Limited Warranty & Limitation of Liability

Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service. The warranty period is three years for the Analyzer and one year for its accessories. The warranty period begins on the date of shipment. Parts, product repairs and services are warranted for 90 days. This warranty extends only to the original buyer or end-user customer of a Fluke authorized reseller, and does not apply to fuses, disposable batteries or to any product which, in Fluke's opinion, has been misused, altered, neglected or damaged by accident or abnormal conditions of operation or handling. Fluke warrants that software will operate substantially in accordance with its functional specifications for 90 days and that it has been properly recorded on non-defective media. Fluke does not warrant that software will be error free or operate without interruption.

Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to extend a greater or different warranty on behalf of Fluke. Warranty support is available if product is purchased through a Fluke authorized sales outlet or Buyer has paid the applicable international price. Fluke reserves the right to invoice Buyer for importation costs of repair/replacement parts when product purchased in one country is submitted for repair in another country.

Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or replacement of a defective product which is returned to a Fluke authorized service center within the warranty period.

To obtain warranty service, contact your nearest Fluke authorized service center or send the product, with a description of the difficulty, postage and insurance prepaid (FOB Destination), to the nearest Fluke authorized service center. Fluke assumes no risk for damage in transit. Following warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that the failure was caused by misuse, alteration, accident or abnormal condition of operation or handling, Fluke will provide an estimate of repair costs and obtain authorization before commencing the work. Following repair, the product will be returned to the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).

THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, WHETHER ARISING FROM BREACH OF WARRANTY OR BASED ON CONTRACT, TORT, RELIANCE OR ANY OTHER THEORY.

Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or consequential damages, the limitations and exclusions of this warranty may not apply to every buyer. If any provision of this Warranty is held invalid or unenforceable by a court of competent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

Introduction and Safety Instructions

1.1 Introduction to Manual 1

1.1 Introduction to Manual

The Fluke 433, 434, 435 Three Phase Power Quality Analyzer (hereafter referred to as ‘Analyzer’) offers an extensive and powerful set of measurements to check power distribution systems. This Service Manual provides the information necessary to maintain the Analyzer at customer level.

The following information is presented in this Service Manual: Chapter 1. Introduction and safety Instructions. Read carefully before using or servicing

the Analyzer.

Chapter 2. Specifications. A complete set of detailed specifications. Chapter 3. Performance Verification. Chapter 4. Calibration Adjustment. Chapter 5. Disassembling the Analyzer. Chapter 6. List of Replaceable Parts.

Important. The Main PCA in this Analyzer is only available to Fluke Service Centers due to the programming that is necessary after installation.

1.2 Safety

1.2.1 Introduction

Read these pages carefully before beginning to install and use the Analyzer. The following paragraphs contain information, cautions and warnings which must be

followed to ensure safe operation and to keep the Analyzer in a safe condition.

Warning

Servicing described in this manual is to be done only by qualified service personnel. To avoid electrical shock, do not service the Analyzer unless you are qualified to do so.

1.2.2 Safety Precautions

For the correct and safe use of this Analyzer it is essential that both operating and service personnel follow generally accepted safety procedures in addition to the safety precautions specified in this manual. Specific warning and caution statements, where they apply, will be found throughout the manual. Where necessary, the warning and caution statements and/or symbols are marked on the Analyzer.

1.2.3 Caution and Warning Statements

Caution

Used to indicate correct operating or maintenance procedures to prevent damage to or destruction of the equipment or other property.

Warning

1.2.5 Impaired Safety

Whenever it is likely that safety has been impaired, the Analyzer must be turned off and disconnected from line power. The matter should then be referred to qualified technicians. Safety is likely to be impaired if, for example, the Analyzer fails to perform the intended measurements or shows visible damage.

Conformité Européenne

Warning

Removing the Analyzer covers or removing parts, except those to which access can be gained by hand, is likely to expose live parts and accessible terminals which can be dangerous to life.

The Analyzer shall be disconnected from all voltage sources before it is opened. Capacitors inside the Analyzer can hold their charge even if the Analyzer has been

separated from all voltage sources. When servicing the Analyzer, use only specified replacement parts.

2.1 Introduction

Performance Characteristics

Fluke guarantees the properties expressed in numerical values within the tolerances stated. Numerical values without tolerances are typical and represent the characteristics of an average instrument excluding accessories. The Analyzer meets the specified accuracy 30 minutes and two complete acquisitions after power-on. All operational specifications are valid under the restrictions mentioned in section ‘Environmental’ unless otherwise specified. Specifications are based on a one year calibration cycle.

Environmental Data

The environmental data mentioned in this manual are based on the results of the manufacturer’s verification procedures.

Safety Characteristics

The Analyzer has been designed and tested in accordance with standard EN61010-1 2 edition (2001), Safety Requirements for Electrical Equipment for Measurements Control and Laboratory Use for Class III Pollution Degree 2 instruments.

This manual contains information and warnings that must be followed by the user to ensure safe operation and to keep the Analyzer and its accessories in a safe condition. Use of this Analyzer and its accessories in a manner not specified by the manufacturer may impair the protection provided by the equipment.

The basic measurement time interval for parameters is a 10/12-cycle time interval for 50/60 Hz power systems. Measurement time interval aggregation is selected via the Logger averaging time setting. Note: 150/180 cycle (3 s) interval aggregation as per IEC 61000-4-30 Clauses A.7 can be selected from the SETUP, FUNCTION PREF, AGGREGation INTERVAL setting

Transient capture Captures waveform triggered on signal envelope. Additionally triggers on dips,

swells, interruptions and Amps level as specified by IEC61000-4-30

Inrush current The inrush current begins when the Arms half cycle rises above the inrush

threshold, and ends when the Arms half cycle rms is equal to or below the inrush threshold minus a user-selected hysteresis value. The measurement is the square root of the mean of the squared Arms half cycle values measured during the inrush duration. Each half-cycle interval is contiguous and nonoverlapping as recommended by IEC 61000-4-30. Markers indicate inrush duration. Cursors allow measurement of peak Arms half cycle.
