Mains Disturbance Recording In Memory Mode Operation - Gossen MetraWatt METRAHIT ENERGY TRMS System Multimeter Operating Instructions Manual

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.
