Parameter:
Example:
CURR:PROT:UND:DEL
This command sets the delay time for under-current protection. When the input current falls belo w the undercurrent
protection limit for the programmed delay period, the load input is off and draws no current.
Parameter:
Example:
CURR:TRIG
This command sets the input current level that is to be applied on occurrence of a trigger in the constant current mode. I f
the Electronic Load is not in the CC mode when the command is sent, the programmed TRIG level becomes a stored level
that takes effect when the Load changes to CC mode. The rate of input change is in accord with the slew rate in effect.
Parameter:
Example:
CURR:TLEV
This command sets the transient current level in CC mode. When the transient subsystem is on, the Electronic Load will
switch between the main level and transient level at a rate determined by the slew rate in effect. If the programmed
transient current level is belo w the main current level, the switchin g will not occur until the main level is belo w the value
of CURR:TLEV. The IEEE 488.1 command, "ITR" can also be used.
Parameter:
Example:
CURR:DUTY
This command sets pulse duty cycle, as a percentage of the total cycle, of continuous transient mode in CC mode. If the
Electronic Load is operating in another mode, the duty cycle is stored until the Load changes to continuous mode.
Parameter:
Example:
CURR:FREQ
This command sets pulse frequency of continuous transient mode in Hz. If the Electronic Load is operating in another
mode, the pulse frequency is stored until the Load changes to continuous mode.
Parameter:
Example:
CURR:SLEW
This command sets the current slew rate for both ranges in CC mode. The programmed slew rate is in effect for all
current changes except INP:ON or OFF.
CURR:SLEW value. To determine the actual value, use the query CURR:SLEW?.
Parameter:
Example:
CURR:LIM:MAX
This command sets and queries the maximum input current level that is to be applied immediately in the constant current
mode.
Parameter:
Example:
CURR:LIM:MIN
This command sets and queries the minimum input current level that is to be applied immediately in the constant current
mode.
