage must range between
0 to -10VDC.
Pin 1 (External Reference Signal – Phase A) and Pin 4 (Return / ISO_COM) are to be connected to the
DC source to vary the output voltage for Phase A, refer to Figure 4-17.
Pin 2 (External Reference Signal – Phase B) and Pin 4 (Return / ISO_COM) are to be connected to the
DC source to vary the output voltage for Phase B, refer to Figure 4-18.
Pin 3 (External Reference Signal – Phase C) and Pin 4 (Return / ISO_COM) are to be connected to the
DC source to vary the output voltage for Phase C, refer to Figure 4-19.
The mentioned above pins are present in the External Analog Control Signal Connector (EXT ANLG)
available on the rear panel; refer to Table 4-2 for pin-out details.
4.3.4 Output Voltage Monitor (VMON)
Voltage Monitor provides functionality to monitor the scaled-down output voltage of the unit; refer to Figure
4-13 and Table 4-2 for pin-out details. The scaled-down Output voltage of each phase could be monitored
between the VMON terminals of the external analog control signal connector ( Pin-11: VMON for Phase
A, refer Figure 4-20; Pin-12: VMON for Phase B, refer Figure 4-21; Pin-13: VMON for Phase C, refer Figure
4-22 and Pin-14 (Return / ISO_COM)). Measurement of output voltage from 0 to 100% of full-scale rated
corresponds to 0 to ±10V pk.
