Press the CURRENT

buttons to adjust the voltage limit value
in the current display within the available range: 0.0 – 300.0 V. This value sets the lower
voltage limit that can be adjusted during normal operation. The Volt LO value must be lower
than the Volt HI value.

ON/OFF.
OFF
The system will operate as a constant voltage power source only. If the load
current exceeds the current high limit (A-HI), the unit will shut down.
ON
The system will limit the output current to a maximum value set by the current
high limit (A-HI). For loads requiring less current than the A-HI value, the unit maintains
a steady voltage output as set. If the load impedance is low enough, this function is
activated when the load current attempts to exceed the current high limit (A-HI). The
output current will then remain constant at the A-HI value and the output voltage will
decrease accordingly.
Note: The parameter settings for current and power are described in the following
section, Program Parameter Settings.
