2. Read the Event Register for all currents:
STAT:QUES:CURR?
The system response: 0
3. Read the Condition Register for all currents:
STAT:QUES:CURR:COND?
The system response: 0
4. Set an alarm to activate by dropping the amperage threshold for the +5 Volt
supply down to 10 Amps:
STAT:QUES:CURR:LIMIT P5, 10.0
The system response: The front panel display should start flashing the alarm
for +5V current over limits
5. Read the Condition and Event Registers. They should have bit 2 set.
STAT:QUES:CURR?
The system response: 4
STAT:QUES:CURR:CONDITION:
The system response: 4
6. Read the same registers: since the event still exists the Condition Register
will display the problem with +5V current. The Event Register was cleared
from the previous read operation:
STAT:QUES:CURR?
The system response: 0
STAT:QUES:CURR:COND?
The system response: 4
7. Clear all event registers and reset the alarm:
*CLS
8. Read the Event Register that shows *CLS caused the event to be
re-triggered:
STAT:QUES:CURR?
The system response: 4
9. Clear the event again to trigger the event, but this time eliminate the error
before reading registers:
*CLS
STAT:QUES:CURR:LIMIT P5, MAX
The system response: The alarm is removed
STAT:QUES:CURR?
The system response: 4 (Error situation removed, but still displays the event)
STAT:QUES:CURR:COND?
The system response: 0 (No errors exist at this time)
