Continuous

If you select [Specied 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 bu󰀨er

memory if the maximum capacity of the internal bu󰀨er memory is exceeded. It is recommended to use auto

saving since deleted data cannot be restored.

See “Auto save (real-time save)” (p. 106).

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



Recording will continue until you press the STOP key. Measurement can also be stopped with a trigger.

See “Stop triggers” (p. 84).

Internal processing will take some time (downtime) between the time that recording stops after the

specied amount of time has elapsed and the start of the next recording operation. Recording is not

performed during this time.

Downtime

You can record without any downtime by setting the recording time to [Continuous] and enabling

auto saving and le segmentation. Saved data les can be segmented using the desired time

segment.

Measurement module data refresh intervals

This section describes how to set the data refresh interval for each measurement module separately from the instrument’s recording interval.

Data refresh interval

Recording interval

Interval at which measurement modules refresh measurement data

Interval at which the instrument captures data from measurement modules

A list of connected modules will be displayed.

• [Unit 1] to [Unit 4]: Plug-in modules

• [Remote 1] to [Remote 7]: Wireless modules

Settings and Operation

, 1 ms, 2 ms, 5 ms, 10 ms, 20 ms, 50 ms, 100 ms, 200 ms, 500 ms, 1 s, 2 s, 5 s, 10 s

Ordinarily, this setting should be set to [Auto]. When you choose [Auto], the shortest data refresh interval will be set for each module based on the recording interval. The available data refresh interval settings vary with the modules in use and the wire break detection setting.

Wire break detection

OFF From 10 ms*

ON From 20 ms*

*1: Settings start at 100 ms when using a Pt1000 with the U8551 or LR8531. *2: When using 15 or fewer channels, the 10 ms setting is available. *3: When using 15 or fewer channels, the 20 ms setting is available. *4: No wire break detection function is available.

• When the data refresh interval is set to a value other than [Auto], it is recommended to use

longer times.

This will allow you to reduce the digital lter’s cuto󰀨 frequency to eliminate low-frequency noise.

• You can eliminate power supply frequency noise by setting the data refresh interval so that the

[Filter] setting is 50 Hz or 60 Hz.

Setting Measurement Conditions

Under [Filter], check the lter’s cuto󰀨 frequency.

The lter’s cuto󰀨 frequency will change depending on the data refresh interval setting. Check the cuto󰀨 frequency that is displayed for each module.

Relationship between the data refresh interval and the recording interval

• Measurement modules send data to the instrument once each data refresh interval.

• The instrument receives data from measurement modules once each recording interval.

• Even if a measurement module’s data refresh interval is short, it will not be possible to record waveform peaks if the instrument’s recording interval is long.

capture

• For the U8550 to U8553 and LR8530 to LR8533 modules, the longer the data refresh interval,

the lower the digital lter cuto󰀨 frequency, yielding more e󰀨ective noise rejection. For more information about cuto󰀨 frequencies, see the section about each module’s digital lter in “10.2 Plug-in Module Specications” (p. 243).

• To maximize the e󰀨ectiveness of the digital lter, congure the [Power frequency lter] setting according to the power supply frequency in the region where the instrument is being used. See “7.1 Conguring Settings” (p. 164).

• For modules whose data refresh interval is longer than the recording interval, the rst two data points will be continuous, and there will be a delay.

(electrical signal, etc.)

Record a signal that’s changing slowly (temperature, etc.)

Record fast and slow signals at the same time Shorter for modules used to

Since you can set the data refresh interval separately for each module, the instrument can be used as follows:

• For module 1, set the data refresh interval to 2 s so that you can eliminate power supply noise

and reduce the e󰀨ects of noise when performing temperature measurement using thermocouples.

• For module 2, set the data refresh interval to 10 ms so that you can record battery voltage

uctuations.

• For module 3, set the data refresh interval to 1 ms so that you can record changes in control signals at the maximum speed.

• Set the instrument’s recording interval to 1 ms, reecting the shortest data refresh interval. The instrument will record data from modules 1 through 3 every 1 ms.

