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 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 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,

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.

Voltage Measurements
For proper grounding, connect the short ground leads to
the same ground potential, see Figure 8 setup 4. You can
also use test leads for grounding, see Figure 8 setup 5.
See also Grounding Guidelines on page 68.
Ohm, Continuity, Diode, Capacitance Measurements
Use the red shielded test lead from input A and the black
unshielded ground lead from COM (common) for Ohms
(Ω), continuity, diode, and capacitance measurements.
See Figure 7 setup 1.
Current Measurements
Select the probe setting that matches the used current
clamp and its setting, for example, 1 mV/A. See Figure 9
and Measurement Probe Setup.
Temperature Measurements
Use a 1 mV/°C or 1 mV/°F temperature transmitter (not
available in all countries) to get the correct temperature
reading. See Figure 9.
Power Measurements
Select correct probe settings for voltage measurement on
input A and current measurement on input B. See
Figure 7 setup 2.
IntellaSet™ / AutoReading
The AutoReading function uses Fluke IntellaSet™
technology to enable hands-off operation to display meter
readings that correspond with the shape of the waveform.
This function automatically selects the meter readings
that are most often used with the measurement of the
waveform shape. As an example, when the waveform is a
line voltage signal, the V ac + dc and Hz readings show
automatically.
To enable the AutoReading function on input A:
1. Push to open the Scope and Meter button bar.
2. Push 1 to open the MEASURE menu. See
Figure 10.
3. Push 1 to select the AutoReading to ON.
4. Push 4 to select Done and close the menu.
To disable this function, repeat the steps and select the
AutoReading to OFF.
