Transducer Spacing; Power Considerations - Seametrics jWAVE Instructions Manual

FLOW METER INSTALLATION

Transducer Spacing

Once you entered your parameters in the previous section, the app
automatically computed the proper transducer spacing. This is shown at the
bottom of the main app screen.
The next step is to adjust the transducer spacing on the flow meter, as
follows:
1. Rotate the black knob to unlock the horizontal motion for each
transducer.
2. Move the transducers to the specified transducer spacing by sliding
them along the integrated ruler. Note: It is not necessary to start at
zero on the ruler, so long as the actual spacing is correct.
3. Lock into place using the black knobs. This is important to prevent the
transducer spacing from moving when mounting the flow meter!

Power Considerations

Your jWAVE Flow meter battery has been fully charged at the factory before shipping and is ready to go.* When it's
time to recharge the battery, the app will let you know.
When using the datalogging function and recording for more than 12 hours, the jWAVE must be connected to a power
source, such as a portable USB power bank or a USB power adapter connected to an external power source.
* On a full charge, the jWAVE will have a shelf life of up to five months. It is a good idea to charge the unit for a full five hours if it hasn't been used for
a month or two. On a full charge the meter should operate for up to 12 hours of continuous use. Note that if the battery is flat, the power button LED
will blink rapidly for five seconds and then the meter will turn off.
