LIMITED WARRANTY AND 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 two years and 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, contaminated, 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 only 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 to obtain return authorization information, then send the product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). 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 failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition of operation or handling, including overvoltage failures caused by use outside the product’s specified rating, or normal wear and tear of mechanical components, 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, ARISING FROM ANY CAUSE OR 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 or other decision-maker of competent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

BEGRENZTE GEWÄHRLEISTUNG UND HAFTUNGSBESCHRÄNKUNG

Fluke gewährleistet, daß jedes Fluke-Produkt unter normalem Gebrauch und Service frei von Material- und Fertigungsdefekten ist. Die Garantiedauer beträgt 2 Jahre ab Versanddatum. Die Garantiedauer für Teile, Produktreparaturen und Service beträgt 90 Tage. Diese Garantie wird ausschließlich dem Ersterwerber bzw. dem Endverbraucher geleistet, der das betreffende Produkt von einer von Fluke autorisierten Verkaufsstelle erworben hat, und erstreckt sich nicht auf Sicherungen, Einwegbatterien oder andere Produkte, die nach dem Ermessen von Fluke unsachgemäß verwendet, verändert, verschmutzt, vernachlässigt, durch Unfälle beschädigt oder abnormalen Betriebsbedingungen oder einer unsachgemäßen Handhabung ausgesetzt wurden. Fluke garantiert für einen Zeitraum von 90 Tagen, daß die Software im wesentlichen in Übereinstimmung mit den einschlägigen Funktionsbeschreibungen funktioniert und daß diese Software auf fehlerfreien Datenträgern gespeichert wurde. Fluke übernimmt jedoch keine Garantie dafür, daß die Software fehlerfrei ist und störungsfrei arbeitet.

Von Fluke autorisierte Verkaufsstellen werden diese Garantie ausschließlich für neue und nicht benutzte, an Endverbraucher verkaufte Produkte leisten. Die Verkaufsstellen sind jedoch nicht dazu berechtigt, diese Garantie im Namen von Fluke zu verlängern, auszudehnen oder in irgendeiner anderen Weise abzuändern. Der Erwerber hat nur dann das Recht, aus der Garantie abgeleitete Unterstützungsleistungen in Anspruch zu nehmen, wenn er das Produkt bei einer von Fluke autorisierten Vertriebsstelle gekauft oder den jeweils geltenden internationalen Preis gezahlt hat. Fluke behält sich das Recht vor, dem Erwerber Einfuhrgebühren für Ersatzteile in Rechnung zu stellen, wenn dieser das Produkt in einem anderen Land zur Reparatur anbietet, als dem Land, in dem er das Produkt ursprünglich erworben hat.

Flukes Garantieverpflichtung beschränkt sich darauf, daß Fluke nach eigenem Ermessen den Kaufpreis ersetzt oder aber das defekte Produkt unentgeltlich repariert oder austauscht, wenn dieses Produkt innerhalb der Garantiefrist einem von Fluke autorisierten Servicezentrum zur Reparatur übergeben wird.

Um die Garantieleistung in Anspruch zu nehmen, wenden Sie sich bitte an das nächstgelegene und von Fluke autorisierte Servicezentrum, um Rücknahmeinformationen zu erhalten, und senden Sie dann das Produkt mit einer Beschreibung des Problems und unter Vorauszahlung von Fracht- und Versicherungskosten (FOB Bestimmungsort) an das nächstgelegene und von Fluke autorisierte Servicezentrum. Fluke übernimmt keine Haftung für Transportschäden. Im Anschluß an die Reparatur wird das Produkt unter Vorauszahlung von Frachtkosten (FOB Bestimmungsort) an den Erwerber zurückgesandt.Wenn Fluke jedoch feststellt, daß der Defekt auf Vernachlässigung, unsachgemäße Handhabung, Verschmutzung, Veränderungen am Gerät, einen Unfall oder auf anormale Betriebsbedingungen, einschließlich durch außerhalb der für das Produkt spezifizierten Belastbarkeit verursachten Überspannungsfehlern, zurückzuführen ist, wird Fluke dem Erwerber einen Voranschlag der Reparaturkosten zukommen lassen und erst die Zustimmung des Erwerbers einholen, bevor die Arbeiten begonnen werden. Nach der Reparatur wird das Produkt unter Vorauszahlung der Frachtkosten an den Erwerber zurückgeschickt, und es werden dem Erwerber die Reparaturkosten und die Versandkosten (FOB Versandort) in Rechnung gestellt.

