2. Handling Cautions
This chapter provides important information on how
to handle the transmitter. Read this carefully before
using the transmitter.
EJX Series transmitters are thoroughly tested at the
factory before shipment. When taking delivery of an
instrument, visually check them to make sure that
no damage occurred during shipment.
Also check that all transmitter mounting hardware
showningure2.1isincluded.Ifthetransmitter
is ordered without the process connector, the
transmitter mounting hardware will not be included.
After checking the transmitter, carefully repack it in
its box and keep it there until you are ready to install
it.
