enable the touch screen to select it. The available sizes include "Small",
"Medium", and "Large". Also, you can rotate Wave Vertical
adjust the waveform size.
Press More → AutoSetting to adjust the vertical scale and offset of the

operation results to the optimal value according to the current configuration, so
as to better observe.
Press More → Sensitivity to set the sensitivity of the digital signal converted

from the analog signal on the source. For setting methods, refer to descriptions
in "Parameter Setting Method".
Press More → Label to set the label for math operation results. For details,

"OR" Operation
Performs logic "OR" operation on the waveform voltage values of the specified
sources point by point and displays the results. In operation, when the voltage value
of the source channel is greater than the threshold of the corresponding channel, it is
regarded as logic "1"; otherwise it is logic "0". The results of logic OR operation of
two binary bits are as shown in Table 6-3.
