square- wave annunciator ( ) on the front panel is flashing. (Press
again if it is not.)
2 Press or to step through the available duty cycle values.
The pulse width can be stepped through 256 steps, where each step is
1/(256 × frequency) more than the previous step. The display will
automatically adjust to a 5 digit resolution (ranging from 9.9999 ms to
9999.9 ms)
3 Press again or Shift > Save to save the changes.
When all the appropriate parameters have been set, press to generate
