If you send "MEASURE:VALUE?" and read out the measured data, 3 data are output as shown in the following example:
Example Output: 4.083E+00,50.002E+00,202.65E+00
"Output Format for Normal Measurement Mode," shows that the order of data output is: V1, A1, W1 etc. Therefore in the example, the first data is V1=4.083E+00, the second data is A1=50.002E+00, and the last data is W1=202.65E+00.
In the "MEASURE:ITEM:NORMAL:PRESET XXX" communications command which was sent first, ALL, DEFAULT1, and DEFAULT2 are available in addition to CLEAR, so you can output only the specified items of the measured values. Also, for example, if you want to output the VA item in addition to "DEFAULT1," you can send "MEASURE:ITEM:NORMAL:PRESET DEFAULT1", then send "MEASURE:ITEM:NORMAL:VA:ELEMENT1 ON" to add it to the DEFAULT1 item. On the other hand, if you want to remove W on element 1 from the "DEFAULT1" setting item, you can send "MEASURE:ITEM:NORMAL:PRESET DEFAULT1", then send "MEASURE:ITEM:NORMAL:W:ELEMENT1 OFF." In this way you can specify individual items for output by adding output items to or taking output items away from the CLEAR, ALL, DEFAULT1, and DEFAULT2 preset settings.

The WT2000 digital powermeter series has been designed with emphasis on basic performance (bandwidth, accuracy, response speed, and noise immunity) from the viewpoint of measurement of electrical quantities. The broad range of functions of these power analyzers enable them to be used in various fields of applications.
Measure characteristics of devices that generate, transform or consume electricity. Also called power meters or wattmeters, these devices measure parameters such as true power (watts), power factor, harmonics, and efficiency.
