Introduction

The Analyzer offers an extensive and powerful set of measurements to check power
distribution systems. Some give a general impression of power system performance.
Others are used to investigate specific details. This chapter gives an overview on how to
perform measurements in a logical order.
The measuring modes are described in detail in Chapter 7 to 22. Each measuring mode is
explained in a separate chapter.
Refer to Chapter 27 Specifications for an overview of the parameters that are measured in
each measuring mode and their accuracies.

Wave, Mains Signaling, Wave Event, Rms Event, and 0.1 % voltage input accuracy.
Moreover Fluke 437-II has additional features such as Shipboard V/A/Hz and the
possibility to measure in 400 Hz power systems, and has a heavy duty Hard Case
with rollers.
In Fluke 434-II the functions Flicker, Transients, Power Wave and Mains Signaling

General Measurements

To check if voltage leads and current clamps are connected correctly, use Scope
Waveform and Scope Phasor. The clamps are marked with an arrow to facilitate proper
signal polarity. Chapter 6 Input Connections explains how to make connections.

Features of Fluke 434-II/435-II/437-II

After you have switched on a certain measurement, a settling time of about
10 seconds will pass before the measurement is started. During this time
the U (Unstable) symbol shows in the screen header. Moreover the timer
counts down from –10 seconds. A measurement has no unstable period
when used with a timed start.
