*PSC Power-on Status Clear Command/Query
Type
Device Initialization
Description
This command controls the automatic clearing at power turn-on of:
•
The Service Request Enable register.
•
The Standard Event Status Enable register.
If the command parameter = 0, then the electronic load can be programmed to request
service at turn on. Any non-zero parameter causes both registers to be cleared at turn on,
preventing the electronic load from being capable of requesting service at this time. See
Chapter 5 - Status Reporting for details of these registers.

*RCL Recall Instrument State Command
Type
Device State
Description
This command restores the electronic load to a state that was previously stored in memory
with a *SAV command to the specified location (see *SAV). *RCL also does the
following:
■ Forces an ABORt command before resetting any parameters. (This removes all
pending trigger levels.)
■ After all parameters have been recalled, executes an INP:PROT:CLE to clear the
electronic load’s protection circuits.
■ Sets CAL:MODE to OFF (See the electronic load Operating Manual for the
calibration commands).
■ Sets CHAN to 1 in the multiple electronic load.
At power turn-on, the equivalent of an *RCL 0 is executed to restore the electronic load to
the state stored in location 0. The same state is also set if the *RCL command is directed
to a location where no state was stored since the last time power was cycled.
Note
*RCL does not affect any Status Enable registers or Transition Filters.
