*SAV
This command stores the present state of the electronic load to a specified location in memory. Up to 10
states can be stored. States in saved in locations 1-6 are volatile, the data will be lost when power is
turned off. States in locations 0, 7, 8, and 9 are nonvolatile, the data will be saved when power is
removed. If a particular state is desired at power-on, it should be stored in location 0. It then will be
recalled at power-on if the power-on state is set to RCL0. Use *RCL to retrieve instrument states. Any
lists associated with a device state are also saved if they are stored in locations 0, 7, 8, or 9.
*SAV does not save the programmed trigger values ([SOURce:]CURRent:TRIGGer,
NOTE:
[SOURce:]RESistance:TRIGGer, [SOURce:]VOLTage:TRIGGer). Programming an *RCL
or a *RST command causes the triggered settings to revert to their [IMMediate] settings.

*SRE
This command sets the condition of the Service Request Enable Register. This register determines which
bits from the Status Byte Register (see *STB for its bit configuration) are allowed to set the Master Status
Summary (MSS) bit and the Request for Service (RQS) summary bit. A 1 in any Service Request Enable
Register bit position enables the corresponding Status Byte Register bit and all such enabled bits then
are logically ORed to cause Bit 6 of the Status Byte Register to be set.
When the controller conducts a serial poll in response to SRQ, the RQS bit is cleared, but the MSS bit is
not. When *SRE is cleared (by programming it with 0), the electronic load cannot generate an SRQ to the
controller. The query returns the current state of *SRE.

*STB?
This query reads the Status Byte register, which contains the status summary bits and the Output Queue
MAV bit. Reading the Status Byte register does not clear it. The input summary bits are cleared when
the appropriate event registers are read (see chapter 3 under "Programming the Status Registers" for
more information). A serial poll also returns the value of the Status Byte register, except that bit 6 returns
Request for Service (RQS) instead of Master Status Summary (MSS). A serial poll clears RQS, but not
MSS. When MSS is set, it indicates that the electronic load has one or more reasons for requesting
service.
