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 Marker Position.
Selecting the Target Waveform (Trace)
From the Trace list, select the target waveform for the trend display from the
following:
Chan1 to Chan4 (or Chan1 to Chan2 (channels 1 to 2) for the DL1620) (channels 1
to 4), Math1 to Math2 (or Math1 only for the DL1620) (computed waveforms)
Selecting the Waveform Parameter
From the Parameter list, select the target waveform parameter for the trend display
(same expression as the communication command) from the following. For the
meaning of the waveform parameters and the marker cursors, see the explanations
in sections 9.1 or 9.2.

Setting the Marker Position
You can set the marker position if Marker(M1) or Marker(M2) is selected as the
waveform parameter.
• Setting the Conditions for Retrieving the Measurement Values of Waveform
Parameters (Common)
Number of Displayed Measurement Values (Data Number)
Select the number of measurement values (measurement values retrieved from the
DL1620/DL1640/DL1640L to the computer) to be displayed in Excel from the
following. If the number of measurement values exceeds the selected number, the
values are cleared from the oldest values to display the newest measurement
values.
10, 20, 50, 100, 200, and 500
Retrieve Interval
Select the retrieve interval from the following. However, of the selected waveform
parameters, select the interval to match the longest parameter cycle measured on
the DL1620/DL1640/DL1640L.
2 s, 5 s, 10 s, 30 s, and 60 s
