§4.13 How to use the built-in data logger
1) The built-in logger has a space of 24 KB of memory, which will hold about 2,000 lines of data.
2) Use window L10 to start logging; this can be accessed using the following series of keys: LOG

Log Items. This will turn on or off the logger as well as select the items to be logged.
3) Use windows L11, L12, L13 to set up the starting time, time interval, and logging duration,
respectively. All of these windows can be accessed using the following series of keys: LOG

Schedule.
4) Use window L20 to save the logged data. The data can be stored in a logger buffer. Alternatively,
the data can be directed to the RS-232C interface without being stored in the logger buffer. This
window can be accessed using the following series of keys: LOG

Save To.
5) Use window L30 to view saved data in the logger buffer. This window can be accessed using the
following series of keys: LOG

View Log.
6) Use window L40 to clear any unwanted logging data remaining in the RS-232C interface and in the
logger buffer. This window can be accessed using the following series of keys: LOG

Clear Log.
7) The data stored in the data logger can be downloaded to any PC with the Windows Hyper Terminal
program. Another option is Spire Metering’s StufManager ™ software. StufManager ™ will also
help the user set up the data logger. Please visit the following website for more details:

§4.14 How to use the Frequency Output
All RH40 Series Flow Meters have a Frequency Output functionality. The signal for each device
represents its flow rate for the purpose of communicating with other devices. The emitted frequency
output signal is designed to connect with other instruments.
The Frequency Output is completely user-configurable. Usually, three parameters are configured:
1)
Enter the frequency range in the “Freq Range” window as follows:
M

2) Enter the lower limit of flow rate in the “Freq Min” window as follows:
