options ordered are included with the shipment by checking the packing list 
included with the shipment.

Original packaging
Containers and materials identical to those used in the factory packaging are 
available through Keysight Technologies office. If the multimeter is being returned 
to Keysight Technologies for servicing, attach a tag indicating the type of service 
required, return address, model number, and serial number. Also mark the 
container FRAGILE to assure careful handling. In any correspondence, refer to the 
multimeter by model number and serial number.

the damaged shipping materials (if any) for inspection by the carrier and 
Keysight representative. If required, you can find a list of Keysight Sales and 
Service Offices on the last page of this guide.
