Encoder buttons, menu, and screen
Use the older Vitruve Encoder's power switch and two buttons, including touch-sensitive ones, open its Menu screen, and read the rep data on its OLED display.
This page covers the controls of the older Vitruve Encoder. Vitruve Force uses membrane buttons and a larger screen; see Vitruve Force overview.
The encoder has a power switch on the left side of the screen and two buttons below the screen.
Power switch
Use the switch on the left side of the screen to turn the encoder on and off.
When it starts in Bluetooth mode and is ready, the screen shows the VITRUVE logo, then BTXXX (its Bluetooth ID), then GO. If it shows WIFIXXX instead, it is in Wi-Fi mode. See The encoder does not appear in Bluetooth.
Left button
The left button below the screen has two uses:
- Switch between Bluetooth and Wi-Fi mode. Keep the encoder in Bluetooth mode for the current app. The switching steps are in Encoder hardware troubleshooting.
- Go to the previous rep. After at least two reps, press it to view the previous rep on the screen. If you press it while viewing the first rep, the reps on the screen are reset.
Right button
The right button below the screen also has two uses:
- Switch between UP and DOWN mode. UP is the default and records concentric reps. DOWN is the face-down mode. If the encoder records eccentric reps instead of concentric ones, it is in DOWN mode. See The encoder records eccentric reps.
- Go to the next rep. Press it to view the next rep on the screen. If you press it while viewing the last rep, the screen is reset.
Touch-sensitive buttons
Some encoders have flat, touch-sensitive buttons, often in a silver finish, instead of buttons that click. They do not move when you touch them, so a button that feels stuck may be working normally. Touch the button area lightly; pressing harder does not help.
The mode changes work the same way as on clicking buttons:
- Power on the encoder.
- Pull the string by hand for exactly three reps. The buttons respond to a long touch only after these reps.
- Touch and hold the right button area for eight seconds to switch between UP and DOWN, or the left button area to switch between Bluetooth and Wi-Fi.
If a button is physically loose, cracked, or stuck in its hole, do not open the unit. Report it as a faulty device.
Menu screen
Press both buttons at the same time to open the Menu screen. It shows:
| Item | What it tells you |
|---|---|
| BT ID | The Bluetooth name. Use it to find the right unit in the app when several encoders are nearby. It also appears on screen when you turn the encoder on. |
| Detect Mode | UP (default) or DOWN (face-down mode). |
| Firmware Version | The firmware installed on the encoder. |
| Encoder ID | A unique ID in the format XX:XX:XX:XX:XX:XX. Support may ask for it when troubleshooting your unit. |
Note the BT ID and Encoder ID before you contact support about a hardware problem.
OLED screen during reps
While you train, the screen shows the current rep:
| Position | Data |
|---|---|
| Top right | Number of reps completed, and which rep is on screen |
| Center | Mean velocity of the rep, in m/s |
| Bottom left | Distance, in cm |
| Bottom right | Peak velocity, in m/s |
The app can show different metrics, such as mean propulsive velocity, so its numbers may differ from the screen's mean velocity. See Encoder reliability and calculated metrics.
Connect and place
Put the encoder in Bluetooth mode, pair it with the app, fix it to a safe magnetic spot, and run several encoders on one tablet.
Reliability and metrics
Why Vitruve uses a linear position transducer, what the validation research found, and how each velocity, force, power, and fatigue metric is defined.
