5. Bedryfsinstruksies

5.1 Connecting to the Mobile App

1. Open the "PQWT Water Finder" software on your mobile device.
2. Allow Bluetooth access when prompted.
3. The app will scan for devices. Select "PQWT-M100" from the scan list to connect. The signal name defaults to PQWT-M100.
4. Once connected, the app interface will show "Connected".

5.2 Performing a Profile Opname

After preparation, you can begin the measurement process:

1. In the app, click "Settings".
2. Choose "Profile Survey" mode.
3. Set the measurement line ("Lines") to "1". The gain is set to "0" by default; no need to set it again. Click "OK".
4. Wire the cable and use a 50-meter tape measure to pull the tape in a straight line at the location where detection is needed. Mark the starting point.
5. Before measurement, put two connected electrodes (M and N) together.
6. Press and hold the "TEST" line detection button on the host. A green test light indicates the line is normal.
7. Insert the M pole near the end of the host machine into the 0m position of the tape measure.
8. Insert the N pole at the other end into the 10m position of the tape measure.
9. Click the "Record" button in the app to measure the first point.
10. After data measurement is completed, the mobile phone interface will prompt "Record completed" with a sound.
11. Move the two electrodes one meter away at the same time. Click the "Record" button to perform the second point of data acquisition. Repeat this process for subsequent points.
12. Each measurement point is at the midpoint of the two electrodes. For example, the first point is at the 5-meter tape position (midpoint of 0m and 10m).
