STATus:QUEStionable:CURRent:LEVel? <supply>[,MIN|MAX]
The STATus:QUEStionable:CURRent:LEVel? query returns a floating number
representing the last measurement of the power supply current in Amps.
Parameters
Returned Data
Comments
•
This command is not supported for all power supplies. When current
measurement is supported, the measurement returned is the last measurement
made on the supply identified with <param>. Under normal operation, this
should be within the last 2 seconds. Current is not measured during a *TST? or
CAL? operation, so a query to
STAT:QUES:CURR:LEV? will return the last
measurement made before the long operation was entered. If the power of the
mainframe is off, this query will return the last measurement made before
power turned off.
•
The optional MIN and MAX parameter allows the power supply’s current
limits to be queried. For Example,
STAT:QUES:CURR:LEV? P5,MAX
returns
the limit warning point for the 5V supply.
Error conditions
The following table lists the most common error conditions and causes. Error
numbers and corresponding messages can be found using
SYSTem:ERRor?
query.
Reset Condition
*RST does not affect the status system.
