Features Of Fluke 434/435
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 18. Each measuring mode is explained in a separate chapter.
Fluke 435 has additional features such as Mains Signaling, Logging, 0.1 % voltage input accuracy acc. to IEC61000-4-30 2003 Class A, extra memory to store Logging Data, Power Log software, flexible current clamps, and a heavy duty trolley style case.
In Fluke 434 the functions Mains Signaling and Logging can be installed optionally. If not installed, they show up in the menu in grey color.
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.
To get a general impression of the quality of a power system use MONITOR. The MONITOR key displays a screen with Bar Graphs that show quality aspects of the phase voltages. A Bar Graph changes from green to red if the related aspect does not meet the limits. Up to 7 different sets of limits can be chosen for Fluke 435: a number of them are user programmable. One of these sets are the limits according to the EN50160 norm. For each quality aspect submenus with detailed information are attainable via the function keys F1 ... F5.
Numerical data is shown by Volts/Amps/Hertz. For this press the MENU key. Then select Volts/Amps/Hertz and press F5 – OK to display a Meter screen with the present values of voltages (rms and peak), currents (rms and peak), frequency and Crest Factors per phase. Press F5 – TREND so display the course over time of these values.
3-1
Fluke 434/435
Users Manual
Measuring modes to investigate details
Phase voltages. Should be close to the nominal value. Voltage waveforms must be a sine wave that is smooth and free from distortion. Use Scope Waveform to check the waveform shape. Use Dips & Swells to record sudden voltage changes. Use Transients mode to capture voltage anomalies.
Phase currents. Use Volts/Amps/Hertz and Dips & Swells to check current/voltage relations. Use Inrush Current to record sudden current increases like motor inrush.
Crest Factor. A CF of 1.8 or higher means high waveform distortion. Use Scope Waveform to see waveform distortion. Use Harmonics mode to identify harmonics and THD (Total Harmonic Distortion).
Harmonics. Use Harmonics mode to check for voltage and current harmonics and THD per phase. Use Trend to record harmonics over time.
Flicker. Use Flicker to check short and long term voltage flicker and related data per phase. Use Trend to record these values over time.
Dips & Swells. Use Dips & Swells to record sudden voltage changes as short as half a cycle.
Frequency. Should be close to nominal value. Frequency is normally very stable. Select Volts/Amps/Hertz to display frequency. The course of frequency over time is recorded in the Trend screen.
Unbalance. Each phase voltage should not differ more than 1 % from the average of the three. Current unbalance should not exceed 10 %. Use Scope Phasor or Unbalance mode to investigate unbalances.
Mains Signaling. Can be used to analyze the level of remote control signals that often are present on power distribution systems.
Logger. Allows you to store multiple readings with high resolution in a long memory.

Figure 4-2. Fixing the hang strap
Powering the Analyzer
The Analyzer has a built-in rechargeable NiMH battery that can power it for more than 6 hours when fully charged. When powered by the battery, the battery condition symbol in the screen header indicates the charge condition. This symbol ranges from fully charged to empty: 
.
When empty allow the batteries to fully charge with the Battery Charger/Power Adapter model BC430. A full charge takes at least 4 hours with the Analyzer turned off. When turned-on charging takes much longer.
No damage will occur if the charger is connected for long periods, e.g. over the weekend. The Analyzer automatically switches to trickle charging. At delivery the battery may be empty and it is recommended to charge it before use.
Concerning the use of the Battery Charger/Power Adapter bear the following in mind:
•Use only the supplied Battery Charger/Power Adapter model BC430.
•Before use check that the BC430 voltage and frequency match the local line power range.
If necessary set the slider switch of BC430 to the correct voltage.
•Connect the Battery Charger to the ac outlet.
•Connect the battery charger to the POWER ADAPTER input on the top side of the Analyzer.
•To avoid overheating of the battery during charging, do not exceed the allowable ambient temperature as given in the specifications.

Phase Colors
Measuring results belonging to different phases are presented with individual colors. If - for a certain phase - voltage and current are displayed simultaneously, the voltage color has a dark tone and the current has a light tone. The set of phase colors can be chosen via the SETUP key and function key F4 – USER PREF. For detailed information see Chapter 20.
Screen Types
Below you will find a brief description of each screen type and its purpose. The measuring mode it is used for is given as well as the manual chapter with detailed information. Bear in mind that the amount of screen information depends on the number of phases and the wiring configuration. Refer to Figure 5-1, item 1 ... 5.
1Meter screen: gives an instantaneous overview of a big number of important numerical measuring values. Used for: Volts/Amps/Hertz (Chapter 8), Dips & Swells (Chapter 9), Harmonics (Chapter 10), Power & Energy (Chapter 11), Flicker (Chapter 12), Unbalance (Chapter 13), and Power Quality Monitoring (Chapter 18).
2Trend screen: this type of screen is related to a Meter screen. Trend shows the course over time of measuring values from the Meter screen.

Input Connections
Introduction
This chapter explains how to make connection to the power distribution system under test and how to adjust the Analyzer settings.
Check that the Analyzer setup meets the characteristics of the system under test and the accessories that are used. This concerns:
•wiring configuration
•nominal frequency
•nominal voltage
•properties of voltage leads and current clamps
The actual setup is shown in the welcome screen that appears after power up. To change the setup, refer to Chapter 20.
Input Connections
The Analyzer has 4 BNC-inputs for current clamps and 5 banana-inputs for voltages.
Self-adhesive decals are supplied corresponding to wiring color codes used in the USA, Canada, Continental Europe, the UK, and China. Stick the decals that fit to your local wiring codes around the current and voltage inputs as shown in Figure 6-1.

Figure 6-1. Mounting the decals for voltage and current inputs
De-energize power systems before making connections whenever possible. Always use appropriate equipment for personal protection. Avoid working alone and work according to the warnings listed in Chapter 1, Safety Information.
For a 3-phase system make the connections as shown in Figure 6-2.
Figure 6-2. Connection of Analyzer to 3-phase distribution system
First put the current clamps around the conductors of phase A (L1), B (L2), C (L3), and N(eutral). The clamps are marked with an arrow indicating the correct signal polarity.
Next make the voltage connections: start with Ground and then in succession N, A (L1), B (L2), and C (L3). For correct measuring results, always connect the Ground input. Always double-check the connections. Make sure that current clamps are secured and completely closed around the conductors.
For single phase measurements, use current input A (L1) and the voltage inputs Ground, N(eutral), and phase A (L1).
A (L1) is the reference phase for all measurements.

Before making any measurements, set the Analyzer up for the line voltage, frequency, and wiring configuration of the power system you want to measure. This is explained in Chapter 20, General Settings.
Scope Waveform and Phasor display are useful to check if voltage leads and current clamps are connected correctly. In the vector diagram the phase voltages and currents A (L1), B (L2), and C (L3) should appear in sequence when observing them in clockwise direction as shown in the example in Figure 6-3 (This type of vector diagram is displayed after reset of the Analyzer to factory defaults as explained on page 4-4).
