Key instructions:
AUTO MPPT DETECTION:
When pressing the AUTO test button, the instrument automatically adjusts the test interval time according to the current power value and refreshes the digital display.
 
For example: when the power of photovoltaic panel is 100W, refresh once every 5S; when the power is 300W, refresh once every 15s.
MANUAL MPPT DETECTION:
When pressing the manual test button, the instrument starts a scan of the maximum power point and refreshes the digital display.
