OPERATION
Making a Recording
• Connect to the meter with the jWAVE App.
• Tap the Data Logging button to access the data logger
features.
• Using the slider bar in the app's data logger setup view, set the
recording time. (See Explanation of Recording Times on the
next page.)
• Tap "Rec" to start the recording. Data will start recording
on the meter. You can disconnect the mobile app during
recording. The meter will turn off when done to save power,
unless still connected to the app.
• To stop recording prior to completing the time period, connect
the jWAVE App to the meter, tap the Data Logging button, and
tap "Stop."
The status of the data logger is indicated by the color and text of
the data logger setup button, located in the measurement view. If
data logger is active, the button is outlined in red, shows a red disk
drive, and displays "in progress." If the data logger is completed,
the button is outlined in green, shows a green disk drive, and
"complete." The data logger setup view also displays the remaining
recording time for conveniently checking progress of data logging.
Uploading Data
Data is stored on the flow meter and may be retrieved at any
time. To upload data, the data logger must be either complete or
stopped and the app must be connected to the flow meter. Data is
uploaded using the "share" button located to the right of the "Rec"
button. Uploading the maximum sized data set may take up to 5 1/2
minutes.
iOS users: If you want to quickly review your data at any time, tap
the "share" button, and then tap Quick Look. This displays the data
log in a spreadsheet for immediate viewing on your mobile device.
Sharing Data
You only need to upload the data log once from jWAVE. Once the
data is uploaded, it may be shared any number of times without
additional uploading, until a new data log is started. Tap the "share"
button to share the data by a number of methods, email, text,
AirDrop, Google Drive, etc., depending on what is available on
your mobile device. Shared data is formatted in a CSV file (comma
delimited file). The file name is unique and contains both the date
and time that the data log was started as well as the location
name. Setup information such as the date and time the data log
was started, the number of samples, sampling period, and location
name are located at the top of the data file. The data is arranged in
rows, where each row contains a single flow measurement including
sample number, time stamp, flow rate, velocity, volume, and quality.
The data file can be viewed or printed as a text file or formatted
using most spreadsheet and database programs, such as Microsoft
Excel or Access.
