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.
Conversion Range and Step
You can specify the range using data numbers or by using cursors. For the method of specifying
the range using cursors, see the procedure in section 3.4, “Statistical Computation over an
Area of Measured/Computed Data.” 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 Converting Data
• There is a limit in the number of data that Excel and Lotus1-2-3 can handle. Before
conversion, set the data to be converted, range of data, and steps such that the
appropriate number of data are targeted. Also, if there is little free memory in the PC,
Excel or Lotus 1-2-3 may not be able to load the data.
• If you specify conversion conditions that exceed the limits of Excel or Lotus 1-2-3,
data is automatically divided prior to conversion, therefore multiple files are created.
The file names are assigned automatically with sequential numbering. (For example if
a file, data.MXD is converted to Excel and divided into n files, the resultant file names
are data.MXD.0000.xls, data.MXD.0001.xls, … data.MXD.000n.xls.)
• When converting to Excel, up to 252 channels and 65510 data are saved in a single
conversion file (when channels are in columns and data are in rows).
• When converting to Lotus, up to 252 channels and 8166 data are saved in a single
conversion file (when channels are in columns and data are in rows).
• 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”
