1 Enter a title comment in the [Title comment] field (optional).

“Title comments” in “1.8 Entering Comments” in the Instruction Manual.

2 Configure the [Start] and [Stop] settings.

You can start measurement at the specified time and date. Once measurement has started, recording will start based on the trigger settings.

You can stop measurement at the specified time and date. Recording will stop when measurement stops.

Between the times measurement starts and stops, recording will start and stop based on the trigger conditions.

• Measurement start: The instrument has started measurement and is waiting for a trigger.

• Recording start: A trigger has occurred, and the instrument has started recording.

Start	Manual ☑	Starts measurement based on the START key or external I/O.
	Time	Starts measurement at the specified time and date. YYYY-MM-DD HH:MM The instrument will transition to the waveform screen at START key input and wait until the specified time and date to start measurement. If the specified time and date have already passed when the START key is pressed, the instrument will start measurement immediately.
Stop	Manual ☑	Stops measurement based on the START key or external I/O.
	Time	Stops measurement at the specified time and date. YYYY-MM-DD HH:MM Pressing the STOP key during measurement will cause the instrument to stop measurement, even if a stop time has been set.

3 Under [Recording mode], select type of recording.

Normal ☑	Data is recorded in synchronization with the internal clock.

The setting cannot be changed from [Normal].

4 Under [Recording interval], select the data capture interval.

Example: Choosing [10 ms] will cause data to be captured at a 10 ms interval (100 times per second).

1. *1

   ‌Setting available only when using a module with data refresh intervals including 1 ms.

   (when there is at least one U8553, U8554, U8556, LR8533, LR8534, or LR8536 module for which measurement is enabled).

The number of channels that can be used will be restricted based on the recording interval and auto save settings as well as whether any CAN Units are connected.

“Auto save (real-time save)” in “3.3 Saving Data” in the Instruction Manual.

5 Under [Repetitive recording], choose whether to repeat recording operation.

OFF ☑	Stops recording after one iteration.
ON	Repeats recording operation. Measurement will stop when you press the STOP key.

6 ​Under [Recording time], set the amount (length) of time for which you wish to record data.

Specified time	Records for the set amount of time. (Max. 500 days) Days, hours, minutes, seconds
Continuous ☑	Recording will continue until you press the STOP key. Measurement can also be stopped with a trigger. Enabling the Trigger Function

If you select [Specified time], the maximum time and data count will be displayed. The maximum amount of time that you can record varies with the number of channels in use and the recording interval.

If you select [Continuous], measurement will continue while deleting past data from the internal buffer memory if the maximum capacity of the internal buffer memory is exceeded. It is recommended to use auto saving since deleted data cannot be recovered.

“Auto save (real-time save)” in “3.3 Saving Data” in the Instruction Manual.

7 Under [Alarm source], choose whether to record the alarm source channel during alarms.

When using an alarm, you can save information about alarm source channels (channels that caused alarms).

OFF ☑	Does not save information about alarm source channels.
ON	Saves information about alarm source channels. Contents to be saved will differ depending on the data type. “11.8 Text Format” in the Instruction Manual.

Configure the setting as necessary since saving the alarm source channel will cause the file size to increase.

Alarm source information cannot be saved for CAN channels.

8 Under [Synchronous operation], select the primary or secondary (as necessary).

Multiple instruments can be synchronized for measurement.

“8.3 Configuring Sync Input/Output (SYNC) Terminals” in the Instruction Manual.

One instrument can be assigned to serve as the primary instrument, and up to four instruments can be assigned to serve as secondary instruments.

The synchronization signal from the primary instrument is received by the secondary instrument, which then operates in synchronization with the primary instrument’s sampling clock.

OFF ☑	Do not perform synchronous operation.
Primary	Uses this instrument as the primary instrument (one instrument only).
Secondary	Uses this instrument as a secondary instrument.
