For example, if you want to read out the values for Urms, Irms, and P, send the "NUMERIC:NORMAL:VALUE?" command. The reply would be 3 data outputs as shown below.
The output items, using the "NUMERIC:NORMAL:ITEM" command, of Urms, Irms, and P are set to the 1st, 2nd, and 3rd data respectively. The first data is Urms=4.083E+00, the second data is Irms=50.002E+00, and the last data is P=202.65E+00 for element 1.
In the above procedure using "NUMERIC:NORMAL:ITEM" you set each output item individually, but you can also specify all output items at once using a preset pattern. There are 4 preset patterns that can be used. For example, to use preset pattern, send the "NUMERIC:NORMAL:PRESET1" command to the measuring instrument.
You can also use preset pattern 1 to output Urms, Irms, and P by sending the following 4 commands in order to the measuring instrument.
When using a preset and there are a large number of items to be output, first, choose the closest preset pattern, then add a "NUMERIC:NORMAL:ITEM" command for each remaining item.
For more information on preset output item patterns, please refer to the following manuals:
