Calibrate with Crimpdeq App

Prerequisites

• Crimpdeq app on your platform:
  • Web version (no installation): Crimpdeq web app
    • Not all browsers support WebBluetooth. Check browser compatibility.
  • Native builds from the latest release: crimpdeq-app/releases/latest
    • Android: crimpdeq-app-v<x.y.z>.apk
    • macOS: crimpdeq-app-v<x.y.z>-macos.zip
    • Windows: crimpdeq-app-v<x.y.z>-windows.zip
    • Linux: crimpdeq-app-v<x.y.z>-linux.zip
• A stable mounting point so the device hangs freely and remains still
• At least one known weight (ideally near your typical maximum load)

Calibration Steps

1. Connect to your Crimpdeq

   1. Launch the Crimpdeq app and grant permission to access device location (required for Bluetooth).
   2. Tap Scan to pair with your device.
   3. Once connected, the app shows device info (firmware version, battery, and current calibration).

2. Add calibration points

   1. Open the Calibration tab.
   2. For each point:
   • Hang the corresponding load on the device (or leave it empty for zero).
   • Enter the weight value in the app and tap Add Calibration Point.
   • Recommended: Add at least 2 points—zero (nothing hanging) and full scale (the maximum weight you expect to measure). The device supports up to 20 calibration points for finer accuracy.

3. Check the result

   1. After adding at least 2 points, the app displays the current calibration curve. Confirm it matches your expectations.

   

Adding more calibration points (up to 20) improves measurement accuracy across the full load range.
