If you select [Specied 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 buer
memory if the maximum capacity of the internal buer 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
specied amount of time has elapsed and the start of the next recording operation. Recording is not
performed during this time.
Downtime

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.

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.

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.

Data volume – – More data Less data
Weak Strong – –
Waveform peaks Easier to capture* More dicult to
capture
*: If the data refresh interval and recording interval are short.
Easier to capture* More dicult to
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 eective noise rejection. For more
information about cuto frequencies, see the section about each module’s digital lter in “10.2
Plug-in Module Specications” (p. 243).
• To maximize the eectiveness of the digital lter, congure the [Power frequency lter] setting
according to the power supply frequency in the region where the instrument is being used.
See “7.1 Conguring 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.

What you want to do Data refresh interval Recording interval
Record a signal that’s changing quickly
(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 eects 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, reecting 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 identier, see “Module identiers” (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 aect 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.

When measuring instrumentation devices
• When measuring a 4-20 mA current, connect a 250 Ω resistor between the positive and negative
input terminals.
See “Connecting voltage cables and thermocouples” in the Quick Start Manual.
• The [1-5 V] range is convenient when measuring output from 4-20 mA instrumentation devices.
• The [1-5 V] range is a range in which the lower and upper limits of the [10 V] range’s display
range are automatically set to 1 V and 5 V, respectively. If you wish to change the upper and
lower limit values, use the [10 V] range.
• The Strain Unit does not support 4-20 mA current measurement.
You can use the scaling function to convert measured voltage values to the desired values.
See “1.5 Using the Scaling Function” (p. 42).

f.s. range), 1638.3°C (500°C f.s. range), or 3276.6°C (2000°C f.s. range).
There are limits on the data refresh interval that can be set.
See “Thermocouple wire break detection” (p. 23).
Performs reference junction compensation inside the measurement module.
Use this setting when the thermocouple (or compensation lead wire) is connected
directly to the instrument.
The measurement accuracy is determined by adding the temperature measurement
accuracy to the reference junction compensation accuracy.
Use this setting when connecting an external zero junction compensation device (0°C
ice water, etc.).
The measurement accuracy is dened by the temperature measurement accuracy
alone.
Measurable temperature range
The measurable temperature range depends on the type of thermocouple being used.

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 aected 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 eective
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 Specications” (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.
