OPALL <
NRF
>
Simultaneously sets all outputs on/off where <
NRF
> has the following meaning:
0=All OFF, 1=ALL ON.
If OPALL sets all outputs ON then any that were already on will remain ON.
If OPALL sets all outputs OFF then any that were already off will remain OFF

MODE <
NRF
>
Set the instrument operating mode to LINK or assign control to output 1 or 2
<
NRF
> has the following meaning:
0 = linked, 1 = assign control to output 1, 2 = assign control to output 2.
Setting linked mode uniquely affects the way the instrument responds to some
remote commands. Commands to set Range, Voltage, Current Limit, OVP or
OCP sent to either Output 1 or Output 2 will change the setting on both outputs
simultaneously. Similarly, increment/decrement commands sent to either Main
output will step V or I on both outputs; however, the step size will be that set for
the individual output. Assigning control to outputs 1 or 2 exits linked mode but
has no other affect until the instrument is returned to local operation.
Any operating mode set in remote operation will be retained when the
instrument is returned to local operation.

If the instrument is operating in linked mode then the entire instrument set-up
(excluding auxiliary output) will be stored in the linked mode set-up store
specified by <
NRF

If the instrument is operating in LINK mode then the entire instrument set-up
(excluding AUX output) will be recalled from the LINK mode set-up store
specified by <

System and Status Commands
*RST
Resets the instrument to the factory default settings
−
(see Factory Defaults
section) with the exception of all remote interface settings.
EER?
Query and clear Execution Error Register. The response format is nr1<
RMT
>.
QER?
Query and clear Query Error Register. The response format is nr1<
RMT
>
*CLS
Clear Status. Clears the Standard Event Status Register, Query Error Register
and Execution Error Register. This indirectly clears the Status Byte Register.
