6.7.3 ADC Command Reference
This section describes the ADC command reference of this instrument.
“Initial value” shows the status when the *RST command is executed.
CAUTION: Ensure the following when using the USB interface.
The device setting conditions are output by reading the data after executing the query command.
When executing the query command, set a wait time of 20 ms after the last command.
