Converted Data
Specify the range using group numbers or channel numbers. You can select the channel
number by clicking in the dialog box as shown below.
If multiple record intervals exist in the data to be converted, select the recording interval.
Only the data of the channels having the selected recording interval is converted.
Converson Range and Step
You can specify the range using data numbers or by using cursors. For information on
specifying the range by using cursors, see “Procedure” in section 3.4. By specifying the
step, you can save data sampled at certain intervals rather than converting all the data in
the range (when step is set to 1).

Notes When Convertng Data
• There is a limit in the number of data points that Excel and Lotus 1-2-3 can handle.
Before conversion, set the data to be converted, the conversion range, and steps such
that the number of data points is appropriate. In addition, if there is little free memory
in the PC, Excel or Lotus 1-2-3 may not be able to load the data.
• If conversion conditions are specified that exceed the limitations of Excel or Lotus
1-2-3, the data is automatically divided before conversion. Therefore, multiple files are
created. The file names are assigned automatically with sequential numbering. (For
example, when converting the file “data.mxs” to Excel format, if the data is divided
into n number of files, they are named data.mxs.0000.xls, data.mxs.0001.xls, ..., data.
mxs.000n.xls).
• Up to 65510 data and 252 channels are saved to a single conversion file (when
columns are channels and rows are data).
• If you set the save destination to a storage medium that has slow access such as a
floppy disk, the saving of the data may take an extended time. It is recommended that
such storage medium not be selected for the save destination.
• Select a save destination with adequate free space.
• The measured data during a burnout or measured data that exceeds the upper/lower
limit of the measurement range are indicated as “OVER”or “OVER”
• If invalid data exists in the converted data (measured value of a channel without input
or computed value when the data used in the equation does not exist), the data is
indicated as “INVALID”
