Remote Programming Sorensen SLH-Series DC High Power Electronic Load
dynamic range, these ranges are adjusted by the load module automatically which
depends on the programmed Tlow / Thigh range.
Example:
PERI:LOW 0.125;PERI:HIGH 0.8
Set the LOW dynamic load duration to 0.125 ms, and the HIGH dynamic load duration to 0.8 ms.
RISE Time
Purpose:
RISE load current slew rate setting.
Command Syntax:
RISE{SP}{NR2}{NL}
Description:
The RISE load current slew rate of load level change or dynamic load can be programmed by RISE
command. The RISE slew rate of SLH-series DC electronic load modules can be fully independent
from the FALL slew rate.
The RISE load current slew rate data must include a decimal point, otherwise this command is will
not execute.
The value for the RISE load current slew rate can be programmed up to sixth place after the
decimal point. If the programming load current level is over the maximum specification at the
programmed range of SLH DC series load module, the fastest RISE slew rate will be sent to the
load module. Please verify the Range 1/2 command before execute the load RISE slew rate setting
command, otherwise the SLH DC load module will adjust to fit the RISE slew rate after
programming the RISE command. The engineering unit for RISE slew rate is “A/us."
Example:
RISE 1.25 set RISE slew rate to 1.25 A/us.
FALL Time
Purpose:
FALL load current slew rate setting.
Command Syntax:
FALL{SP}{NR2}{NL}
Description:
Programs the FALL load current slew rate of load level change or dynamic load. The FALL slew
rate of SLH DC electronic load modules can be fully independent of the RISE slew rate.
The FALL load current slew rate data must include a decimal point, otherwise this command will not
execute. The value for FALL load current slew rate can be programmed up to the sixth place after
the decimal point. If the programming load FALL slew rate is over the full-scale specification, the
fastest FALL slew rate will be sent to the load module. Please verify the Range 1/2 command
before executing the load FALL slew rate setting command, otherwise, the load module will adjust
to fit the FALL slew rate after programming the FALL command.
The engineering unit for FALL slew rate is “A/
μs”.
Example:
FALL 0.124 set FALL slew rate to 0.124 A/
μs.