DIE VORSTEHENDEN GARANTIEBESTIMMUNGEN STELLEN DEN EINZIGEN UND ALLEINIGEN RECHTSANSPRUCH AUF SCHADENERSATZ DES ERWERBERS DAR UND GELTEN AUSSCHLIESSLICH UND AN STELLE VON ALLEN ANDEREN VERTRAGLICHEN ODER GESETZLICHEN GEWÄHRLEISTUNGSPFLICHTEN, EINSCHLIESSLICH - JEDOCH NICHT DARAUF BESCHRÄNKT - DER GESETZLICHEN GEWÄHRLEISTUNG DER MARKTFÄHIGKEIT, DER GEBRAUCHSEIGNUNG UND DER ZWECKDIENLICHKEIT FÜR EINEN BESTIMMTEN EINSATZ.FLUKE HAFTET NICHT FÜR SPEZIELLE, UNMITTELBARE, MITTELBARE, BEGLEIT- ODER FOLGESCHÄDEN ODER VERLUSTE, EINSCHLIESSLICH VERLUST VON DATEN, UNABHÄNGIG VON DER URSACHE ODER THEORIE.

Angesichts der Tatsache, daß in einigen Ländern die Begrenzung einer gesetzlichen Gewährleistung sowie der Ausschluß oder die Begrenzung von Begleit- oder Folgeschäden nicht zulässig ist, kann es sein, daß die obengenannten Einschränkungen und Ausschlüsse nicht für jeden Erwerber gelten.Sollte eine Klausel dieser Garantiebestimmungen von einem zuständigen Gericht oder einer anderen Entscheidungsinstanz für unwirksam oder nicht durchsetzbar befunden werden, so bleiben die Wirksamkeit oder Durchsetzbarkeit irgendeiner anderen Klausel dieser Garantiebestimmungen von einem solchen Spruch unberührt.

LIMITES DE GARANTIE ET DE RESPONSABILITE

La société Fluke garantit l’absence de vices de matériaux et de fabrication de ses produits dans des conditions normales d’utilisation et d’entretien. La période de garantie est de deux ans et prend effet à la date d’expédition. Les pièces, les réparations de produit et les services sont garantis pour une période de 90 jours. Cette garantie ne s’applique qu’à l’acheteur d’origine ou à l’utilisateur final s’il est client d’un distributeur agréé par Fluke, et ne couvre pas les fusibles, les batteries/piles interchangeables ni aucun produit qui, de l’avis de Fluke, a été malmené, modifié, négligé, contaminé ou endommagé par accident ou soumis à des conditions anormales d’utilisation et de manipulation. Fluke garantit que le logiciel fonctionnera en grande partie conformément à ses spécifications fonctionnelles pour une période de 90 jours et qu’il a été correctement enregistré sur des supports non défectueux. Fluke ne garantit pas que le logiciel est exempt d’erreurs ou qu’il fonctionnera sans interruption.

Les distributeurs agréés par Fluke appliqueront cette garantie à des produits vendus neufs et qui n’ont pas servi, mais ils ne sont pas autorisés à offrir une garantie plus étendue ou différente au nom de Fluke. Le support de garantie est offert uniquement si le produit a été acheté à un point de vente agréé par Fluke ou bien si l’acheteur a payé le prix international applicable. Fluke se réserve le droit de facturer à l’acheteur les frais d’importation des pièces de réparation ou de remplacement si le produit acheté dans un pays a été expédié dans un autre pays pour y être réparé.

L’obligation de garantie de Fluke est limitée, au choix de Fluke, au remboursement du prix d’achat, ou à la réparation/remplacement gratuit d’un produit défectueux retourné dans le délai de garantie à un centre de service agréé par Fluke.

Pour avoir recours au service de la garantie, mettez-vous en rapport avec le centre de service agréé Fluke le plus proche pour recevoir les références d’autorisation de renvoi, puis envoyez le produit, accompagné d’une description du problème, port et assurance payés (franco lieu de destination), à ce centre de service. Fluke décline toute responsabilité en cas de dégradations survenues au cours du transport. Après une réparation sous garantie, le produit sera retourné à l’acheteur, en port payé (franco lieu de destination). Si Fluke estime que le problème a été causé par une négligence, un mauvais traitement, une contamination, une modification, un accident ou des conditions de fonctionnement ou de manipulation anormales, notamment de surtensions liées à une utilisation du produit en dehors des spécifications nominales, ou de l’usure normale des composants mécaniques, Fluke fournira un devis des frais de réparation et ne commencera la réparation qu’après en avoir reçu l’autorisation. Après la réparation, le produit sera renvoyé à l’acheteur, en port payé (franco point d’expédition) et les frais de réparation et de transport lui seront facturés.

