Programmable Pulse: Slow Code
Use the “SLOW CODE UTC?”, or “SLOW CODE LCL?” mode to cause the output voltage to be
held high and go low for six seconds on the day, four seconds on the hour and two seconds on the
minute. Be sure to check for Local or UTC format, otherwise the time could be off by as much as
the local offset plus Daylight Saving Time, if used.
For RS-232 commands, see Section 11.2.10
