Exa mple:
“RES:LIM:MAX 50” – sets maximum resistance input level to 50 Ohms.
RES:LIM:MIN
This comma nd sets a nd queries the minimum input resista nce level tha t is to be a pplied immedia tely in the CR mode.

Voltage Programming Functions
This subsystem progra ms the constant volta ge mode functions of the Electronic Loa d. The IEEE488.1 command,
“VSET” and “SET” (if current active mode is CV mode), can also be used.
VOLT
This comma nd sets the input volta ge level tha t is to be a pplied immedia tely in the consta nt volta ge mode. If the
Electronic Loa d is not in the C V mode when the command is sent, the progra mmed level is sa ved to be a pplied when the
Loa d cha nges to CV mode. The ra te of input cha nge is in a ccord with the slew ra te in effect.
Pa ra meter:
0 to ma ximum va lue; MIN; MAX
Unit: Volt
Exa mple:
“VOLT 120” – sets the voltage level to 120V.
VOLT:PROT
:
OVER
This command sets a protection limit to the input volta ge tha t the Electronic Loa d will shunt. When the input current
rea ches the programmed volta ge limit for the pro gra mmed dela y period, the Electronic Loa d input is off a nd shunts no
volta ge.
Pa ra meter:
0 to ma ximum va lue; MIN; MAX
Units: Volt.
Exa mple:
“VOLT:PROT:OVER 12”- sets the over voltage protection to 12 Volts.
VOLT:PROT
:
OVER:DEL
This comma nd sets the delay times in millisecond for over-volta ge protection. When the input volta ge rea ches the
progra mmed volta ge limit for the progra mmed dela y period, the Electronic Loa d input is off a nd shunts no volta ge.
Pa ra meter:
0 to ma ximum va lue; MIN; MAX
Units: ms
Exa mple:
“VOLT:PROT:OVER:DEL 1000”- sets the over voltage protection delay to 1000 ms.
VOLT:PROT:UND
This comma nd sets an under volta ge protection limit to the input volta ge tha t the Electronic Loa d will shunt. When the
input volta ge fa lls below the under volta ge protection limit for the progra mmed dela y period, the loa d input is off a nd
shunts no volta ge.
Pa ra meter:
0 to ma ximum va lue; MIN; MAX
Units: Volt.
Exa mple:
“VOLT:PROT:UND 1.5”- sets the under voltage protection to 1.5Volts.
VOLT:PROT
:
UNDER:DEL
This comma nd sets the dela y times in millisecond for under-volta ge protection. When the input volta ge fa lls below the
progra mmed the under volta ge protection limit for the progra mmed dela y period, the Electronic Load input is off a nd
shunts no volta ge.
Pa ra meter:
0 to ma ximum va lue;
Units: ms
Exa mple:
“VOLT:PROT:UNDER:DEL 1000”- sets the under voltage protection delay to 1000 ms.
VOLT:TRIG
This comma nd sets the input volta ge level tha t is to be a pplied on occurrence of a trigge r in the constant volta ge mode. If
the Electronic Loa d is not in the CV mode when the comma nd is sent, the progra mmed TRIG leve l becomes a stored
IMM level tha t takes effect when the Loa d cha nges to CV mode. The ra te of input cha nge is in a cc ord with the sle w ra te
in effect.
Pa ra meter:
0 to ma ximum va lue; MIN; MAX
Unit: Volt
Exa mple:
“VOLT:TRIG 100” – sets the voltage trigger value to 100V.
VOLT:TLEV
This command sets the tra nsient volta ge level in C V mode. When the tra nsient subsystem is on, the Electronic Loa d will
switch between the ma in level a nd tra nsient level a t a ra te determined by the slew ra te in effect. If the programmed
