Remote Programming Sorensen SLH-Series DC High Power Electronic Load
5.3
GPIB/RS-232 COMMAND DESCRIPTION
5.3.1 Setting Commands
CURRENT Level
Purpose:
The load current setting in Constant Current mode.
Command Syntax:
CC:{LOW|HIGH}{SP}{NR2}{;|NL}
Description:
CC:{LOW|HIGH}{SP}{NR2}{;|NL}
Note:
a. The load current data must include the decimal point; otherwise, this command will not
execute. The load current level can be programmed up to the sixth place after the
decimal point.
b. The HIGH level load current MUST be higher than the LOW level load current (and vice
versa) for proper dynamic waveform definition; if not, the SLH-series Electronic Load will
adjust and limit the programmed values to be equal. The adjustment matches the
second input value to the first input value.
This means that if the value for the LOW level is input first, and then the HIGH level
value is input as less than the programmed LOW level, the SLH-series load module will
adjust the HIGH level to be equal to the LOW level. If the value for the HIGH level is
input first and the LOW level value is input as higher than the programmed HIGH level,
the SLH-series load module will adjust the LOW level to be equal to the HIGH level.
c. If the programmed load current level is over the maximum rated specification, the full
scale current will be sent to the load module.
d. Engineering unit for load current is Amps.
e. Please refer to Appendices proper programming procedure of SLH-series electronic load.
Example:
CC:LOW 1.8 set LOW level load current to 1.8 A.
CC:HIGH 25.123456 set HIGH level load current to 25.123456 A.
RESISTANCE Level
Purpose:
The load resistance setting in Constant Resistance mode.
Command Syntax:
CR:{HIGH|LOW}{SP}{NR2}{;|NL}
Description:
CR:{HIGH|LOW}{SP}{NR2}{;|NL}
Note:
a. The load resistance data must include the decimal point; otherwise, this command will
not execute. The load resistance level can be programmed up to the sixth place after the
decimal point.
b. The HIGH level load resistance MUST be higher than the LOW level load resistance
