Switching
The switching function is used to switch between two preset load currents. Switching can be
performed in CC mode and CR mode.
Switching is suitable for transient-response testing of regulated DC power supplies and
similar devices.
To use the switching function, you need to set a switching level and a switching interval and
then turn on the switching function. You can configure switching while the load is on or off.
When you execute switching, a trigger signal is produced from the TRIG OUT terminal on the
front panel.
Example in CC Mode
Setting the switching level
You can set the switching level to a current or conductance value or to a percentage.
■
Setting the switching level to a current or conductance value
1
Press LEVEL.
The LEVEL key lights, and in CC mode, the current can be set; in CR mode, the
conductance can be set.
2
Turn the rotary knob to set the switching level.
■
Setting the switching level to a percentage
The specified current or conductance level is equivalent to 100 %.
1
Press % (SHIFT+LEVEL).
The LEVEL key lights, and you can set the switching level to a percentage.
2
Turn the rotary knob to set the switching level (0.0 % to 100.0 %).
