GPIB/RS-232 Programming Sorensen SLM-1 Chassis
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 SLM-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 SLM-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 SLM-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 C, D and E for proper programming procedure of SL-
series electronic load modules.
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:
All SLM Modules:
CR:{HIGH|LOW}{SP}{NR2}{;|NL}
SLD Modules CR:{SP}{NR2}{;|NL}
Description:
CR:{HIGH|LOW}{SP}{NR2}{;|NL}
This command is used to set the LOW/HIGH load resistance level of SLM series AC and DC
electronic load module.
CR:{SP}{NR2}{;|NL}
This command is used to set the load resistance level of SLD-Series load module.
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 (and vice versa) for proper dynamic waveform definition; if not, the
SLM-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 SLM-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 SLM-series load module will adjust the LOW level
to be equal to the HIGH level.
