Passcodes and Menu Selection
To configure and carry out certain functions in an RHE26/27 transmitter, it is necessary to enter
a predetermined passcode. Passcodes protect configuration setup and prevent inadvertent
changes to the flow meter operating condition. There are two different access levels with
separate passcodes: “USER” and “SERVICE”. The USER level accesses those functions that relate
to the operation of the flow meter on a day to day basis i.e. zeroing and totalizer reset. The
SERVICE level allows access to configuration and setup functions such as I/O ranging and
calibration.
When needed, the screen will prompt for a passcode. Passcodes are entered using the NEXT and
ENTER buttons. Once entry is complete, the entire passcode will flash. Press ENTER again to
enter the menu. If the passcode supplied is incorrect, the cursor will return to the leftmost
character of the passcode for re-entry.
Factory default passcodes are shown in Table 8. The USER level passcode can be changed by
accessing the “Service Login” menu.
