Command Setup
To define the Command Setup, set a command or a function to the Command field,
and enter the command parameters to the Argument field. Also, be aware of the
following note.
• FMT command’s first parameter must be 13.
• Use the Unit value of Channel Setup to specify the channel.
• Use the ReadDataBuffer function to read measurement data.
• P
rogram memory number must be within the range of 1 to 1000.
• SCR command parameter cannot be abbreviated.
• VAR command’s second parameter must be within the range of 1 to 40. Hence,
inter
nal variables
%I1 to %I40 and %R1 to %R40 are available.
A setup example is shown in Table 5-2. This example uses SM
U1 to performs
voltage output and current spot measurement.
