Switch between secured and unsecured mode using the

switching utility

The switching utility must be installed on your PC. The switching utility is available from
the Micro Motion web site:

.

Before switching to unsecured mode, ensure that you will be able to switch back to
secured mode. Because switching to unsecured mode requires breaking the physical seal,
switching back to secured mode may require a site visit from a certified Weights &
Measures inspector and reinstallation of the physical seal.

Ensure that the wiring is in place for a service port connection. You may need to break the
seal and remove the clamp.