LA PRÉSENTE GARANTIE EST EXCLUSIVE ET TIENT LIEU DE TOUTES AUTRES GARANTIES, EXPRESSES OU IMPLICITES, Y COMPRIS, MAIS NON EXCLUSIVEMENT, TOUTE GARANTIE IMPLICITE DE VALEUR MARCHANDE OU D’ADÉQUATION À UN USAGE PARTICULIER. FLUKE NE POURRA ETRE TENU RESPONSABLE D’AUCUN DOMMAGE PARTICULIER, INDIRECT, ACCIDENTEL OU CONSECUTIF, NI D’AUCUN DEGAT OU PERTE, DE DONNEES NOTAMMENT, SUR UNE BASE CONTRACTUELLE, EXTRA-CONTRACTUELLE OU AUTRE.

Etant donné que certains pays ou états n’admettent pas les limitations d’une condition de garantie implicite, ou l’exclusion ou la limitation de dégâts accidentels ou consécutifs, il se peut que les limitations et les exclusions de cette garantie ne s’appliquent pas à chaque acheteur. Si une disposition quelconque de cette garantie est jugée non valide ou inapplicable par un tribunal ou un autre pouvoir décisionnel compétent, une telle décision n’affectera en rien la validité ou le caractère exécutoire de toute autre disposition.

有限保证和责任限制

在正常使用和维护条件下，Fluke 公司保证每一个产品都没有材料缺陷和制造工艺问题。保证期为从产品发货之日起二年。部件、产品修理和服务的保证期限为 90 天。本项保证仅向授权零售商的原始买方或最终用户提供，并且不适用于保险丝和一次性电池或者任何被 Fluke 公司认定由于误用、改变、疏忽、意外、非正常操作和使用所造成的产品损坏。Fluke 公司保证软件能够在完全符合性能指标的条件下至少操作 90 天，而且软件是正确地记录在无缺陷的媒体上。Fluke 公司并不保证软件没有错误或无操作中断。

Fluke 公司仅授权零售商为最终客户提供新产品或未使用过产品的保证。但并未授权他们代表 Fluke 公司提供范围更广或内容不同的保证。只有通过 Fluke 授权的销售商购买的产品，或者买方已经按适当的国际价格付款的产品，才能享受 Fluke 的保证支持。在一个国家购买的产品被送往另一个国家维修时，Fluke 公司保留向买方收取修理/更换零部件的进口费用的权利。

Fluke 公司的保证责任是有限的，Fluke 公司可以选择是否将依购买价退款、免费维修或更换在保证期内退回到 Fluke 公司委托服务中心的有缺陷产品。

要求保修服务时，请与就近的 Fluke 授权服务中心联系，获得退还授权信息；然后将产品连同问题描述寄至该服务中心，并预付邮资和保险费用（目的地离岸价格）。Fluke 对运送途中发生的损坏不承担责任。在保修之后，产品将被寄回给买方并提前支付运输费（目的地交货）。如果 Fluke 认定产品故障是由于疏忽、滥用、污染、修改、意外或不当操作或处理状况而产生，包含使用超出产品特的特定额定值而导致过电压故障，或是由于机件日常使用耗损，则 Fluke 会估计修理费用，在实际修理之前先获得买方同意。在修理之后，产品将被寄回给买方并预付运输费；买方将收到修理和返程运输费用（寄发地交货）的帐单。

本保证为买方唯一能获得的全部赔偿内容，并且取代所有其它明示或隐含的保证，包括但不限于适销性或适用于特殊目的的任何隐含保证。FLUKE 不应对由于任何原因或推理所发生的任何特殊、间接、偶发或后续的损坏或损失承担赔偿责任，包括数据丢失。

由于某些国家或州不允许对隐含保证的期限加以限制、或者排除和限制意外或后续损坏，本保证的限制和排除责任条款可能并不对每一个买方都适用。如果本保证的某些条款被法院或其它具有适当管辖权的裁决机构判定为无效或不可执行，则此类判决将不影响任何其它条款的有效性或可执行性。

Functions

The Power Analyzer allows for the analysis of currents from dc to several MHz. Voltage values up to 1000 V and currents up to 20 A (depending on measurement modules installed in the instrument) are measured accurately, and the respective real, reactive, and apparent power is calculated. The limit of error is between 0.03 % and 0.3 %, depending on the model. See the technical specifications for detailed information. For dc and ac up to a few MHz, it is not affected by the wave shape, frequency, or phase position. The measuring range can be extended by connecting shunts or clamps. When extending the range using third-party shunts or clamp, the extra errors due to these devices should be considered. The device allows for simultaneous measuring in up to six channels.

