B.77 STATus:OPEReration:ENABle? QUERY 
STAT:OPER:ENAB?
Syntax: Short Form: STAT:OPER:ENAB? Long Form: STATus:OPERation:ENABle?
Return Value: 0 to 1313 (1 + 32 + 256 + 1024).
Description: Reads Operation Enable Register (see Table B-2). Returns value of Operation Enable Register bits.
Bit set to 1 = function enabled (active, true); bit reset to 0 = function disabled (inactive, false). (See
example, Figure B-7.)
B.78 STATus:OPERation[:EVENt] QUERY 
STAT:OPER?
Syntax: Short Form: STAT:OPER[:EVEN]? Long Form: STATus:OPERation[:EVENt]?
Return Value: 0 to 1313 (1 + 32 + 256 + 1024).
Description: Indicates changes in conditions monitored by Operational Event Register. Returns the value of
the Operation Event register. The Operation Event register is a read-only register which holds
(latches) all events that occur. Reading the Operation Event register clears it. (See example, Figure B-
7.)
B.79 STATus:PRESet COMMAND 
STAT:PRES
Syntax: Short Form: STAT:PRES Long Form: STATus:PRESet
Description: Disables reporting of all status events. This command sets all bits of the Operation Condition (Table
B-2) and Questionable Condition Registers to 0, preventing all status events from being reported.
(See example, Figure B-7.)
FIGURE B-7. USING STATUS COMMANDS AND QUERIES
NOTE:The power supply is assumed to be operating in cV (constant voltage) mode.
STAT:OPER:ENAB 1056Mask enabled for CC, WTG and bits.
STAT:OPER:ENAB? Returns 1056 (32 + 1024) (CC, WTG bits set).
STAT:QUES:ENAB 3 Mask enabled for OV and OC bits (1 + 2).
STAT:QUES:ENAB? Returns 3 (1 + 2) indicating OV and OC bits are enabled.
STAT:PRES
Operation Condition and Questionable Condition registers are
reset.
INIT:CONT ON Continuous triggers enabled.
STAT:OPER:COND? Power supply returns 288 (256 + 32) to indicate that power
supply is constant voltage mode and Wait For Trigger is true.
STAT:OPER? Returns 1057, e.g., indicating that since the last reading of the
Operation Event Register the power supply has entered
Constant Current mode, the Wait Trigger was set.
STAT:OPER? Returns 0 indicating no changes since previous reading of the
Operation Event register.
STAT:QUES? Returns 0 (no questionable conditions occurred since previous
reading
--- (SHORT OUTPUT) OVERCURRENT CONDITION OCCURS
STAT:QUES? Returns 2 (overcurrent protection tripped since the last
STAT:QUES? query).
STAT:QUES:COND? Returns 2, (Power supply still in overcurrent protection state).
STAT:QUES?
Returns 0, (Register cleared by previous STAT:QUES?).
STAT:QUES:COND? Returns 2, (Power supply still in overcurrent protection state).
— (REMOVE SHORT FROM OUTPUT)
CURR:PROT:CLE Overcurrent condition cleared.
STAT:QUES:COND? Returns 0, (register cleared by CURR:PROT:CLE).
SYST:ERR?
Power supply returns 0,“No error” message.
