4. “dr1” is input by the communication software and “Enter” key
is pressed.
The following numerical value returns from the set.

**: Hexadecimal (“00” to “FF”)
5. To change the adjusted value, “dw1 ##” is input by the com-
munication software and “Enter” key is pressed.
The following numerical value returns from the set.
“Write Channel1:0x##”

When waveform level is smaller than 5.8 V, the numerical
value of “##” is increase.

6. “ds” is input by the communication software and “Enter” key
is pressed and the numerical value is saved.
7. The “Reset” button is pressed and turn the power off.
Example:
When the returning numerical value “8a” and the waveform level
is 5.6 V.
The numerical value is increased, and adjusted for a waveform lev-
el to become 5.8 ± 0.1 V with “8b→8c→8d→8e→8f→90→91...”.
