Unpacking the Meter
Open the Multimeter box. Inside will be found a 189II/AN Digital Multimeter, one set of
test leads, a Product Manuals CD, a 189II/AN Users Manual, and a 189II/AN Service
Manual. Remove the Meter from its plastic wrapping.
Inspection
Inspect all contents for any visible shipping damage. Look for scratches or any other
damage. If the Meter is damaged, contact Fluke immediately using the contact
information listed in the “Contacting Fluke” section earlier in this manual. If it is
necessary to return the Meter, place it in its original packaging and return.
