When this event occurs, the oscilloscope will trigger on the clock line (SCL)
transition edge of the last bit of data. After this trigger condition is selected:
- Press Bit X, and set the current bit with the following two methods.
Method 1: First rotate the multifunction knob to switch to the data bit
that needs to be operated on. Then press down the knob continuously to
set the current bit. As shown in the figure below, the left is its binary
format, and the right is its corresponding Hex format.
Method 2: Press Bit X or enable the touch screen to select the data bit.
Then set it with the pop-up virtual keypad. For setting methods, refer to
descriptions in "
