3.3 Input On/Off Control

[ On/Off ] button on the front panel is used to manually toggle the instrument
between its set mode and an infinite impedance state, i.e control input on and
off. [ On/Off ] button lighted indicates the load input is on, meanwhile the [
indicator will disappear.

3.4 Short-circuit Analog Function

Short circuit simulation and short circuit current measurement:you may press
[ Shift ] + [ 1 ] botton to emulate a short state.It can be used to check whether
the tested instrument's short protection is avaiable.
In short mode,the DC load will draw maximum current from the DC supply in
any of the four operation modes(CC,CV,CW or CR).In CC,CV,or CR mode,you
may press [ Shift ] + [ 1 ] to stop short.The DC load will return to its previous
operation.However,in CW mode,the short current will continue to be drawn.To
stop the short,you must press the [On/Off] key after you press [ Shift ] + [ 1 ].
When emulating a Short in CC, CW or CR mode, the maximum allowable short
current is equal to the 110% of current range. Under CV mode, short circuit
current is equivalent to that constant voltage value of load is 0 V.
