Trend interval [/div]
Specify the trend/storage interval (sampling interval and recording interval) in terms of
time per division on the time axis. You cannot choose a sampling interval that is faster
than the scan interval. See the table under “Save Interval” below.
High-speed model: 5s, 10s, 15s, 30s, 1min, 2min, 5min, 10min, 15min, 20min, 30min,
1h, 2h, 4h, 10h
Medium-speed model**: 15s*, 30s, 1min, 2min, 5min, 10min, 15min, 20min, 30min, 1h,
2h, 4h, 10h
* Only during fast sampling mode.
** You cannot use fast sampling mode on models with the external input channel (/MC1) option.
Save Interval (when recording display data)
Select the size of a record data file. The recorded data is divided by the file size
specified here. The available settings vary depending on the Trend interval setting.
Trend interval 5 s 10 s 15 s 30 s 1 min
Sampling interval 125 ms 250 ms 500 ms 1 s 2 s
Selectable range of
auto save interval 10 min to 12 h 10 min to 1 day 10 min to 3 days 10 min to 7 days 10 min to 14 days
Trend interval 2 min 5 min 10 min 15 min 20 min
Sampling interval 4 s 10 s 20 s 30 s 40 s
Selectable range of
auto save interval 10 min to 14 days 10 min to 31 days 10 min to 31 days 10 min to 31 days 1 h to 31 days
Trend interval 30 min 1 h 2 h 4 h 10 h
Sampling interval 1 h 2 h 4 h 8 h 20 h
Selectable range of
auto save interval 1 h to 31 days 1 h to 31 days 2 h to 31 days 4 h to 31 days 8 h to 31 days
Display Update 2nd Interval
Enabled when [Trend Rate Switching] is turned [ON] under [Environment] - [Detail
Setting] in the [Basic Setting] tab. Select a rate from the list.
The selectable 2nd intervals are the same as those for Trend interval.
Direction
Set the display direction of the trends to [Horizontal], [Vertical], [Wide], or [Split].
Trend Clear
ON Clears the displayed waveform when the memory sampling is started.
OFF Does not clear the waveform when the memory sampling is started.
Message direction
Set the display direction of messages to [Horizontal] or [Vertical]. When the trend is set
to Vertical, the message direction is fixed to [Horizontal].
Scale Digit
Select the [Normal] or [Fine].
Fine If the scale value is two-digit display, it can be changed to three digits. For
example, if the scale range is “49.0 to 51.0,” the scale values are displayed using 3
digits as shown below.
Value Indicator
The current value is displayed as a mark or a bar graph.
Trend Line
Set the line width of the trend in dots (1 to 3).
Grid
Select the number of grids to be displayed in the waveform display area of the trend
display.
Settings Description
4 to 12 Displays a grid that divides the display width into 4 to 12 sections.
Auto Displays the same number of grids as the number of scale divisions of the
first assigned channel of the group.
