Setting the Trend Display Conditions
• Selecting the Waveform Parameter to Be Displayed (Graph 1 and Graph 2)
You can display two trend graphs. For each graph, you can specify the trend target
waveform and the waveform parameter. When the waveform parameter is Marker,
you can set the Marker Position.
Selecting the Target Waveform (Trace)
From the Trace box, select the target waveform for the trend display
Chan1 to Chan8 (channels 1 to 8), Math1 to Math8 (computed waveforms)
* Chan1 to Chan4 (channels 1 to 4), Math1, and Math2 on the DL7440.
Selecting the Waveform Parameter
From the Parameter box, select the target waveform parameter of the trend display
(same expression as the communication command). For the meanings of the waveform
parameters and the marker cursor, see the explanation in section 10.5 or 10.6.

Setting the Marker Position
Set the marker position if Marker(M1) or Marker(M2) is selected as the waveform
parameter.
• Setting the Conditions for Retrieving the Measured Values of Waveform
Parameters (Common)
Number of Displayed Measured Values (Data Number)
Select the number of measured values (measured values retrieved from the DL7400
into the PC) to be displayed in the cells of Excel from the following: 10, 20, 50, 100,
200, and 500. If the number of measured values exceeds the selected number, the
values are cleared from the oldest values to display the newest measured values.
Retrieve Interval
Select the retrieve interval from the following: 2 s, 5 s, 10 s, 30 s, and 60 s. However,
of the selected waveform parameters, select the interval to match the longest
parameter cycle measured on the DL7400.
Measurement Range
You can set the range on the time axis for measuring the waveform parameter.
Range1 and Range2 are the start and end points, respectively. The selectable range
is ±5 divisions, and the resolution varies depending on the specified record length.
However, the measurement start point cannot be set to the same point as the
measurement end point or to a value to the right of the measurement end point.
