TRMS values of voltage and current, the power and derived values are measured via the
power measuring channels.
•
prCE harmonics mode
In this mode the LMG450 works as an harmonic analyser. All measurements are judged
according to the standards. There is only a minimum of settings to prevent set-up errors.
This mode can only be used for precompliance measurings.
•
CE flicker mode
In this mode the LMG450 works as a full compliance flicker meter. All measurements are
judged according to the standards. There is only a minimum of settings to prevent set-up
errors.
•
Harm100 mode
In this mode the LMG450 works as an harmonic analyser for 100 harmonic components.
You get many values like phase angles and the power at each frequency.
•
Transient mode
In this mode the LMG450 works as a transient recorder. You can define special events
when the storage of values should be triggered.
The active mode depends on the setting in the Measuring menu. Some other menus also
depend on this setting (see the respective description).
For each measuring mode you find a chapter in the manual. Inside this chapter the different
menus for this operating mode are described.
