NOTE
The internal Reference Oscillator receives power whenever the power cord is

connected to a power source, the frequency of the reference signal may drift
until the oscillator stabilizes. Specifications for the stability of the standard
internal timebase and the optional Oven Timebase are provided in Chapter 3.
