6.10. 400HZ OPERATION

The standard unit is also 400Hz enabled. The nominal frequency setting accepts up to 500Hz. Usual low
and high limits will apply without any special setting.
The measurement system of the unit allows frequencies up to 1000Hz to be measured precisely.
However the display is limited to 650Hz. Frequencies over 650Hz will be displayed as 650Hz.
The bandwidth of the harmonic analyzer is limited to 1800Hz. Thus in case of a 400Hz system, only the
rd
3 harmonic will be displayed.
The waveform display of a 400Hz signal will be represented with 10 points. It will not be as accurate as
50/60Hz signals.
