LIMITED WARRANTY & 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 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 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 or send the product, with a description of the difficulty, postage and insurance prepaid (FOB Destination), to the nearest Fluke authorized service center. 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 the failure was caused by misuse, alteration, accident or abnormal condition of operation or handling, 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, WHETHER ARISING FROM BREACH OF WARRANTY OR BASED ON CONTRACT, TORT, RELIANCE OR ANY OTHER 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 of competent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

Contents (continued)
AC Power Source
The instrument is intended to operate from an ac power source that will not apply more than 264v ac rms between the supply conductors or between either supply conductor and ground. A protective ground connection by way of the grounding conductor in the power cord is required for safe operation.
DC Power Source
The instrument may also be operated from a 9 to 16v dc power source when either the rear panel ground binding post or the power cord grounding conductor is properly connected.
Use the Proper Fuse
To avoid fire hazard, use only a fuse identical in type, voltage rating, and current rating as specified on the rear panel fuse rating label.
Grounding the Instrument
The instrument utilizes controlled overvoltage techniques that require the instrument to be grounded whenever normal mode or common mode ac voltages or transient voltages may occur. The enclosure must be grounded through the grounding conductor of the power cord, or if operated on battery with the power cord unplugged, through the rear panel ground binding post.
Use the Proper Power Cord
Use only the power cord and connector appropriate for the voltage and plug configuration in your country.
Use only a power cord that is in good condition.
Refer cord and connector changes to qualified service personnel.
Do Not Operate in Explosive Atmospheres
To avoid explosion, do not operate the instrument in an atmosphere of explosive gas.
Do Not Remove Cover
To avoid personal injury or death, do not remove the instrument cover. Do not operate the instrument without the cover properly installed. Normal calibration is accomplished with the cover closed, and there are no user-serviceable parts inside the instrument, so there is no need for the operator to ever remove the cover. Access procedures and the warnings for such procedures are contained in the service manual. Service procedures are for qualified service personnel only.
Do Not Attempt to Operate if Protection may be Impaired
If the instrument appears damaged or operates abnormally, protection may be impaired. Do not attempt to operate it. When in doubt, have the instrument serviced.

Introduction
Note
This manual contains information and warnings that must be followed to ensure safe operation and keep the instrument in safe condition.
Data Bucket operation and operational features can be understood in about ten minutes by completing the following procedure. Prior to staring the procedure, connect the instrument to a power source (see Chapter 1) and connect the supplied test leads to the front panel jacks (Channel 0). Some steps terminate when you press the Ckey instead of the Ekey because the completed step is beyond the scope of this quick tour. However, all steps contain a figure reference in brackets [] for additional information. For example, the first step of applying power refers to [Figure 2-2], which describes three other ways of applying power (Configuration-Reset, Display-Hold, and Temperature-Toggle). Therefore, this procedure may be used for a quick instrument familiarization or as a basis for instrument applications.
It is assumed that the instrument is being powered for the first time or a configurationreset procedure cleared the instrument of configuration data. To apply a configurationreset to the instrument, hold down the Ckey when turning on the power and keep holding until the meter “beeps” in acknowledgment.

Setting Mx+B Scaling. Press the Mx+B key to open the Mx+B menu. Up/down and left/right arrow keys select the digits for the first parameter
(M) (default +001.00). The effect of Mx+B scaling is to take a measurement (x) and modify it by multiplying the measurement with M and then adding an offset B (configured after M is set). For example, Mx+B=+1.5x+25 applied to a measurement of 20.000 would display 1.5(20.000) + 25 = 55.000. Press CANCL to exit. [Figure 2-14]
Selecting the Measurement Rate. Press the SHIFT key, release, then press the Right Arrow key to open the RATE menu. During the measurement portion of the scan interval, the measurement rate can be FASt (Fast) or SLO (Slow). The slow rate gives full 5-digit measurement resolution, while the fast rate gives only 4-digit resolution. The advantage of a fast measurement rate is more readings during continuous scanning or low scan intervals. Press CANCL to exit. [Figure 2-12]
