Monitor - Power Quality Monitoring
Introduction
Power Quality Monitoring or System Monitor displays a Bar graph screen. This screen
shows whether important Power Quality parameters meet requirements. Parameters
include:
1. RMS voltages
2. Harmonics
3. Flicker
4. Dips/Interruptions/Rapid Voltage Changes/Swells (DIRS)
5. Unbalance/Frequency/Mains Signaling.
Monitor is started via a menu to select immediate or timed start of the measurement.
When selecting timed start, synchronisation with the 10 minute real time clock is used.
Timed start in combination with the optional GPS Synchronisation Unit GPS430 will
give Class A timing accuracy.
Figure 16-1 shows the bar graph screen and its properties.
Note: Monitor is not available for measurements in 400 Hz power systems such as
offered in Fluke 437-II.
