Introduction

XWWarning

To avoid electric shock or personal injury,

read "Safety Information” and “Warning and

Precautions” before using the Meter.

The Fluke Model 15B and Model 17B Multimeters

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

instruments.

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 1010-1

CAT I 1000 V, CAT II 600 V, and CAT III 300 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

XWWarnings and Precautions

To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the

equipment under test, comply with the following practices:

⇒Before using the Meter, inspect the case. Do not use the Meter if it is damaged. Look for cracks or missing plastic. Pay

particular attention to the insulation around the connectors.

⇒Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. Replace damaged

test leads before using the Meter.

⇒Verify a Meter’s operation by measuring a known voltage. Do not use the Meter if it operates abnormally. Protection

may be impaired. When in doubt, have the Meter serviced.

⇒Do not apply more than the rated voltage, as marked on the Meter, between the terminals or between any terminal and

earth ground.

⇒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 the proper terminals, function, and range for your measurements.

⇒Do not operate the Meter around explosive gas, vapor, or dust.

⇒When using the probes, keep the fingers behind the finger guards.

⇒When making 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.

⇒Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or

capacitance.

⇒Do not use the Meter in a manner not specified by this manual or the safety features of the Meter may be impaired.

⇒For all dc functions, including manual or auto-ranging, to avoid the risk of shock due to possible improper reading,

verify the presence of any ac voltages by first using the ac function. Then select a dc voltage range equal to or greater

than the ac range.

Safe Working Practices

XW Warnings and Precautions (Continued)

⇒Before measuring current, check the Meter’s fuses (see “Testing the Fuses”) and turn OFF power to the circuit before

connecting the Meter to the circuit.

⇒Do not operate the Meter with the case (or part of the case) removed.

⇒Use only two AA batteries, properly installed in the Meter case, to power the Meter.

⇒Replace the battery as soon as the battery indicator (M) appears. With a low battery, the Meter might produce false

readings that can lead to electric shock and personal injury.

⇒Do not measure voltages above 600 V in Category II, or 300 V in Category III installations.

⇒When in REL mode the Δsymbol is displayed. Caution must be used because hazardous voltage may be present.

⇒Remove test leads from the Meter before opening the Meter case or battery door.

⇒When servicing the Meter, use only specified replacement parts.

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 Rincrements 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 R

for two seconds.

XW Warning

Dangerous voltages may be present at the

input terminals and may not be displayed.

Data Hold

To hold the present reading, press H. Press Hagain

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

rto 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

rfor 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
