Procedure to clear Active memory only:

No] appears at the top of the screen.

option list to [Clr Active Memory? Yes]. Press <ENT> to clear all Active Site Data (but not saved
Site Setups).

Procedure to clear ALL Dynamic Memory:

2. Press the [F4] key and keep it pressed while you turn on power. The prompt: [Clr Active Memory?
No] appears at the top of the screen. Press the Down Arrow. Note that the prompt switches to [Clr
Saved Data? No].

CAUTION: Before proceeding further it is essential to understand that this function elimi-
nates
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 addition, 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 recom-
mend that you consult technical service before continuing with this proce-
dure. Be aware that you will have to create a new Site Setup, re-enter all site
specific parameters including pipe or transducer tables, plus all desired Meter
Facilities entries.
4. Press <ENT> to clear all Dynamic Memory.
5. Create a Site Setup before attempting to access other menu items.
6. To restore operation, press <MENU> to access the installation menu. Create a new site setup and
complete the installation procedure.
7. Re-select desired Meter Facilities items (e.g., RS-232 setup parameters).
