Data Logging - Javad TRIUMPH-3NR User Manual

The offsets are different because of the difference in location between the slant measuring point
and the vertical measuring point.
Measure the antenna height to the control point or marker edge, either the slant height or the
vertical height.

6.2. Data Logging

See the remaining sections in this chapter for more information on data logging.
Turn on the receiver.
•
Once the receiver has locked onto eight or more satellites the SAT light will green.
•
The red color of POS LED indicates that the receiver has not solved a position. Four or
•
more satellites provide optimal positioning.
Once the red POS LED is green, the receiver has a position and surveying can begin;
•
wait for green light before beginning data collection. This ensures that the receiver has
the correct date and time and is locked on to 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.
To begin collecting data, press and hold the Record (FN) button (for more than one
•
second and less than five seconds).
Release the Record button when the REC (recording) LED 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.
When finished, press and hold the Record button until the REC LED light goes out.
To turn off the receiver, press and hold the power button until all lights go out, then release.
