Inrush Studies
 Our Instrument Memory Recording Techniques
Conserve Memory and Guarantees Capture of
Lowest & Highest Signal Values per Storage
Interval.

 Recorder Captures up to 1000 Events Outside of
User Preset Limits And Logs Them With Duration In
Out-Of-Limits Log.
11
Stored Data:Event / Out of Limits Data
 Out of Limits- While recording, continuously monitors for
excedances of user defined limits for upper & lower V/I, subcycle (65uS), and THD.
• Monitors all connected channels, for analysis between load /
source side.

Waveform Capture
 Waveforms Are Captured Via:
•
•
•
•
Event Trigger
Time Trigger
THD/TDD/Individual Harmonic Trending
User Trigger from Front Panel
 User Specifies Number of Pre-Trigger Cycles
(Max 2) and Number of Post-Trigger Cycles To
Capture.
