Winding and Setting the Chronometer
o
The chronometer is provided fully wound but “stopped” by an internal friction element
which prevents the balance from rotating. The starting procedure is detailed on the
instruction panel in the lid of the TTC.
(See Figure 13)
o
It is important to follow the Starting Instructions precisely, or damage can result to the
chronometer. NEVER TURN THE HANDS COUNTER-CLOCKWISE!
o
The chronometer can be set using the GPS display on the TTC once it has acquired
satellite signals (satellite lock is indicated by the latitude and longitude being shown on
the GPS display). Once “seconds” of the GPS display is one second ahead of the second
hand on the chronometer, the chronometer can be started by quickly rotating the entire
TTC clockwise and back and forth. The minutes and hours can be set once the
chronometer is running. NEVER TURN THE HANDS COUNTER-CLOCKWISE!
Normal Operations
•
Daily Operation
o
Reading Times from the Display Panel
1.
The GPS display (4 lines of 20 characters) shows Month:Day:Year,
Hours:Minutes:Seconds (UTC Time), Latitude, and Longitude.
2.
The Real-time Silicon Clock display (2 lines of 20 characters) shows
Month:Day:Year and Hours:Minutes:Seconds. This display is completely
independent from the other timekeeping systems and serves as a backup and
confirmation of proper operation. The time displayed on the Real Time Clock
display may be several seconds different from the UTC time shown on the GPS
display.
•
There is a provision to re-set the Real Time Clock from the GPS system,
if desired, by pushing the red “Set RTC” button, but this should be done
only if there is a reliable GPS time signal (latitude and longitude are
being displayed).
•
Pressing the “Set RTC” button when there is not a reliable GPS time may
result in inaccurate setting of the Real Time Clock.
o
Reading Time and Winding Reserve from the Chronometer
1.
The Hamilton chronometer has traditional hour, minute, and seconds hands.
The time may be set to UTC (recommended) or to any other time zone.
2.
Setting the chronometer is a manual operation and should not be required
unless power is lost for more than a day and the chronometer is allowed to run
down. During extended power outages, it is necessary for the operator to
manually wound the chronometer (see instructions below).
3.
The state of winding is indicated by the “UP – DOWN” dial immediately below
the “12” on the dial. Normally, while the autowinder is operating, the indicator
should be approximately at the 8-hour position. If allowed to wind down, the
hand will move clockwise, indicating how long it has been since the
