Introduction

XWWarning

To avoid electric shock or personal injury,

read "Safety Information” and all Warnings

before using the Meter.

The Fluke Model 15B and Model 17B Multimeters

(hereafter referred to as “the Meter”) are 4,000 count

instruments.

This equipment is intended for use in business

environments and is not to be used in homes. The Meter

is battery powered with a digital display.

Except where noted, the descriptions and instructions in

this Users Manual apply to both the Model 15B and

Model 17B Multimeters.

Unless otherwise identified, all illustrations show the

Model 17B.

Safety Information

The Fluke Model 15B and 17B comply with IEC 61010-

1:2001 Second Edition CAT II 1000 V, CAT III 600 V

overvoltage standards. See Specifications.

Use the Meter only as specified in this manual, otherwise

the protection provided by the Meter may be impaired.

In this manual, a Warning identifies conditions and

actions that pose hazards to the user.

A Caution identifies conditions and actions that may

damage the Meter or the equipment under test.

International symbols used on the Meter and in this

manual are explained in Table 1.

Safe Working Practices

Review the safety information and comply with the safe

working practices on pages 2 and 3.

15B & 17B

Users Manual

XWWarning

To prevent possible electrical shock, fire, or

personal injury:

•Read all safety Information before you

use the Product.

•Carefully read all instructions.

•Examine the case before you use the

Product. Look for cracks or missing

plastic. Carefully look at the insulation

around the terminals.

•Do not use and disable the Product if it

is damaged.

•Do not use the Product if it operates

incorrectly.

•Do not touch voltages > 30 V ac rms, 42

V ac peak, or 60 V dc.

•Limit operation to the specified

measurement category, voltage, or

amperage ratings.

•Use the Product only as specified, or the

protection supplied by the Product can

be compromised.

•Replace the batteries when the low

battery indicator shows to prevent

incorrect measurements.

•Comply with local and national safety

codes. Use personal protective

equipment (approved rubber gloves, face

protection, and flame-resistant clothes)

to prevent shock and arc blast injury

where hazardous live conductors are

exposed.

•Do not apply more than the rated voltage,

between the terminals or between each

terminal and earth ground.

•Measure a known voltage first to make

sure that the Product operates correctly.

•Use the correct terminals, function, and

range for measurements.

•Do not use the Product around explosive

gas, vapor, or in damp or wet

environments.

•Do not use test leads if they are

damaged. Examine the test leads for

damaged insulation, exposed metal, or if

the wear indicator shows. Check test

lead continuity.

Multimeters

Safe Working Practices

•Use only current probes, test leads, and

adapters supplied with the Product.

•Connect the common test lead before

the live test lead and remove the live test

lead before the common test lead.

•Keep fingers behind the finger guards on

the probes.

•Only use probes, test leads, and

accessories that have the same

measurement category, voltage, and

amperage ratings as the Product.

•Remove all probes, test leads, and

accessories before the battery door is

opened.

•Do not exceed the Measurement

Category (CAT) rating of the lowest rated

individual component of a Product,

probe, or accessory.

MEASUREMENT CATEGORY II is applicable to test and

measuring circuits connected directly to utilization points

(socket outlets and similar points) of the low-voltage

MAINS installation. This part of the installation is expected

to have a minimum of three levels of overcurrent protective

devices between the transformer and the connecting points

of the measuring circuit.

CAT III

MEASUREMENT CATEGORY III is applicable to

test and measuring circuits connected to the

distribution part of the building’s low-voltage MAINS

installation. This part of the installation is expected

to have a minimum of two levels of over-current

protective devices between the transformer and

possible connecting points.

This product complies with the WEEE Directive

(2002/96/EC) marking requirements. The affixed label

indicates that you must not discard this electrical/electronic

product in domestic household waste. Product Category:

With reference to the equipment types in the WEEE

Directive Annex I, this product is classed as category 9

"Monitoring and Control Instrumentation" product. Do not

dispose of this product as unsorted municipal waste. Go to

Fluke’s website for recycling information.

Users Manual

Battery Saver

The Meter enters the “Sleep mode” and blanks the display

if the Meter is not used and the input is inactive for 30

minutes. Press any button or turn the rotary switch to

wake the Meter up. To disable the Sleep mode, hold down

the YELLOW button while turning the Meter on.

Making Measurements

Manual Ranging and Auto Ranging

The Meter has both manual and auto range options. In the

auto range mode, the Meter selects the best range for the

input detected. This allows you to switch test points

without having to reset the range. You can override auto

ranging by selecting the range manually.

The Meter defaults to the auto range mode in

measurement functions that have more than one range.

When the Meter is in the auto range mode, Auto Range is

displayed.

To enter and exit the manual range mode:

1. Press

.

Each press of increments the range. When the

highest range is reached, the Meter wraps to the

lowest range.

2. To exit the manual range mode, press and hold 

for two seconds.

Data Hold

XWWarning

Dangerous voltages may be present at the

input terminals and may not be displayed.

To hold the present reading, press . Press again

to resume normal operation.

Relative Measurements (17B only)

The Meter will display relative measurements in all

functions except frequency.

1. With the Meter in the desired function, touch the test

leads to the circuit on which you want future

measurements to be based.

2. Press

to store the measured value as the

reference value and activate the relative

measurement mode. The difference between the

reference value and subsequent reading is displayed.

3. Press

for more than 2 seconds to return the

Meter to normal operation.

Measuring AC and DC Voltage

To minimize improper reading of an unknown voltage

containing either ac or ac + dc voltage components, first

select the ac voltage function on the meter making

particular note of the ac range required for a good

measurement. Next manually select the dc function with

the dc range that either matches or is higher than the

previously noted ac range. Using this procedure minimizes
