control function

Staged loading can be set on the software, and staged loading can be performed automatically.

Manual loading: input power and power factor, that is, loading according to the specified value.

Preset loading: Enter the relevant parameters of the generator set, you can select preset ratios such as 0%, 25%, 50%, 75%, 100% to 110%, and automatically calculate the corresponding power to achieve fast loading.

Automatic loading: The power and duration of multiple loading stages can be set during testing, and stage testing can be performed automatically. Pause at any time during loading, or skip to the next stage

Test function
