Clock Setup in Free-Running Mode

In free running mode the internal oscillator in the 933A is not disciplined
by an external clock signal, such as IRIG-B or GPS. When manually
setting the internal clock on the 933A always set it to your Local time.
Verify this in the second line of Figure 3.4, which states, Instrument
Time:LOCAL. If it says, Instrument Time:UTC, you will need to
press the far left soft key, SELECT LOCAL, to switch it to local time.
TIP: In free running mode, use an accurate external time source as a
reference and set the 933A time ahead enough so that you can "set it"
when the reference time arrives at the top of minute. The Model 933A
clock time is "set" when you press the SAVE CHANGES soft key.
