Sorensen SLM-4 Chassis GPIB/RS-232 Programming
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 resistance level is over the maximum rated specification,
the full scale resistance will be sent to the load module.
d. Engineering unit for load resistance is Ohms.
e. Please refer to Appendices C, D and E for proper programming procedure of SL-
series electronic load modules.
Example:
CR:LOW 0.123 set LOW level load resistance to 0.123 OHM.
CR:HIGH 3.456789 set HIGH level load resistance to 3.456789 OHM.
VOLTAGE Level
Purpose:
The load voltage setting in Constant Voltage mode.
Command Syntax :
SLM DC Modules: CV:{HIGH|LOW}{SP}{NR2}{;|NL}
SLD Modules:
CV:{SP}{NR2}{;|NL}
Description:
CV:{HIGH|LOW}{SP}{NR2}{;|NL}
This command is used to set the load voltage level of SLM-series DC electronic load
modules.
CV {SP}{NR2}{;|NL}
This command is used to set the load voltage level of SLD-series electronic load modules.
Notes :
a. The load voltage data must include the decimal point; otherwise, this command
will not execute. The load voltage level can be programmed up to the sixth place
after the decimal point.
b. The HIGH level load voltage MUST be higher than the LOW level load voltage
(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 voltage level is over the maximum rated specification, the
full scale voltage will be sent to the load module.
d. Engineering unit for load current is Volts.
e. Please refer to Appendices C, D and E for proper programming procedure of SL-
series electronic load modules.
Example:
CV:LOW 3.0 set LOW level load voltage to 3.0 V.
CV:HIGH 45.123456 set HIGH level load voltage to 45.123456 V.
