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.

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.
