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 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, al-

tered, 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 differ-

ent 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 applica-

ble international price. Fluke reserves the right to invoice Buyer for importation costs of repair/replacement parts when product purchased in one country is sub-

mitted for repair in another country.

WRead Before Using the Meter: Warnings and Precautions

To avoid possible electric shock or personal injury, follow these guidelines:

•Use the Meter only as specified in this manual or the protection provided by the Meter might be impaired.

•Do not use the Meter or test leads if they appear damaged, or if the Meter is not operating properly.

•Always use proper terminals, switch position, and range for measurements.

•Verify the Meter's operation by measuring a known voltage. If in doubt, have the Meter serviced.

•Do not apply more than the rated voltage, as marked on Meter, between terminals or between any terminal and earth ground.

•Use caution with voltages above 30 V ac rms, 42 V ac peak, or 60 V dc. These voltages pose a shock hazard.

•To avoid false readings that can lead to electric shock and injury, replace the battery as soon as the low battery indicator (N) appears.

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

•Do not use the Meter around explosive gas or vapor.

•When using test leads or probes, keep your fingers behind the finger guards.

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

True RMS Multimeters

The Fluke Model 110, Model 111, and Model 112 are battery-

powered, true-RMS multimeters (hereafter "the Meter") with a

6000-count display and a bar graph. This manual applies to all

three models. All figures show the Model 112.

The Meter measures or tests the following:

•AC / DC voltage and current

•Resistance

•Continuity

•Diodes

•Voltage and current frequency

•Capacitance

These meters meet CAT III IEC 61010-1-95 standards. The IEC

61010-1-95 safety standard defines four overvoltage categories

(CAT Ito IV) based on the magnitude of danger from transient

impulses. CAT III meters are designed to protect against

transients in fixed-equipment installations at the distribution level.

Making Basic Measurements

The figures on the following pages show how to make basic

measurements.

When connecting the test leads to the circuit or device, connect

the common (COM) test lead before connecting the live lead;

when removing the test leads, remove the live lead before

removing the common test lead.

WWarning

To avoid electric shock, injury, or damage to the Meter,

disconnect circuit power and discharge all high-voltage

capacitors before testing resistance, continuity, diodes,

or capacitance.

Note

In reading AC voltage or current, for the integrated RMS

converter to correctly measure distorted waveforms, reading

settling time increases to several seconds at the low end of

AC voltage and current ranges.

Because inputs below 5% of range are not specified, it is

normal for this meter to display non-zero readings when the

test leads are disconnected from a circuit or are shorted

together.

Volts DCVolts AC

aej03f.eps

Understanding AC Zero Input Behavior of True RMS Meters

Unlike averaging meters, which can accurately measure only pure

sinewaves, True RMS meters accurately measure distorted

waveforms. Calculating True RMS converters require a certain

level of input voltage to make a measurement. This is why AC

voltage and current ranges are specified from 5% of range to

100% of range. Non-zero digits that are displayed on a True RMS

meter when the test leads are open or are shorted are normal.

They do not affect the specified AC accuracy above 5% of range.

The input levels that are unspecified are:

•AC voltage: below 5% of 6000 mV AC, or 300 mV AC

•AC current: below 5% of 60 A AC, or 3.00 A AC
