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.

"Warning" and "Caution" Statements
A "WWarning" statement identif i es hazardous conditions and
actions that could c ause bodily harm or death.
A "Caution" statement i dentifies conditions and ac tions that could
damage the Meter or the equipment under tes t.
Unsafe Voltage
To alert you to the presence of a potentially hazardous volt age,
the
