1.2 Setting Measurement Conditions
This section describes how to congure settings such as the recording interval and recording time.
Settings cannot be changed while measurement is in progress. Stop measurement and then
change the settings.
You can select the recording method.
Continuous recording
Sets the recording time setting to [Continuous].
Recording will continue until you press the STOP key. Recording can
be stopped with a trigger.
See “Stop triggers” (p. 84).
Time-specied recording
Sets the recording time setting to [Specied time].
The setting indicates the amount of time for which to record (the
recording length). Recording will stop once the set time has elapsed.
Recording can be stopped before the set time elapses with the STOP
key or a trigger.
Repeat recording
Sets the repeat recording setting to [ON].
Recording will resume after stopping (due to stop trigger conditions or
the completion of recording for the set recording time). Recording will
repeat until you press the STOP key. If the repeat recording setting is
[OFF], recording will stop after one iteration.

The setting cannot be changed from [Normal]. Hioki plans to add new functionality in the future.

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).

Days, hours, minutes, seconds
Continuous Recording will continue until you press the STOP key.
Measurement can also be stopped with a trigger.
See “Stop triggers” (p. 84).
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).
6
Under [Alarm source], choose whether to record the alarm source channel during alarms.
Set to [ON] when you’re using an alarm and you wish to save data for the alarm source channel.
Set as necessary as the amount of data will increase.
OFF , ON
When the recording time is set to [Specied time] and repeat recording is set to
[ON]
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.
Recording
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 Interval at which measurement modules refresh measurement data
Recording interval 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

Under [Update], select the data refresh 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 U8550, U8551,
LR8530, LR8531 U8552, LR8532 U8553, U8554, LR8533, LR8534
OFF From 10 ms*1From 20 ms*2
From 1 ms*4
ON From 20 ms*1From 50 ms*3
*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.

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.
Data refresh interval Recording interval
Short Long Short Long
Strength of the power

Data volume – – More data Less data
Waveform peaks Easier to capture* More di󰀩cult to
capture
Easier to capture* More di󰀩cult to
capture
*: If the data refresh interval and recording interval are short.
•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.

What you want to do Data refresh interval Recording interval
Record a signal that’s changing quickly
(electrical signal, etc.)
Shorter Shorter
Record a signal that’s changing slowly
(temperature, etc.)
Longer Longer
Record fast and slow signals at the same time Shorter for modules used to
measure fast signals
Longer for modules used to
measure slow signals
Shorter
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.
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.

1.3 Conguring Input Channels
Congure input channels for voltage measurement, temperature measurement, etc.
Channel
Un-m
The letters nand mrepresent a module number and a channel
number, respectively.
Input Selects the type of measurement target.
Voltage, thermocouple, humidity, etc.
Range Sets the magnitude of the input signal.
Set the waveform color, scaling, and comments as necessary.
These settings can be congured either on each channel’s individual settings screen or on the
settings list screen for multiple channels.
