1. Setting function
a. Mode switching: After the boot is complete, press \"Settings \" key, \"TEST \" appears, press \"Settings\" key
again, 0001 mode appears, use \"Keys can choose different modes. As shown in the figure below:
0001 Standard test mode (factory default mode): In this mode, three states can be set, namely real-time load
state, peak hold state and automatic peak state. When there is no \"PEAK \" on the display, it is the real-time
value state of the load, and the test value changes with the change of the load; press \"Peak \" key, when the
word \"PEAK \" is displayed, it is the peak hold state The displayed test value is the MAX value of the test
