4.5 INSTRUMENT FUNCTIONS
4.5.1 Measurements
There are 4 possible real-time modes: waveform
, harmonics
, power
, and energy
There are 5 possible recording modes: trend
, transients
, inrush
currents
, alarms
, and network monitoring
1.
Ensure that the instrument’s configuration is correct for the desired
measurements.
2. Then, you can make the following measurements:
• View a signal’s waveforms
• View a signal’s harmonics
• View power measurements
• Meter energy
• Record a trend
• Record transients
• Capture an inrush current
• Detect alarms
• Monitor a network
Some functions cannot be run simultaneously:
■
The real-time modes (waveform, harmonics, power, and energy) can be
activated while recordings are in progress
■
If an inrush current capture is in progress, you cannot start the recording of
a trend, transients, alarms, or monitoring
■
If a recording of a trend, transients, alarms, or monitoring is in progress, you
cannot start an inrush current capture
