*SAV Save Command
Type
Device State
Description
This command stores the present state of the single electronic load and the states of all
channels of the multiple electronic load in a specified location in memory. Location 0 is 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. If no state has been saved to location 0,
then it will still contain the factory-default state (refer to “Factory Default Settings” in the
Operating Manual of the electronic load model that you are programming). States stored in
locations 1 through 6 are lost whenever power is cycled.
Note
To restore the factory-default state to Location 0, execute *RST;*SAV 0
The parameters stored by *SAV are identical to those affected by *RST except that the
following states are not stored:
■ CAL:MODE ON|OFF (Refer to the electronic load; Operating Manual).
■ CHAN.
Note
*SAV also does not store the states of Status Enable registers or Transition Filters.

Device Interface
Description
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. See Chapter 5 - Status Reporting
for more details concerning the Status Byte register.
