Scope Waveform And Phasor; Introduction; Scope Waveform - Fluke 434 User Manual

Introduction

Scope mode shows voltages and currents in the power system under test by means of
waveforms or vector diagram. Also numerical values are shown such as phase voltages,
phase currents, frequency, and phase angles between voltages and currents.

Scope Waveform

To access the Scope Waveform screen:
SCOPE
The Scope Waveform screen offers an oscilloscope style of display of voltage and/or
current waveforms with a fast update rate. The screen header shows the related rms
voltage/current values (10/12 cycle rms or 150/180 cycle rms as per IEC61000-4-
30:2003). As a default 2 waveform periods are displayed. Channel A (L1) is the reference
channel and 2 complete cycles starting at 0 volt are displayed.
Available function keys:
F1
F2
F3

Scope Waveform and Phasor

Selection of waveform set to be displayed: V displays all
voltages, A displays all currents. A (L1), B (L2), C (L3), N
(neutral) give simultaneous display of phase voltage and
current for the selected phase.
Access to submenu for Cursor and Zoom operation.
Access to the Phasor screen. For description see below.
