5.1.4 Mains Disturbance Recording in Memory Mode Operation

If memory mode operation is started (see STORE menu function

above), further data in addition to those which appear at the dis-

play are saved to memory, allowing for computer aided visual

assessment:

• Regardless of which events occur, (DC+AC) TRMS voltage is

continuously recorded with adjustable sampling rate, and in

consideration of the selected hysteresis value.

• If a dip or a swell is recorded, the RMS half-cycle values of the

10 previous and 90 subsequent half-cycles are recorded.

• If a peak is recorded, the momentary values of the two half-

periods both before and after the peak are acquired.

Note

Memory mode operation must be stopped before data can

be read out of the instrument.
