Logging Data
The term data logging denotes the recording (saving)
of measured value data on the internal SD Memory
Card. All measurement data like time and date, flow,
velocity, totalizer and thermal output, heat quantity and
temperatures (when using temperature sensors). If
temperature sensors should not be in use these values
are shown as “0” in the log files. The data is stored in a
text file (*.txt) which allows easy and quick export into
office software like Microsoft
®
Excel or similar.
Time-Controlled Data Logging
Your UFM supports time controlled data logging to the
internal SD memory card.
i
The time controlled data logging uses the in-
ternal system time which is set by user. Make
sure the system time is correct.
In the primary measuring window “Flow 1”:
Select
“SETUP” -> “CMPL SETUP” -> “Data logger”
Navigate to the Data logger parameters field and con
-
firm your entry with “NEXT”. Assign a file name (min.
4 characters). Use the arrow keys to select the letters,
or delete a letter by means of “DEL”. Accept the letter
with “ENTER”. Select “DONE” and press “ENTER” to
conclude data input
Continuous Data Logging:
Example: You want to log the data generated from
May 25, 20YY, 3:00 PM to May 26, 20YY, 4:00 PM.
The data is logged at cyclic intervals of 60 seconds to
the SD Card.
25.05.20YY 26.05.20YY
27.05.20YY
Start 15:00
Stop 16:00
• Enter the start date May 25, 20YY
• Enter the start time 3:00 PM
• Enter the duration in 001:01:00:00 format
• Enter the interval in 00:00:60 format
i
The data logger does not average values
over the cycling period. The current values
are always stored. If you choose interval of 10
seconds the current values each 10 seconds
are stored (not the average over last 10 sec).
To delete or to rename existing log files please con
-
nect your UFM to your PC using the USB cable. Then
access the log files directly at the SD card.
Message “LOG ACTIVE” is being shown at the display
while data logging is going on. If there is no data log-
ging display shows “LOG INACTIVE.”
