Prego Setup
In the case of a GPS/GLONASS antenna, the offset is entered depending on
the type of measurement taken. For vertical, the offset is simply added to the
measured vertical height to produce a “true” vertical height. For slant
height, the vertical height must be first calculated using the radius of the
antenna, then the offset can be added. The offsets are not the same number
because of the difference in location between the slant measuring point and
the vertical measuring point.
3. Record the antenna height, point name and start time in the field notes.
4. Connect the antenna to the receiver using the antenna cable.
Setup Receiver
This section assumes you have already configured your receiver using
PCView.
5. Press the MinPad
power
key and release it to turn the receiver on. The
STAT (status) light (LED) will blink red at first.
6. Once the receiver has locked onto satellites, the STAT light will blink
green for GPS satellites, orange for GLONASS satellites, and a short
red blink indicating it has not solved a position.
7. Once the short red blink is gone, the receiver has a position and
measuring can be started. You should wait until there is no red blink
before starting data collection. This ensures that the receiver has the
correct date, time and is locked onto enough satellites to ensure good
quality data.
The process of locking onto satellites normally takes less than one
minute. In a new area, under heavy tree canopy, or after resetting the
receiver, it may take several minutes.
Collect Data
8. To begin collecting data, press and hold the
FN
(function) key for more
than one second and less than five seconds.
9. Release the
FN
key when the REC (recording) LED light turns green.
This indicates that a file has opened and data collection has started. The
REC LED blinks each time data is saved to the internal memory.
Tip: You can use PCView to log data. See the
PCView User’s Manual
for this procedure.
