Example:
RES:LIM:MIN
This command sets and queries the minimum input resistance level that is to be applied immediately in the CR mode.

Voltage Programming Functions
VOLTage
This subsystem programs the constant voltage mode functions of the Electronic Load. The IEEE488.1 command,
"VSET" and "SET" (if current active mode is CV mode), can also be used.
VOLT
This command sets the input voltage level that is to be applied immediately in the constant voltage mode. If the
Electronic Load is not in the C V mode when the command is sent, the programmed level is saved to be applied when the
Load changes to CV mode. The rate of input change is in accord with the slew rate in effect.
Parameter:
Example:
VOLT:PROT:OVER
This command sets a protection limit to the input voltage that the Electronic Load will shunt. When the input current
reaches the programmed voltage limit for the pro grammed delay period, the Electronic Load input is off and shunts no
voltage.
Parameter:
Example:
VOLT:PROT:OVER:DEL
This command sets the delay times in millisecond for over-voltage protection. When the input voltage reaches the
programmed voltage limit for the programmed delay period, the Electronic Load input is off and shunts no voltage.
Parameter:
Example:
VOLT:PROT:UND
This command sets an under voltage protection limit to the input voltage that the Electronic Load will shunt. When the
input voltage falls below the under voltage protection limit for the programmed delay period, the load input is off and
shunts no voltage.
Parameter:
Example:
VOLT:PROT:UNDER:DEL
This command sets the delay times in millisecond for under-voltage protection. When the input voltage falls below the
programmed the under voltage protection limit for the programmed delay period, the Electronic Load input is off and
shunts no voltage.
Parameter:
Example:
VOLT:TRIG
This command sets the input voltage level that is to be applied on occurrence of a trigger in the constant voltage mode. If
the Electronic Load is not in the CV mode when the command is sent, the programmed TRIG level becomes a stored
IMM level that takes effect when the Load changes to CV mode. The rate of input change is in acc ord with the slew rate
in effect.
Parameter:
Example:
VOLT:TLEV
This command sets the transient voltage level in C V 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