Settings and Operation

If the instrument’s recording interval is shorter than a module’s data refresh interval, the same value will be recorded for that module’s data. Example: If the recording interval is 1 ms and the data refresh interval is 1 s, 1000 pieces of data all

of which have the same value will be recorded.

For more information about the module identier, see “Module identiers” (p. 49); about the lter of U8554 and LR8534 Strain Unit, “Measuring strain” (p. 27).

Data refresh interval of pulses

Pulse data will be refreshed at the data refresh intervals. The data refresh interval of pulses will automatically be set depending on input types.

Input type Data refresh interval

Integration 1 ms

Rotational speed r/s or r/min (Smoothing: 1 s) 10 ms

r/min (Smoothing: 2 s to 60 s) 50 ms

• The data refresh interval setting does not a󰀨ect pulse counting processes.

• Even if the data refresh interval of pulses is equal to that for the measurement module, these data will not simultaneously be refreshed when the recording interval is shorter than the data refresh interval.

Thermocouple wire break detection

• The system checks for wire breaks by applying a minuscule current each date refresh interval when measuring temperature using thermocouples.

• Measured values are not a󰀨ected since wire breaks are detected when measurement is not being performed.

• If the data refresh intervals are the same, setting [Burn out] to [ON] will result in less e󰀨ective

noise rejection since it results in a cuto󰀨 frequency that is higher than the [OFF] setting. Check “Digital lter” of each module in “10.2 Plug-in Module Specications” (p. 243) for the cuto󰀨 frequency.

• If the thermocouple resistance exceeds roughly the next value, the system will determine that a wire break has occurred.

When using wire break detection in thermocouple measurement, values are treated as follows:

• When there is a wire break or the thermocouple’s measurable range is exceeded in the positive direction, the value is treated as a wire break (BURNOUT).

• When the thermocouple’s measurable range is exceeded in the negative direction, the value is treated as (-OVER).

1.4 Conguring the Waveform Display

This section describes how to set how waveforms are displayed (display color, display position, zoom factor, etc.).

Conguring the display of the vertical axis

This section describes how to congure the display in the vertical axis direction.

You can set the waveform display position and zoom factor for each channel on the individual settings screen. You can use [Display] on the settings list screen to congure the settings. (See p. 50.) There are two methods for setting the display position:

• Setting the zoom factor and zero position

• Setting upper and lower limit values

Setting the zoom factor and zero position

Set the waveform display position by specifying the zoom factor and zero position (position of 0 V that serves as the reference). The zoom factor will be increased and decreased based on the zero position.

Vertical display range and 0 V display position

Zero position: 50% Zoom factor: 1×

Zero position: 25% Zoom factor: 2×

measurement based on specic conditions and signals. When a specic condition (a trigger condition) occurs, the trigger is said to activate. The points at which triggers activate (i.e., the points in time at which trigger conditions are satised) are known as trigger

points, which are identied by the

When a trigger activates, you can start or stop recording.

Specic

condition

Start trigger Starts recording when the trigger condition is satised.

Example: Start recording when the temperature reaches or exceeds 50°C.

Stop trigger Stops recording when the trigger condition is satised.

Example: Stop recording if a signal falls below 1 V.

External trigger Allows you to activate a trigger using an external signal. (I/O 3)

Example: Control recording based on the operation of other devices.

Pre-trigger Records data before the trigger point.

Example: Record a phenomenon that precedes an anomaly.

Interval trigger Applies the trigger at a set interval.

Example: Record data at one-hour intervals.

IMPORTANT

• If the trigger function is [OFF], you can start recording by pressing the START key. (Free-run)

• If the trigger function is [ON], the instrument will remain in the “trigger standby” state until the

trigger condition is satised. Recording will start when the trigger condition is satised.

• The “trigger standby” interval will be shown on the monitor screen. See “1.9 Checking Input Signals (Monitor Function)” (p. 58).

• The next trigger will not be accepted while trigger processing remains in progress. Trigger output will be active while trigger processing is in progress. For more information about trigger output, see “Trigger output” (p. 180).
