Supplementary Explanation
• When buffering mode is selected, the shortest sampling period is set to "144µs" (see
page 5-9). If the sampling period is set to "100µs" when the mode is selected, change
the sampling period to a longer period, or an error code (70) is returned.
5. Confirmation of control signal
When the control signal of PC CS (CTS), DR (DSR) is checked, it is possible to know
whether data is under accumulation (including waiting for trigger) or data accumulation is
completed without affecting measurement. This function helps prevent data continuity from
being interrupted if the communication is executed during data accumulation. It is also
possible to confirm whether the set number of accumulation data points has been
accumulated. To use this function, set the control signal must have been set to "Valid" in
step 3.

6. Transmission of stop command
The stop command has the 2 functions below.
• Input during accumulation to stop accumulation.
• Terminating the accumulation operation.
For updated continuous mode or updated trigger mode, accumulation and the
accumulation operation are stopped when the stop command is input.
Since it is necessary to start data reading after completion of the accumulation operation,
stop the accumulation operation before reading data.