Before You Begin 5

Before You Begin

Carefully read and adhere to the following warning statements before you connect the Power Analyzer.

XW Warning

To avoid possible electric shock or personal injury:

• By connecting the Power Analyzer to active circuits, the

terminals and certain parts inside the Power Analyzer are live.

• To ensure safe operation, first connect the Power

Analyzer to the power supply.

• If possible, open the circuit before establishing a

connection to the Power Analyzer.

• Before connecting the circuits, ensure that the maximum

measuring voltage and maximum voltage to earth ground (1000 V CATII and 600 V CATIII respectively) are not exceeded.

• Do not use leads and accessories that do not comply

with relevant safety standards, as this could lead to serious injury or death from electric shock.

• To avoid damage to the instrument, never apply voltage

to the current shunt inputs (lower set of input jacks, blue).

NORMA 4000/5000

Operators Manual

Overview

1-Phase Measurement

Direct Connection

The Fluke NORMA 4000/5000 Power Analyzer offers the following options for connection:

• 1-phase measurement

• Aron circuit (W2)

• 3-phase measurement (W3)

Note

When connecting a 4-channel device for electrical efficiency analysis, the 3-phase power cables for this measurement should be connected to the measuring channels 1 to 3, so that the efficiency can be calculated and displayed directly on the Power Analyzer.

• Ensure that there is no overload at the current input of the Power Analyzer.

• If necessary, install appropriate fuses.

XW Warning

To avoid possible electric shock or personal injury:

• Risk of injury when touching connections, internal circuits

and measuring devices that are not connected to earth ground.

• Always adhere to the instructions regarding the sequence

of connection (see Chapter 5, “Connecting Sequence”).

The difference between the connection of the voltage input between the current input and the mains (Figure 5-1) or between the current input and the load (Figure 5-2) is that, in the first case, the leakage power of the current input, and in the second, the leakage power of the voltage input is added to the measuring result. As the leakage power of the current input may increase up to ~2 W at 10 amp versus a leakage power of the voltage input of 0.5 W at 1000 V, it is preferable to use the second method. It is used for the further diagrams, also in Aron and 3-phase measurements. For special applications such as active current sensors without power loss or higher leakage power at the voltage input with the “star point adapter,” method 1 is preferable.

Operators Manual

Measurement with Shunt

The connecting leads to the shunts should be as short as possible in order to prevent interference and noise voltages.

XW Warning

To avoid possible electric shock or personal injury:

• Do not touch sensing terminals. The sense terminals at the

shunts are powered with the same voltage as the power connections.

• Shunts are not isolated. Never touch the sense terminals at

the shunts.

• Risk of injury when touching connections, internal circuits,

and measuring devices that are not earthed.

• Always adhere to the instructions regarding the connection

sequence (see Chapter 5, “Connecting Sequence”).

Where the current to be measured exceeds the rating of the direct current connection, an external triaxial shunt should be used, see Figure 5-3. Fluke triaxial shunts are recommended as they provide high accuracy across the full frequency range. Standard linear shunts may produce excessive errors due to the possible presence of high frequency that components experience with electronic loads. The NORMA internal shunt is optimized for such loads.

Note

In Figures 5-3, 5-6, and 5-9, Fluke recommends using MCS measuring leads for triaxial shunts and MCP leads for planar shunts. Triaxial shunts are equipped with guard connectors in the plugs and planar shunts are equipped with guard sockets.

Measurement with Voltage and Current Transducer

Figure 5-4 shows the connections for measurements with a voltage and current transducer.

W Caution

To prevent damage to the transducer due to overload, check transducer rating.

Note

Transducer errors limit the measuring bandwidth and reduce the intrinsic uncertainty.

XW Warning

To avoid possible electric shock or personal injury:

• Risk of injury when touching connections, internal circuits,

and measuring devices that are not connected to earth ground.

Operators Manual

Aron Circuit (2-Wattmeter Method, W2)

Direct Connection

The Aron circuit is only available for 3-wire networks, see Figure 5-5. It is only required to measure two phases (currents I1 and I2 in the following connection diagrams), as I1+I2+I3 must be 0.

Note

In most cases, the Aron circuit is not acceptable for measurements on inverters, as there are capacitive leakage currents from the windings to the housing.

• Ensure that there is no overload at the current input of the Power

Analyzer.

• If necessary, install appropriate fuses.

To select the Aron, or 2-wattmeter, Method, go to General Setup and select W2. Select channels 2 and 3 for the connections. For more information, see Chapter 7, “Configuration.”

