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, 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 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.

Required Equipment

The equipment listed in Table 2 is necessary to do the calibration and test for the
712B. The equipment listed in Table 3 is necessary to do the calibration and test
for the 714B.

Note

Fluke 5522A and Fluke 8508A need an 8-hour warmup period
before the calibration starts. The 5522A needs to zero all the
functions weekly and zero Ohms output function every day. The
8508A needs to zero the dc V measurement function, the 4-Wire
Ohms measurement function and the DCI measurement function.

Use 8508A to Adjust the 5522A Output

Adjust mV Source

To use the 8508A to calibrate the 5522A output:

1. Connect the voltage output terminals of the 5522A with the voltage input

connectors of the 8508A via the pure copper cables.

2. Set the resolution of DCV measurement mode to 7 1/2-digits or above.

3. Adjust the output of the 5522A until the reading of the 8508A is -10 mV

±0.2 μV, and record the voltage setting of the 5522A (=Voltage

-10mV

Setting).

4. Adjust the output of the 5522A until the reading of the 8508A is 75 mV

±0.2 μV, and record the voltage setting of the 5522A (=Voltage

Setting).

Note

The two voltage setting records are used to calibrate the UUT.

To calibrate the 714B mV Source function:

1. Connect the 714B TC mini plug and the 8508A with pure copper cables, as

shown in Figure 15.
