This Article is about: The Fluke-1773, Fluke-1775 and Fluke-1777 PQ Meter mode vs PQ Logger mode.
The PQ Meter mode and PQ Logger function record Volts, Amps, Hz, Unbalance Volts and Amps, Watts, VA, VAR, PF, DPF, Wh, VAh, VArH, Voltage, Current, Power Harmonics THD 1st thru 50th and Events.
The PQ Meter mode has a limit of 24 hours when creating 1 second Trend Data, the mode will continue past 24 hours and keep gathering Events, but the Trend Data will only be available for the last 24 hours.
The PQ Logger mode allows you to manage the Event Trigger settings, Session settings to set the Duration, Trend Interval and Harmonic settings. You can create Logging session for more than 24 hours and more than 30 days if required.
- Fluke-1773 Event capturing includes Dips, Swells, Interruptions, Rapid Voltage Change, Main Signaling, Waveshape Deviation and Inrush Current. The Event data is limited to a Table with Date, Time, Type and Duration, Level, Phase and Severity of the Event. See below example.
- Fluke-1775 Event capturing includes Dips, Swells, Interruptions, Rapid Voltage Change, Main Signaling, Waveshape Deviation, Transients (1MHz) and Inrush Current. The Event Data consist of the Table and Event Graph that includes RMS Profile and Waveshape data.
- Fluke-1777 Event capturing is the same as the Fluke-1775 except it has two choices the user needs to select during the setup for capturing Transients (1MHz or 20MHz). Below is an example of the Table, Event Graph with RMS Profile and Waveshape data.
