*If the voltage is incapable of loading as the value set, it can add load limit current or lower
down the limit current of DC Source.

7.3.3.2 Checking Medium Voltage Range

A. Connect the Load module, DC source, DMM and current shunt as Figure 7-1 shows.
Use DMM (V) to measure the voltage passing through the module's input terminal. Be
careful in making connections so that contact resistance voltage drop will not affect the
readings.
MODE
B. Press till VFD shows CV and press
indicator.
EDIT
C. Press to set load voltage and press
voltage output and limit current settings are based on the voltage/current values listed in
Table 7-12.
LOAD
D. Next, press
passing through the negative input terminal.
