5) Device setup

The MG4800 has 3 modes: Real Mode, Max Mode, and Target Mode.

In Real Mode, the MG4800 will dynamically display the force exerted, which changes in real time as the user squeezes and lets go.

In Max Mode, the MG4800 will record the maximum force.

In Target Mode, a target force will be set (ex: 20 kg), and the MG4800 will record how many measurements exceeded this target, as well as the average of the last two results.

To transfer measurement results, the device must be in Target Mode. Press [Set] key to enter Target Mode. By default, target is 20 kg - you can press [Mode] key to increase (press and hold to increase faster). Press [Set] key to confirm target.

Begin using MG4800. Device will automatically record every result that exceeds target.

After measurement is complete, press [Power/Zero] key to transfer results to Charder Connect.

Press [Save] key to save results, or [Clear] key to discard. You can press "Right" or "Left" on the screen to specify which hand was used for each measurement.
