Don't know how to pick up data from UNIT-T (UTD2052CL)

Hello everyone,
recently i have brought a oscilloscope for making a test for Solar Panel (anti-islanding test)
mainly i want to know test if i turn off the main electrical supply, the inverter will turn off within 200ms.
so i get the current in CH-1 and Voltage in Ch-2, and i use "Utility" button and record the waveform.
sadly that i can just get the page with full of waveform and none of waveform but the instantaneous changes.
how can i get the instantaneous changes, that i can know the invertor is turned off within 200ms
Thanks all guys!!!!!
