Scope Waveform and Phasor

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 (12 or 10 cycle rms acc. to IEC61000-4-30). 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:

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.
