10.2 Switch between secured and unsecured mode
You must switch to unsecured mode to change the transmitter configuration or perform
many administrative tasks. You must switch back to secured mode in order to meet
Weights & Measures requirements for process measurement.
You must use one of the following tools to switch modes:
• ProLink II
• ProLink III
• The Custody Transfer “switching” utility. The switching utility is free, and is available
from the Micro Motion web site: www.micromotion.com/softwaredownloads.
Operate the transmitter with the Weights & Measures application
