LIFETIME LIMITED WARRANTY
Each Fluke 20, 70, 80, 170 and 180 Series DMM will be free from defects in material and workmanship for its lifetime. As
used herein, “lifetime” is defined as seven years after Fluke discontinues manufacturing the product, but the warranty period
shall be at least ten years from the date of purchase. This warranty does not cover fuses, disposable batteries, damage
from neglect, misuse, contamination, alteration, accident or abnormal conditions of operation or handling, including failures
caused by use outside of the product’s specifications, or normal wear and tear of mechanical components. This warranty
covers the original purchaser only and is not transferable.
For ten years from the date of purchase, this warranty also covers the LCD. Thereafter, for the lifetime of the DMM, Fluke
will replace the LCD for a fee based on then current component acquisition costs.
To establish original ownership and prove date of purchase, please complete and return the registration card
accompanying the product, or register your product on http://www.fluke.com. Fluke will, at its option, repair at no charge,
replace or refund the purchase price of a defective product purchased through a Fluke authorized sales outlet and at the
applicable international price. Fluke reserves the right to charge for importation costs of repair/replacement parts if the
product purchased in one country is sent for repair elsewhere.
If the product is defective, 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. Fluke will pay return transportation for product repaired or
replaced in-warranty. Before making any non-warranty repair, Fluke will estimate cost and obtain authorization, then
invoice you for repair and return transportation.
THIS WARRANTY IS YOUR ONLY REMEDY. NO OTHER WARRANTIES, SUCH AS FITNESS FOR A PARTICULAR
PURPOSE, ARE EXPRESSED OR IMPLIED. 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. AUTHORIZED RESELLERS ARE NOT AUTHORIZED TO EXTEND ANY DIFFERENT
WARRANTY ON FLUKE’S BEHALF. Since some states do not allow the exclusion or limitation of an implied warranty or
of incidental or consequential damages, this limitation of liability may not apply to you. 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.

- The following performance tests will ensure that the meter is in proper operating condition and will check the accuracy of each meter function against its specifications to perform the tests you will need a fluke 5520a calibrator or equipment meeting the minimum specification given in table 1
- Testing the display push down the
- Testing the display
- Performance tests
- If the meter fails any of these tests it needs calibration adjustment or repair
- Current terminal sensing test
- Button and simultaneously turn the meter on compare the display with the example in figure 4 check all segments for clarity and contrast
- Backlight test
- Verification of the ir communication port
- Testing temperature
- Keypad test
- Turn the rotary switch to the function listed in each step
- Testing voltage current resistance capacitance and diode functions to verify the accuracy of meter functions do the following
- Testing voltage current resistance capacitance and diode functions
- Repeat steps 2 through 4 for the remaining inputs shown in table 4
- If the display reading falls outside of the range shown in table 4 the meter does not meet specification
- Connect the calibrator to the v and com inputs on the meter
- Compare the reading on the meter display with the display reading in table 4
- Apply the input from the steps listed in table 4
- True rms multimeter performance tests
- Keypad interface
- Calibration
- General procedure
- Calibration inputs
- When you replace the u10 eeprom you must also re enter the serial number and model number for the meter see reprogramming meter serial number and model number section
- True rms multimeter calibration
- Temperature calibration need only be performed if one of the following components are replaced during the course of repair u4 a d chip u10 eeprom or u100 reference junction sensor temperature is calibrated by making an external temperature measurement and entering the result into the instrument for calculation of the calibration constant the calibration constant is then stored in calibration memory this is done using the serial interface see temperature calibration section
- Special requirements dc mv calibration will affect the calibration of all other functions therefore the dc mv function must be calibrated before calibrating any other function similarly ac mv must be calibrated before any ac function but after dc mv the remaining functions may be calibrated in any order
- Special requirements
- Note the column indicating time to settle does not include calibrator settling time
