Input On/Off Operation
During front panel operation, press the On/Off key to switch the input on/off state. Input On/Off
operation will not affect the present settings. The load/unload speed of On/Off operation is not
dependent on the rise/fall slew rate. When in remote control mode, you can send SCPI command
“INPut ON” to turn the input on (refer to MDL Series Programming Guide for more information on
remote commands).
Von Operation
The Von voltage value can be set to control the voltage turn on state for the electronic load. When
the input voltage exceeds the Von voltage value, the electronic load’s input state turns on.
This function can protect a DUT when its voltage goes below a specified level. For example, when
testing a power supply’s discharge, you can set the voltage level for the power supply to begin and
end discharging.
There are two different modes of Von operation, set by the Von LATCH parameter.
When Von LATCH is disabled, the electronic load will begin sinking current if input voltage exceeds
Von voltage. When the input voltage drops below the Von voltage value, the electronic load will
stop sinking current and the input will turn off.
