4. Trigger . Note that the greater than (>) symbol changes to a (:) colon. Trigger to change
the second line to [Yes] (as shown in the right-hand figure above). Trigger  to clear all
Dynamic Memory.
5. To restore operation, create a new Site Setup and then re-select any Meter Facilities items
(e.g., RS-232 setup parameters) that you may have edited originally.
6.8.2 SYSTEM RESET USING THE RS-232 INTERFACE
The FUH1010PVX flow computer also allows you to perform a system reset via its RS-232 interface. The
following instructions require the flow computer to be connected serially to a PC. Refer to paragraph
2.7.1 for details on how to set up an RS-232 interface with a PC.
To clear Active Memory using the RS-232 Interface:
1. Turn off power (if it is currently on). Turn power on. As soon as you apply power type the @
character three times. The prompt: [Clr Active Memory? No] appears at the top of the
screen.
2. Press the <Right Arrow> and then the <Down Arrow> to switch the option list to [Clr Active
Memory? Yes] . Press <ENT> to clear all Active Site Data (but not saved Site Setups).
3. To restore operation, press <MENU> to access the Installation Menu. Create a new Site Setup
or recall a stored Site Setup. Re-select any Meter Facilities items (e.g., RS-232 setup param-
eters).
To clear ALL Dynamic Memory using the RS-232 Interface:
1. Turn off power (if it is currently on).
2. Turn power on. As soon as you apply power type the @ character three times. 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] .
3. Press the <Right Arrow> and then the <Down Arrow> to switch the option list to [Clr Saved
Data? Yes] . Press <ENT> to clear all Dynamic Memory.
4. 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).
6.9 TROUBLESHOOTING WITH TRANSDUCER TEST BLOCKS
To resolve an apparent system malfunction, you have to determine whether the problem is due to
equipment failure or an application condition. Our 1012 and 996 Transducer Test Blocks allow you to
bench test the FUH1010PVX, transducers and their cables. If the system operates properly using the test
block, then focus on application conditions as the source of the problem. Series A and B 1011 transduc-
ers use the 1012TB-1 Test Block and series C and D use the 1012TB-2 Test Block. At the present time,
neither one support the 1011 High Precision transducers.
The 996PSP-Pipe Simulator allows you test a FUS1010 series meter and 991 transducers from size 0 to
size 3. Note that although the FUS1010 meter operates with our 991 size 4 and 5 transducers, testing
of these sizes with a FUS1010 meter is not currently supported.
