To Clear All Dynamic Memory Using the RS-232 Interface:

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! Also, 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 our technical
service department before continuing with this procedure. If you choose to con-
tinue, 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.

1. Turn off power (if it is currently on).

2. Turn the power on. As soon as you apply power, type the @ character three times.

The prompt:

[Clr Active Memory?]

appears at the top of the screen. Press the <Down Arrow>.

Note that the prompt switches to

[Clr Saved Data? No]

3. Press the <Right Arrow> and then the <Down Arrow> to switch the option list to:

[Clr Saved Data? Yes]

4. Press <ENT> to clear all Saved Site Data, Datalogger Data, user created Pipe Data and Transducer

Data.

5. To restore operation, press <MENU> to access the Installation Menu. Create a new site setup or

recall a stored site setup. Reselect any Meter Facilities items (e.g., RS-232 setup parameters).

RESET PROCEDURE FOR BLIND SYSTEMS

1010N Blind systems allow you to perform a system reset via the RS-232 interface. The following
instructions require the flowmeter to be connected serially to a PC.

NOTE: Custom RS-232 settings for baud rate, parity and data bits may not be preserved. There-

fore, be prepared to set your communications program back to the default (9600, Odd,
7) settings.
