Description
1
Ideal
This is the highest possible confidence level to be
used for applications demanding the highest possible
precision at all times.
1-2
Excellent
At this confidence level, positional measurements are
considered accurate enough to meet all but the most
sensitive applications.
2-5
Good
Represents a level that marks the minimum
appropriate for making business decisions. Positional
measurements could be used to make reliable in-
route navigation suggestions to the user.
5-10
Moderate
Positional measurements could be used for
calculations, but the fix quality could still be improved.
A more open view of the sky is recommended.
10-20
Fair
Represents a low confidence level. Positional
measurements should be discarded or used only to
indicate a very rough estimate of the current location.
>20
Poor
At this level, measurements are inaccurate by as
much as 300 meters with a 6 meter accurate device
(50 DOP × 6 meters) and should be discarded.

GPS coordinates
and device orientation can be viewed.
Coordinates will be stored for each
measurement. A “No signal” indicator means
that the GNSS GPS module is not able to
receive a positioning signal and no GPS
coordinates will be stored.
After switching the Zehntner ZRM 6010 on, it takes up to 15 minutes until the unit is
receiving coordinates. The performance of the GPS module can be affected by
narrow streets with high buildings that prevent clear view to the sky. Indoors it is
normally not possible to receive coordinates.
