*RST
Reset Command. This command resets the electronic load to a pre-defined state stored in profile 0.
It is similar to “*RCL 0” command except the following:
*RST also does the following:
Ϯ Forces an ABORt command before resetting any parameters.
Ϯ After
all parameters have been reset, executes an INP:PROT:CLE to clear the
electronic load’s protection circuits.
Note *RST does not affect any Status Enable registers or Transition Filters.
Command Syntax *RST
Parameters None
*SAV
Save Command. This command stores the present state of the electronic load in a specified
location in memory. Location 0, 1, 2 , and 3 are in nonvolatile memory and retains its state throughout
power cycling. The electronic load will be set to the state in location 0 at power turn-on.
Command Syntax *SAV
Parameters 0 to 3
Suffix None
*SRE
Service Request Enable Command/Query. This command sets the condition of the Service
Request Enable register, which determines which events of the Status Byte register (see *STB) are
allowed to set the MSS (Master Status Summary) bit. A “1” in the bit position enables the
corresponding Status Byte bit to set the MSS bit. All the enabled bits are logically ORed to cause Bit 6
(the Master Summary Status Bit) of the Status Byte register to be set.
Command Syntax *SRE
Parameters 0 to 255
Suffix None
Query Syntax *SRE?
Returned Parameters , Value: 0 to 255
Suffix None
*STB?
Read Status Byte Query. This query reads the Status Byte register. Note that the MSS (Master
Summary Status) bit and not the RQS bit is returned in Bit 6. This bit indicates whether or not the
electronic load has at least one reason for requesting service. *STB? does not clear the Status Byte
register, which is cleared only when subsequent action has cleared all its set bits.
