For GPS, coordinates, status (Fixed, Float, Autonomous) and HRMS and VRMS accuracy estimates are displayed at all

times. The icons at the left are for zooming and panning. From top to bottom, they are: zoom extents, zoom in, zoom

out, zoom window, zoom previous and point display control. If you prefer to work in a pure text screen, without

graphics, you can tap the helmet icon and select

TEXT.

The following dialog will appear.

The Text screen uses a large character size for easy viewing, and limits options to Monitor/Skyplot, Offset and Store.

You can return to the graph view by tapping the

GRAPH

button. You can also temporarily view your points on the

screen by tapping

, then tap

Back

to return to the text-based data collection screen. Note that the program will

remember which screen you were in last (Graph or Text) and return to that mode of data collection automatically.

In addition to pressing

Enter

, Points can be Stored by selecting this icon (ALT-S).

readings when taking measurements. You will be prompted for how many readings to take (up to 999). Taking 100

readings is also a way to gauge how fast your GPS equipment takes measurements. If 100 readings are taken in 10

seconds, you are reading at 10 per second, or 10 hertz (hz). After the readings are taken, a display appears showing the

range and standard deviation of the readings.
