You can query the current value of most parameters by adding a
question mark ( ? ) to the command. For example, the following
command sets the sample count to 10 readings:
"SAMP:COUN 10"
You can query the sample count by executing:
"SAMP:COUN?"
You can also query the minimum or maximum count allowed as follows:
"SAMP:COUN? MIN"
"SAMP:COUN? MAX"
※
Note: If you send two query commands without reading the response
from the first, and then attempt to read the second response, you may
receive some data from the first response followed by the complete
second response. To avoid this, do not send a query command without
reading the response. When you cannot avoid this situation, send a
device clear before sending the second query command.
SCPI Command Terminators
A command string sent to the multimeter must terminate with a <new
line> character. The IEEE-488 EOI (end-or-identify) message is
interpreted as a <new line> character and can be used to terminate a
command string in place of a <new line> character. A <carriage return>
followed by a <new line> is also accepted. Command string termination
will always reset the current SCPI command path to the root level.
IEEE-488.2 Common Commands
The IEEE-488.2 standard defines a set of common commands that
perform functions like reset, self-test, and status operations. Common
commands always begin with an asterisk ( * ), are four to five characters
