RW Onboard Load Scale helps you avoid overloading and increase productivity. Its high-accuracy strain sensors measure weight and send the data to an easy-to-read display.

The mobile app extends the scale's functionality, allowing you to monitor weight remotely, save and share weigh tickets, and get job site updates.

DO NOT connect directly to a baery or any constant power source, gauge should be connected to a switched

source so that it can be disconnected from power when not in use. Most users connect the power to vehicle

marker lights or the AUX/ABS wire.

Electrical connecons MUST be insulated, see Appendix B for instrucons.

If you need to change the number of strain sensors at any point, follow these steps:

1. Turn oﬀ the scale

2. Press and hold the C HIGH buon and the MENU buon, press the POWER buon, then release all 3

3. Use the UP arrow buon to change the number of strain sensors to the number desired

4. Turn oﬀ the scale to save seng

Please note that by changing the number of strain sensors the scale recognizes, all calibraon data will be LOST
