Conguration Functions
7.1 VON Function
The DC load can be set to only turn on if the voltage is above a set value (VON set) under congure menu by pressing
+ . There are two types of VON function: “Living” and “Latch”. The following will have detailed description for
the two types.
NOTE
VON set is used to ensure an electronic system under test will not have power applied unless the supply voltage is above
a certain value. If you have no such testing request, do not set this value arbitrarily. If your instrument can not work
normally, for example, set CC=1 A, after turn on the input while the current is still 0 A instead of setting value 1 A,
then you should check VON set rstly. If VON set is not 0 V, then please modify to 0 V.
VON LIVING MODE In Living mode, when power is applied to the DC load, the voltage must rise above VON setting
before the load draws current from the source. If the voltage below VON setting on the load’s
terminals, the load will turn o input.
VON LATCH MODE In Latch mode,as before,the load will turn on only when the voltage exceed VON setting,but once
on,it will now stay on,even if the voltage drops to zero.
