GPS Signal
When a measurement is started (either on the instrument, remotely triggered, or on a timer) the GPS location is
recorded.
The satellite icon at the top of the instrument display shows the current status of the GPS signal strength.
No GPS signal available
Poor GPS signal
Good GPS signal
The current UTC time and date are also read from the GPS signal and the instrument’s clock is also adjusted at
the start of each measurement using the information from the GPS signal.
The GPS clock will adjust the seconds and minutes on the optimus clock to within half an hour to match UTC.
This corrects for any drift automatically. The date and time must be set by the user to the correct local date and
time before the measurement session.
