CAUTION: Before proceeding further it is essential to understand that this function
eliminates
ALL data stored in RAM. This means that all saved site setups
including the site data of a flow-calibrated site will be erased! In addi-
tion, the entire Datalogger file plus any custom factory or user-created
pipe or transducer tables will be eliminated. The impact of this is such
that we strongly recommend that you consult technical service before con-
tinuing with this procedure. Be aware that you will have to create a new
Site Setup, re-enter all site specific parameters including pipe or trans-
ducer tables, plus all desired Meter Facilities entries.
To clear all Dynamic Memory press <ENT>.
Create a Site Setup before attempting to access other menu items.
To restore operation, press <MENU> to access the installation menu. Create a new
site setup and complete the installation procedure.
Re-select desired Meter Facilities items (e.g., RS-232 setup parameters).
