IF YOU ARE USING AVIO FOR ROWING, you will need to link the Avio app on your phone to an oar. you should calibrate the sensor on that oar before use.
Specifically, if the oar is not calibrated properly it is likely to measure force going through the oar, but you will not be able to compare one oar with another, nor will you collect completely accurate readings from the sensor.
In theory, once calibrated, there should not be any need to re-calibrate the oar, but some prefer to repeat the process periodically, especially if:
- The oar is being used in climates where the temperature is significantly different to the one at which it was calibrated.
- It has been a long time (12 months) since the last calibration.
TO CALIBRATE A NEW OAR, YOU WILL NEED:
A 10kg weight. These can also be purchased from Amazon or we can supply them upon request.
A wire or rope to attach the weight to the oar. We use three 100cm ‘safety cables’ designed for lighting gantries in theaters because of their useful carabina style ‘easy to attach’ attachment at one end, but any piece of rope will do.
A flat surface to rest the ends of the oar on whilst it is calibrated.
Step-by-step Guide – Preparing for Calibration
PREPARING FOR CALIBRATION
1) Place the oar on a flat surface with enough room underneath the oar to hang the 10kg weight.
2) Ensure that the face of the oar is facing downwards, ie the sensor should the be on the topmost side of the oar
3) Ensure Bluetooth is switched on
4) Open the RowSense app
5) Make sure your Avio sensor is attached to the oar and give it a tap to wake the PowerSense
7) The RowSense app constantly is searching for new devices, so your sensor should show up.
8) Drag and drop your sensor into the position you would like, press back and your sensor will begin reading immediately.
9) Press back and click the name of the oar you would like to calibrate, press the graph, then press connect.
10) Press the spanner/settings icon in the bottom right. It will come up with “10kg Calibration. Are you sure?”
Step 1 –
Place the oar on a flat surface with enough room underneath the oar to hang the 10kg weight.
Step 2 –
Ensure that the face of the oar is facing downwards, ie. the sensor should be on the topmost side of the oar.
Step 3 –
Ensure that you have the Avio RowSense app downloaded on your iOS device and the Bluetooth on that device is switched on, you will need this to connect to the Avio PowerSense.
Step 5 –
Make sure your Avio sensor is attached to the oar and give it a tap to wake the PowerSense
Step-by-Step Guide – Calibrating the Oar
Now that your oar and PowerSense is set up to calibrate, next up is the actual calibration of the PowerSense!
Make sure your Avio RowSense app is open for this and Bluetooth is switched on!
Step 1 – Navigate
Once you’ve opened the RowSense app, navigate to the 3rd icon on the bottom of the screen.
Step 2 – Find your sensor(s)
Avio PowerSense, (once tapped to be woke) is always searching. Drag your sensor into the position you would like for it to be in the boat.
Step 3 – Back
Once placing your rowers in their spaces, press back.
Step 4 – Rowers name
Once you’ve pressed back, you will see the page on the phone opposite. Click the name of the rower that you would like to calibrate.
Step 5 – Graph
Once you have clicked on the rowers name, you will come to this page. Click the graph.
Step 6 – Connect
Although you are already connected to the PowerSense, you will need to manually connect again using this stage
Step 7 – Spanner
Once connected, you will need to press the spanner icon in the bottom right of the screen.
Step 8 – 10KG Calibration
Finally, before you press yes, make sure you double check that the 10kg weight is hanging freely from the oar. The screen will show the message: “10kg calibration. Are you sure” And press yes.
