3.3.1 Output Voltage Setting
On the MAIN page (refer to section 3.3.1), press the item VOLTAGE to enter into the
output voltage setting page (refer to Figure 3.4). Users can see the set voltage and
change it by using the keypad for different testing conditions. The output voltage
setting page also shows the maximum and minimum of set value for the output
voltage. Press to confirm and finish setting. Press to clear all the input
value or press to modify setting.

provides two levels of output voltage range, including High level and Low level.
High level allow the maximum output setting voltage range to be 0~310V and Low
level has the range of 0~155V. Please not that when set the output voltage at 120V,
the maximum output current at High level is only the half of the maximum output
current at Low level.

single-phase models)
Notice
For three-phase models, when the icon is shown on the bottom left of the
MAIN page, each phase’s output voltage setting is synchronized with each other. As
any of the U, V, or W phase’s voltage changes, the other two phase’s voltages
change accordingly as well. When the icon is shown, each phase’s output
voltage can be set independently, which means U, V, or W phase’s voltage can be
different from each other. To switch between independently adjustable phase
voltage and synchronized phase voltage, press the icon or to switch in
between two different settings.
