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 one year 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 cus-
tomers only but have no authority to extend a greater or different warranty on behalf of Fluke. War-
ranty 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 country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge
repair, or replacement of a defective product which 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 au-
thorization 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. Fol-
lowing warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination).
If Fluke determines that failure was caused by neglect, misuse, contamination, 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 WAR-
RANTY 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 en-
forceability of any other provision.

Safety Instructions
Please read this section carefully. It will familiarize you with important safety
instructions for handling your Clamp Meter. In this manual a
Warning
identifies conditions and actions that pose hazard(s) to the user. A Caution
identifies conditions and actions that may damage the test instrument.
The design and manufacture of the device conforms to the latest state of
technology and the safety standards specified in IEC 61010-1/ 2
nd
edition. If
used improperly, there is a risk of damage to persons and property.
W X Warning
Review the entire manual before using the Clamp Meter
and its accessories. To avoid electrical shock or fire:
Use the Meter only as specified in this manual or the
protection provided by the Meter might be impaired.
Use caution when working with voltages above 33 V
acrms, 46.7 V ac peak, or 70 V dc. These voltages pose
ashock hazard.
When using probes, keep your fingers behind the
finger guards.
Replace the battery as soon as the low battery
indicator (
B) appears to avoid false readings that can
lead to electric shock and injury.
Adhere to local and national safety codes. Individual
protective equipment must be used to prevent shock
and arc blast injury where hazardous live conductors
are exposed.
Do not hold the Current Probe anywhere beyond the
tactile barrier, see Figure 4.

Before use, inspect the Clamp Meter, voltage probes,
test leads, and accessories for mechanical damage,
and replace if damaged. Look for cracks or missing
plastic. Pay special attention to the insulation
surrounding the connectors.
Avoid working alone when working with live circuits.
Use only insulated test leads and adapters as supplied
with the Clamp Meter, or indicated as suitable for the
Fluke 345 Clamp Meter.
Always connect the Battery Charger/Power Adapter
first to the ac outlet before connecting it to the Clamp
Meter.
Remove all probes, test leads and accessories not in
use.
Do not operate the Clamp Meter around explosive gas
or vapor.
Do not exceed Clamp Meter input voltage or current
ratings.
Do not use exposed metal BNC or banana plug
connectors or insert metal objects into connectors.
WCaution
Do not open the Clamp Meter for cleaning. Do not use
solvents to clean it, and do not immerse it in liquid.
Only trained personnel should perform maintenance work.
Any such work undertaken by unauthorized personnel may
damage the Clamp Meter and will invalidate the warranty.
