INP:PROT:CLEar Channel-Specific Input Command
Description
This command resets the electronic load latched protective features (such as overvoltage,
overcurrent, overpower, etc.). If an electronic load protective circuit has shut down the
input and no INPut:OFF command has been sent, INPut:CLEar will restore the input to
the ON state and restore the previously existing operating mode and its parameters. Of
course, if the cause of a shutdown condition is not corrected, it will reoccur.
If a trigger is received during the time a protection circuit has shut down the input, any
triggered levels (CURR:TRIG, RES:TRIG, etc.) are stored and will be transferred to the
main level after the protection is cleared. Triggers received during protective shutdown are
also applied to the Transient Subsystem. This ensures that after the shutdown is cleared,
the transients on the restored channel will still be synchronized with those of other
channels.

INP:SHORt Channel-Specific Input Command/Query
Description
This command applies the equivalent of an electronic short across the input of the
electronic load. The actual condition of the electronic load under a short condition depends
on its operating mode as follows:
Mode of Operation Shorted Condition
High-Range CC Mode MAX current
Low-Range CC Mode MAX current
Low-Range CR Mode MIN resistance
Middle-Range CR Mode MIN resistance
High-Range CR Mode MIN resistance
CV Mode MIN voltage
If a mode or current or resistance range is changed, the short will be reapplied to the new
mode or range. If a trigger is received while SHORt is ON, any triggered levels (CURR
TRIG, RES:TRIG, etc.) are stored and will be transferred to the main level after SHORt
is programmed OFF. Triggers received during SHORt:ON are also applied to the
Transient Subsystem. This ensures that after the short is programmed off, the transients on
the shorted channel will still be synchronized with those of channels that had remained
unshorted.
Executing INPut:SHORt does not affect any programmed settings and the electronic load
will return to them when the short is removed. This command is subordinate to
INPut:[STATe]. If INPut[:STATe] is programmed OFF, then the effect of
INPut:SHORt:ON will not be observed until INPut[:STATe]:ON is sent to the electronic
load.
