3.4 Key Lock Function

Press the combined keys
and VFD will display a Lock label. In this functional state, all keys except the
following keys are invalid. Pressing
cancel the lock.

3.5 Short-circuit Analog Function

The electronic load can simulate a short circuit at the input terminal to test
whether the protection function of the DUT can operate normally when the
output terminal of the DUT is short-circuited.
Press
operation does not affect the current set value. When you press
(Short) again, the electronic load returns to the original setting state.
In the short-circuit status, the actual consumed current value depends on the
operating mode and current range of the load. In CC, CW and CR modes, when
the current is within the maximum range, the short-circuit current is the input
current value. When the current exceeds the maximum range, the maximum
short-circuit current is 110% of the range. In the CV mode, the short circuit is
equivalent to setting the constant voltage value of the load to 0V.
