Operation Overview 29
Short On/Off
A load can simulate a short circuit at its input by turning the load on with full-scale current. The short circuit can be toggled
on/off at the front panel (
key) or via the GPIB (INPUT:SHORT ON|OFF command). The short on/off
change uses the slew rate setting of the active mode and range.

The actual value of the electronic short is dependent on the mode and range that are active when the short is turned on. In
CV mode, it is equivalent to programming zero volts. In CC mode, it is equivalent to programming full-scale current for the
present CC range. In CR mode, it is equivalent to programming the minimum resistance for the present resistance range.
Note that turning the short on in CV mode may cause the load to draw so much current that the software current limit
operates, which may turn the input off.
Turning the short circuit on does not affect the programmed settings, and the input will return to the previously programmed
values when the short is turned off.
Pressing the Short on/off key with certain user applications may cause damage to the equipment being
tested, which may result in personal injury. Contact your Agilent Sales and Service office if you need
to have the Short on/off key disabled.
