8 Measuring process
The power analyzer is designed for the measuring of currents and
voltages through up to three different channels. It calculates rms
values, real, apparent and idle power and other derived values.
The accuracy is thereby not affected by the wave form, frequency
or phase shift. Harmonics are output to maximum half the
sampling frequency.
You have the option to apply the default settings or a user-defined
configuration. If you wish to use a user-defined configuration, you
must first define and save the respective settings and then load the
relevant configuration (see chapter 7: "Configuration", page 22).
The power analyzer begins to measure as soon as the measuring
arrangement is set up and the device is switched on.
8.1 Prior to measuring
Connect power analyzer to the mains socket.
Check the measuring connections at the power analyzer.
Switch on the power analyzer.
If you want to complete an analysis using the default configuration,
no additional steps are required.
Ensure that the factory configuration
is loaded (see chapter
7.2: "Load configuration", page 23).
If you want to complete an analysis using a user-defined
configuration, load the respective configuration see chapter 7
"Configuration", page 22).
Important
If you want to measure with external shunt or probe please make
sure that there is no signal connected at the direct current inputs.
Signals on both inputs (external- and direct current input) can
damage the measurement unit.