Scaling transformers for voltage and current may be used in this mode but care needs to made in identifying the correct channel and measurement index information.

Note

The W2 mode is not provided for the second set of three phase inputs with the 4 or 6 channel versions of the NORMA 5000.

XW Warning

To avoid possible electric shock or personal injury:

• Risk of injury when touching connections, internal circuits,

and measuring devices that are not connected to earth ground.

• Always adhere to the instructions regarding the sequence of

In systems with three voltage wires, the three wires should be connected to the HI terminal and the LO terminals should be connected together.

However, in high frequency switching electronics systems such as drives, inverters, and UPS, this method has additional errors due to high frequency components being shunted to the ground connection. To compensate for this error, use the star point adapter, see Figure 5-11.

Set Up for Measuring 7

Set Up for Measuring

Prior to measuring, you must configure the default settings, adjust channels, measuring ranges and times, and synchronize current and voltage sources.

If you wish to reapply certain settings at a later stage, you must save the configuration. You have the option to save up to 15 user-defined configurations, which are automatically assigned the names 10:USER to 24:USER.

Configuration

When first switching on the Power Analyzer, factory configuration 1 and 2:W2 is used. This configuration is suitable for measurements with fundamentals below 100 Hz (average time 300 ms, synchronization source U1, low-pass filter 100 Hz).

Mode W3 is the standard configuration for three phase, 3-wattmeter measurement and single phase measurement. Channels 1, 2, and 3 are used for three-phase measurements in a 3-channel instrument, considering three-channel average values and totals. In 4-channel instruments, channel 4 acts as an independent single channel. In 6-channel configurations, the W3 connection operates as two independent three-phase systems.

In 4- or 6-channel instruments where the W2 configuration is selected, the channels higher than 3 operate as the W3 configuration.

Note

You have the option to modify the settings for configuration 1:W3. If you wish to save the new settings, you must do this in a new configuration. Default configuration 1 and 2:W2 cannot be overwritten. You may save new settings in the process or at the end of the configuration procedure. Settings that have not been saved are lost when the device is switched off or when a different configuration is loaded.

You may:

• Modify configuration 1:W3 loaded upon startup of the device

• Load an existing configuration

• Create a new configuration

• Delete or modify an existing configuration

U6, I1 through I6).

• Ext for external synchronization signal (connection to port for external

synchronization signal).

• OFF, if no synchronization source is used (such as measuring of direct current).

To measure the start up of a machine, you might opt for an external synchronization signal (0.2 Hz to sample rate, max. 50 V), as there is otherwise no signal at the beginning of the measuring procedure, and thus no measured values.

For signal analysis like DSO (scope) or harmonic analysis (FFT) with digital sampling procedures, you need to consider Shannon’s sampling theorem that states: “The sample frequency must be, at minimum, double that of the highest signal frequency.” If not considered, it may result in display values (frequencies or waveforms) that do not exist, in other words, aliasing.

If you want to measure numeric time-based mean values like rms, rectified mean, and mean, you do need not observe Shannon’s theorem. For the precision of the results, only the number of samples is important, not the sampling frequency (average time >> cycle duration). The sampling signal must be statistically independent, which means the sampling frequency must not be close to, or a multiple of, the signal frequency.

Note

To operate in the “undersampling mode,” the anti-aliasing filter must be turned OFF at the current and voltage channel (see the earlier section “Configure Current and Voltage Channels” in this chapter).

Introduction 8

Introduction

The Fluke NORMA 4000/5000 Power Analyzer is designed for the measuring of currents and voltages for up to three different channels. The Power Analyzer calculates rms values, real, apparent and reactive power, and other derived values. The accuracy is not affected by the wave form, frequency, or phase shift. Harmonics may be displayed to a maximum of half the sampling frequency.

Default settings are available for loading quick setups. In addition, you can define more specific settings to save and load as required (see, "Configuration" in Chapter 7). The Power Analyzer begins a measurement as soon as the configuration is set and the device is switched on.

Prior to Measuring

Connect Power Analyzer to the mains (power) socket.

1. Check the measuring connections at the Power Analyzer.

2. Switch on the Power Analyzer.

Measuring with Default Configuration

If the default configuration is acceptable, no additional steps are required.

Ensure that the factory configuration is loaded (see, "Load Configuration" in Chapter 7).

Measuring with User-Defined Configuration

If custom analysis is required, load the respective configuration (see "Configuration" in Chapter 7).

Note

If measurements with an external shunt or probe are required, make sure that there is no signal connected at the direct current inputs. Signals on both inputs (external- and direct-current input) can damage the measurement unit.
