The WeighIn module is a specialized part of the JudoManager software designed for entering and managing athlete weigh-ins before the start of a competition. It allows for fast, accurate, and organized recording of athletes' body weight and enables category adjustments if the recorded weight differs from the registered one. The module is optimized for use with a digital scale and barcode scanner, which speeds up the weigh-in process and reduces the risk of errors.
Tasks in the WeighIn Module
1. Synchronize
This function retrieves the current state of the competition (registrations, weights, etc.) into the WeighIn application.
- if the device is set as a Local location, the data is pulled from the server computer running the JudoManager Desktop application.
- if the device is set as a Remote location, the data is fetched from the cloud database.
2. Push weights
This function sends the recorded weights back to the main system – either to the server computer (in a local setup) or to the cloud (in a remote setup).
3. Delete Weights
If any errors occur during the weigh-in, you can delete the weight at any time and repeat the process. This feature is especially useful for correcting mistakes or reweighing an athlete.
Options in the WeighIn Module
- Settings - used to set up the WeighIn module. Read in detail WeighIn settings article.
- Test - This option allows you to test the connection between your scale and the application. When you press the Test button, a WeighIn test window will open with placeholder user data. Step on the scale and check whether the weight is automatically transferred to the weight input field. If the message "No scale connected" appears in red, please ensure that the scale is properly connected to the computer and to a power source, and that the correct settings are applied. It is strongly recommended to test both the scale and the barcode reader before starting the official weigh-in process.
Weigh-in process
The weigh-in can be performed for each registered athlete. The list of registered athletes is displayed in the main view of the WeighIn module. Rows marked in white indicate unweighed athletes, while rows marked in green indicate athletes who have already been weighed.
Athletes can be found manually in the list or quickly accessed by scanning their barcode. You can scan either a
QR code from the accreditation card or a
barcode representing the athlete. These barcodes are generated and printed from the
JudoManager Desktop application or from
admin.judomanager.com, where clubs register their athletes for the competition.
The weigh-in is conducted through the WeighIn window, which opens automatically when a barcode is scanned or when you double-click on an unweighed athlete in the list. Once the window is open, the athlete can step on the scale. If the scale is properly connected, the weight is automatically transferred to the weight input field. If the scale is not connected, the weight can be manually read from the device and entered by typing it in.
After the weight is entered, the system automatically detects whether the athlete is too light, too heavy, or within the weight range of their registered category. Based on this result, the system displays available options such as moving the athlete to a higher or lower category, or accepting the athlete in their current category regardless of the weight mismatch.
If the athlete is within the allowed weight range and above the limit of lighter categories, only the Confirm button will be shown. If the athlete is over the limit, you will have the option to move them up, remove them from the competition, or accept them anyway. If the athlete is under the limit of another lighter category, the system will offer the option to move them to that lighter category.
Once the athlete has been weighed, their row will be highlighted in green and they will be moved from the "Registered" section to the "Weighed" section in the tree structure sidebar.

We recommend using barcode scanners that can read both QR codes and traditional barcodes. It is important that the scanner supports the carriage return function, as it must be able to automatically send the "Enter" command after scanning. This ensures that the WeighIn window opens immediately after a code is scanned, without requiring additional manual input.
