Querying Parameter Settings
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"
C a u t i o n 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.
