Once out of these limits a new event is recorded each time the RMS increases or decreases from previously recorded RMS by more than the specified sensitivity An Out of Limits event is also recorded when the RMS returns to within the specified limits This event is labeled NORMAL RMS events are recorded only for the channel which goes out of limits an RMS event on one main channel does not trigger an event on any other main channel Data reported by an RMS event may overlap with data reported by a waveform event a sag in voltage for example may be recorded as both a waveform event and a simultaneous RMS event This depends on the threshold settings for these two parameters Since RMS events occupy far less space in memory than waveform events it is usually good practice to set the wave threshold so that it does not trigger on relatively minor changes in voltage or current which can be recorded more efficiently by the High and Low limits thresholds The Out of Limits event illustrated below was recorded when the Voltage RMS went below the user set Low Limit of 116 0 volts Event 185 Channel A Setup 4 Fri Feb 9 1990 19 44 26 57 DRANETZ 658 Power Quality Analyzer QUT OF LIMITS 126 8 Yrms HIGH Limit 116 8 Yrms LOW Limit VOLTAGE Decreased Sens 3 8 Vrms to 6 2 Yrms 7685 66 f The first line of text on the screen indicates the event number the channel the event occurred on and the
