Monitoring Modes
The Xplorer provides nine monitoring modes of operation from which to
monitor and capture data relevant to the user’s application. Selecting any
setup category automatically sets trigger and capture conditions.
Advanced users are free to mix and match settings using the trigger
limits discussed in the next section.
The Xplorer allows you to monitor events in the following setup
categories:
Standard Power Quality (IEEE/IEC): Xplorer algorithms automatically
evaluate existing rms and waveform conditions to optimize setups to
reliably capture data. This feature ensures that the first-time user gets
the expected results, while providing the experienced user with the ability
to tweak settings for specific applications. Either way, the necessary data
used to identify critical events and optimize mitigation solutions is
recorded.
Current Inrush: Determining system characteristics during current
inrush conditions such as impedance changes during motor energization
or the I

t curve of a breaker trip is key to preventative maintenance and
enhanced power system performance. Inrush type events, such as motor
start-up, typically requires extended duration cycle-by-cycle recording.
With Xplorer, users can capture and store detailed data to evaluate
system performance against specifications and previous benchmark
data. Under the current inrush mode, triggers are typically current-based.
By operating in the inrush mode, the instrument will capture and store
highly detailed data in real time, then rearm and be ready to capture data
during the next test run.
Fault Recorder: A fault in a circuit is usually due to unintentional
grounding, a break in the line, a crossing or shorting of the wires, etc. A
digital fault recorder logs extended duration cycle-by-cycle recording.
Under the fault recorder mode, triggers are typically voltage-based. The
