Fluke 433/434

Getting Started

PHASOR screen.

Shows phase relation between voltages and currents in a vector diagram. An example is the Scope Phasor screen:

1

3 2

Screen information:

cRMS values of the waveforms are displayed in the header.

dVector diagram. The vector of the reference phase A (L1) points to the positive X-direction.

eAdditional data such as fundamental phase voltages, frequency, and phase angles.

Function keys:

F1 Selection of data set to be displayed.

F3 Return to Scope Waveform screen.

F5 Switches between HOLD and RUN.

BAR GRAPH screen.

An example is the bar graph screen for Power Quality Monitoring. This screen gives a quick indication if important Power Quality parameters meet requirements.

Parameters include RMS voltages, Harmonics, Flicker, Rapid voltage changes, Dips, Swells, Interruptions, Unbalance, and Frequency.

The length of a bar increases if the related parameter is further away from its nominal value.

The bar graphs have a wide base (indicating a user definable percentage of the time that a parameter must be within specified levels: for instance 95 % of the readings over 10-minute observation periods must be within level) and a narrow top indicating the fixed 100% limit. If one of these limits is violated, the related bar changes from green to red. Dotted horizontal lines indicate both limits on the display.
