Lifetime Limited Warranty

Each Fluke 20, 70, 80, 170, 180 and 280 Series DMM will be free from defects in material and workmanship for its lifetime. As

used herein, “lifetime” is defined as seven years after Fluke discontinues manufacturing the product, but the warranty period

shall be at least ten years from the date of purchase. This warranty does not cover fuses, disposable batteries, damage from

neglect, misuse, contamination, alteration, accident or abnormal conditions of operation or handling, including failures caused

by use outside of the product’s specifications, or normal wear and tear of mechanical components. This warranty covers the

original purchaser only and is not transferable.

For ten years from the date of purchase, this warranty also covers the LCD. Thereafter, for the lifetime of the DMM, Fluke will

replace the LCD for a fee based on then current component acquisition costs.

To establish original ownership and prove date of purchase, please complete and return the registration card accompanying

the product, or register your product on http://www.fluke.com. Fluke will, at its option, repair at no charge, replace or refund

the purchase price of a defective product purchased through a Fluke authorized sales outlet and at the applicable international

price. Fluke reserves the right to charge for importation costs of repair/replacement parts if the product purchased in one

country is sent for repair elsewhere.

If the product is defective, 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. Fluke will pay return transportation for product repaired or replaced in-warranty.

Before making any non-warranty repair, Fluke will estimate cost and obtain authorization, then invoice you for repair and re-

turn transportation.

THIS WARRANTY IS YOUR ONLY REMEDY. NO OTHER WARRANTIES, SUCH AS FITNESS FOR A PARTICULAR PURPOSE,

ARE EXPRESSED OR IMPLIED. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSE-

QUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR THEORY. AUTHORIZED RE-

SELLERS ARE NOT AUTHORIZED TO EXTEND ANY DIFFERENT WARRANTY ON FLUKE’S BEHALF. Since some states do not

allow the exclusion or limitation of an implied warranty or of incidental or consequential damages, this limitation of liability

may not apply to you. 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.

Introduction

XWWarning

Read “Safety Information” before using this Meter

Except where noted, the descriptions and instructions in this manual

apply to both the Fluke 287 and 289 True-rms Digital Multimeters

(hereafter referred to as “the Meter”). Model 289 appears in all

illustrations.

This manual covers information for turning on the Meter, understanding

its controls, and basic maintenance. For complete operational

instructions, refer to the 287/289 Users Manual contained on the

accompanying CD.

Safety Information

The Meter complies with:

•ANSI/ISA 82.02.01 (61010-1) 2004

•UL 61010B (2003)

•CAN/CSA-C22.2 No. 61010-1-04

•IEC/EN 61010-1 2nd Edition Pollution Degree 2

•EMC EN 61326-1

•Measurement Category III, 1000V, Pollution Degree 2

•Measurement Category IV, 600 V, Pollution Degree 2

In this manual, a Warning identifies hazardous conditions and actions

that could cause bodily harm or death. A Caution identifies conditions

and actions that could damage the Meter, the equipment under test, or

cause permanent loss of data.

Symbols used on the Meter and in this manual are explained in Table 1.

XWWarning

To avoid possible electric shock or personal injury, follow

these guidelines:

•Use this Meter only as specified in this manual or the

protection provided by the Meter might be impaired.

•Do not use the Meter if it is damaged. Before you use

the Meter, inspect the case. Look for cracks or

missing plastic. Pay particular attention to the

insulation surrounding the connectors.

•Make sure the battery door is closed and latched

before operating the Meter.

287/289

Getting Started

•Remove test leads from the Meter before opening the

battery door.

•Inspect the test leads for damaged insulation or

exposed metal. Check the test leads for continuity.

Replace damaged test leads before you use the Meter.

•Do not apply more than the rated voltage, as marked

on the Meter, between the terminals or between any

terminal and earth ground.

•Never operate the Meter with the cover removed or the

case open.

•Use caution when working with voltages above 30 V ac

rms, 42 V ac peak, or 60 V dc. These voltages pose a

shock hazard.

•Use only the replacement fuses specified by the

manual.

•Use the proper terminals, function, and range for

measurements.

•Avoid working alone.

•When measuring current, turn off circuit power before

connecting the Meter in the circuit. Remember to

place the Meter in series with the circuit.

•When making electrical connections, connect the

common test lead before connecting the live test lead;

when disconnecting, disconnect the live test lead

before disconnecting the common test lead.

•Do not use the Meter if it operates abnormally.

Protection may be impaired. When in doubt, have the

Meter serviced.

•Do not operate the Meter around explosive gas, vapor,

or dust.

•Use only 1.5 V AA batteries, properly installed in the

Meter case, to power the Meter.

•When servicing the Meter, use only specified

replacement parts.

•When using probes, keep fingers behind the finger

guards on the probes.

•Do not use the Low Pass Filter option to verify the

presence of hazardous voltages. Voltages greater than

what is indicated may be present. First, make a

voltage measurement without the filter to detect the

possible presence of hazardous voltage. Then select

the filter function.

•Only use test leads that have the same voltage,

category, and amperage ratings as the meter and that

have been approved by a safety agency.

•Use proper protective equipment, as required by local

or national authorities when working in hazardous

areas.

•Comply with local and national safety requirements

when working in hazardous locations.

WCaution

To avoid possible damage to the Meter or the equipment

under test, follow these guidelines:

•Disconnect circuit power and discharge all high

voltage capacitors before testing resistance,

continuity, diodes, or capacitance.

•Use the proper terminals, function, and range for all

measurements.

•Do not remove batteries while the Meter is turned on

or a signal is applied to the Meter’s input jacks.

•Before measuring current, check the Meter's fuses.

(See "Testing the Fuses" in the Users Manual on the

accompanying CD.)

•Do not use the LoZ mode to measure voltages in

circuits that could be damaged by this mode’s low

impedance (≈3 kΩ). (model 289 only)

Turning the Meter On

With the Meter off, press Oto turn on the Meter. Pressing Owhile the

Meter is on, causes it to turn off.

Setting the Meter’s Language

The Meter comes from the factory with the display language set to

English. To select another language, open the setup menu by pressing

the softkey labeled Setup. Move the menu selector next to the menu item

labeled Display. Next, press the softkey labeled Format (F2) to open the

format menu. If not already selected, move the menu selector to the left

of the menu item labeled Language and press the softkey labeled Edit.

The currently selected language becomes highlighted and fappears to

the right of the language. Use 7and 8to scroll through the available

languages, then press the softkey labeled OK to set the Meter’s display

language. Press the softkey labeled Close to return to normal Meter

operation.
