Assembly & Setup

Single-plate setup

1. Place the non-slip mat on a rigid surface (concrete or wooden platform recommended)
2. Set the ZPlate on the mat with the arrow facing toward the athlete
3. Connect to the ZForce app (see Quick Start)

Dual-plate setup (bilateral testing)

For asymmetry analysis (L vs R), two ZPlates are used simultaneously.

1. Place both plates side by side, separated by 0–2 cm
2. Label: the left plate is ZPlate-L, right is ZPlate-R
3. In the ZForce app, tap Connect Device and connect both — the app identifies them by BLE name
4. The app pairs samples using the sequence counter, not timestamps, so both plates must be connected before starting a test

Caution

Always connect both plates before taring. Tare is a firmware command — never auto-tared by the app on test start.

Load cells

The ZPlate uses 4 load cells (one per corner), each with its own 24-bit ADC channel. Individual channel data is streamed and summed in the app. The load cell type is DYX-301-100.

Firmware

The ESP32-C6 firmware version is shown in the ZForce app under Device Info. OTA (over-the-air) firmware updates are available via the Hootuo Hub Firmware tab.

Enclosure

The enclosure is anodised aluminium. Do not expose to standing water. Clean with a dry or slightly damp cloth.
