Explanation
Selecting the waveforms to be judged
Input signal waveforms which are displayed as trace Nos. 1 to 4 (for DL1520/DL1520L, 1/
2/Math) can be judged. Computed waveforms can also be judged. Acquisition-memory data
is not available.
Setting the determination range: T-Range
The range of determination is set by the two cursors T1 and T2. The setting lies within
–5.00 div at the left side to +5.00 div at the right side measured from the center of the
display.
Note that this range is different from the one used for automated measurements.
Selecting waveform parameters and setting the range: Item, Upper, Lower
Up to four waveform parameters can be selected from the following items. If you do not
know the upper-limit or lower-limit, set the +side of the setting range, or (when the
keyboard shows this settings) select “
NAN
” (Ignore). In the latter case, the display will
show “
XXX
” at the corresponding setting.
For the meaning of each item, refer to page 8-10.
Each parameter can be set within the range given in the table below.

File name in case of FD(P-P) or FD(ACQ) action
When the waveform data are being saved to the floppy disk, a file number (starting from
“0001”) is automatically assigned. It is possible to insert a common file name (character
string consisting of up to four characters) before the assigned file number (for instance
“NOGO0001”).
The entered file name will be reset when the action becomes “NONE” or when GO/NOGO
determination is set to “OFF”.
The file name will not be reset if the GO/NOGO determination is executed/aborted using
EXEC and ABORT soft keys.
Example of data format
In case of NO-GO determination, the measurement values will appear. For the other
contents, refer to page 9-6.
