CURR 25 Immediate commands for 25-ampere input
CURRENT:LEVEL 25
CURR:TRIG 25MA Commands for 25 mA input on
CURRENT:LEVEL:TRIGGERED 25E-3 occurrence of a trigger
CURR 30; :CURR:TRIG MIN Set input to 30 Amps now and minimum current when
trigger occurs
Query Syntax
CURR? CURR? MAX CURR? MIN

Returned Parameters
<NR3> CURR? and CURR:TRIG?
return the presently programmed current levels. After a trigger or
ABORt, CURR:TRIG? returns the same value as CURR? .
CURR? MAX, CURR? MIN, CURR:TRIG? MAX and
CURR:TRIG? MIN return the maximum and minimum
programmable LEVel and TLEVel values for the present range.

CURR:PROTection Channel-Specific Current Limiting Command/Query
Description
This command sets a limit to the input current that the electronic load will sink. A current
limit may be specified for the single electronic load or for a channel of the multiple
electronic load. When the input current reaches the current limit for the specified delay
period, the input of the electronic load or channel is shut off and draws no current. This, in
effect, provides a "soft circuit breaker" for the input current. The
INPut:PROTection:CLEar command (or front panel key) re-enables the input current.
The trigger activated current functions (CURR[:LEV]:TRIG and CURR:TLEV)
automatically keep track of incoming triggers while the input is shut down and will
respond to the trigger as soon as the protection fault is cleared.
The :PROTection:DELay command specifies the time that the input current may equal or
exceed [:LEVel] before the soft circuit breaker is actuated. The PROTection:STATe
command enables or disables the soft circuit breaker function.
Note
If the soft circuit breaker function causes the input to shut down, it will not affect
INP[STATe]. If INP:STAT is programmed ON, it will remain so even after the
CURR:PROT has turned the electronic load off.
