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:
The PZ4000 is designed for High Frequency Power Measurements as well as Transient Power Measurements. Its real-time acquisition system can perform cycle-by-cycle power measurements. One to Four input elements offer Basic Power Accuracy of 0.2% with 2 MHz Bandwidth and 5MS/sec digitizing rates.
The High-end WT1600 is designed for a wide range of applications, from energy-saving to large load applications. The WT1600 has a six element input capability to provide maximum flexibility, and Basic Power Accuracy of 0.1% with 1 MHz Bandwidth.
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.
