SLM-Series AC/DC Electronic Load GPIB/RS-232 Programming Operation
M540072-01 Rev B 4-11
LOAD OFF VOLTAGE Setting
Purpose:
The Load OFF voltage setting (Initial is 0.5V) of DC electronic load modules.
Command Syntax:
SLM DC, SLD Modules:
LDOF{SP}{NR2}{;|NL}
Description:
The Load Off voltage can be adjusted by the LDOF command; the adjust Range 1s 0.1-load
on voltage (Res. = 0.1V. The load will stop to sink current if power source output voltage is
lower than Load Off voltage.
Example:
LDOF 2.0 ; Set the Load Off voltage to 2.0V. The load will start to sink current when power
source output voltage is lower than 2.0V.
LEVEL HIGH/LOW
Purpose:
Select Low or High level in static mode, of DC electronic loads, or LEVEL A/B of AC
electronic loads.
Command Syntax:
All Modules:
[GLOB:] LEVE {SP}{HIGH|LOW}{NL}
Description:
LEVE LOW is Set LOW current level in CC mode, LOW resistance level in CR mode, or
LOW voltage level in CV mode at the active load channel.
LEVE 1 is Set HIGH current level in CC mode, HIGH resistance level in CR mode, or HIGH
voltage level in CV mode at the active load channel.
PRESET ON/OFF
Purpose:
Set the upper or lower digit multi-function meter to display the programming load level.
Command Syntax:
All Modules:
[GLOB:]PRES{SP}{0|1|OFF|ON}{NL}
Description:
GLOB:PRES ON is set all the load module in the SLM chassis to preset on status.
MODE
Purpose:
Select the operating mode of Electronic load module.
Command Syntax:
All Modules:
[GLOB:]MODE{SP}{0|1|2|3|CC|CR|CV|CP}{NL}
Description:
GLOB:MODE CC ; set the presently operating mode to Constant Current mode for all load
module in the SLM chassis.
MODE CV ; set the presently operating mode to Constant Voltage mode.
MODE 1 ; set the presently operating mode to Constant Resistance mode.
MODE CP ; set the presently operation mode to Constant Power mode.
Note:
MODE CV is available in DC loads only.
MODE CP is available in DC, single input loads only.
