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 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, 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 cou nt ry.

Fluke’s warranty obligation is limit ed, at Fluk e’s option , to refu nd of the pu rch ase pri ce, fr ee of cha rge repai r, or re pl ac em ent of a defective pro duct whic h 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, contami-

nation, 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. 11/99

Read 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, switc h posi ti on, a nd ra nge for meas urements.

• Verify the Meter’s operation by measuring a known voltage. If i n doubt, have the Met er serv ic e d.

• 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 batte ry indicator (

• 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 battery­powered, 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 I to IV) based on the magnitude of danger from t rans i ent
impulses. CAT III meters are designed to protect against
transients in fixed-equi pm ent installations at t he di s tribution level.

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.

Warning

To avoid personal injury or damage to the Meter:

• Never attempt to make an in-circuit current measure-

ment when the open-circuit potential to earth is

> 600 V.

• Check the Meter's fuse before testing. (See “Testing

the Fuse”)

• Use the proper terminals, switch position, and range

for your measurement.

• Never place the probes in parallel with a circuit or

component when the leads are plugged into the
current terminals.

Turn power OFF, break circuit, insert Meter in series, turn

Measuring Frequency

W

Warning

To avoid electrical shock, disregard the bar graph for
frequencies > 500 Hz. If the frequency of the measured
signal is > 500 Hz, the bar graph is unspecified.

The Meter measures the frequency of a signal by counting the
number of times the signal crosses a trigger level each s econd.
The trigger level is 0 V, 0 A f or al l ranges.

⇒ Select progressively lower ranges using manual ranging for a

stable reading.

Using the Bar Graph

The bar graph is like the needle on an analog meter. It has an
overload indicator (>) to the right and a polarity indicator (±) to
the left.

Because the bar graph updates about 40 ti mes per second, which
is ten times faster than the digital display, the bar graph is useful
for making peak and null adjust m ents.

The bar graph is disabled when measuring capac i tance. In
frequency, the bar graph and range annunciator i ndi cate the
underlying voltage or current.

The number of segments indicates the measured value and is
relative to the full-s cale value of the selected range, except on the
10 A ranges

.

In the 60 V range, for example (s ee bel ow), the major divisions on
the scale represent 0, 30, and 60 V . An input of −30 V turns on
the negative sign and the segments up to the middle of the scale.

Cleaning

Wipe the case with a damp clot h and mild detergent. Do not use
abrasives or solvents . Dirt or moisture in the termi nal s can affect

To remove the battery door:

1. Remove screw from battery door.

2. Use the finger recess to l i ft door slightly.
