Guidelines for Correct Results with GNSS Surveys
Successful GNSS measurements require undisturbed satellite signal reception.
For kinematic use, be sure to select measurement positions with best satellite
reception possible. Use the instrument in location which is free of obstruc-
tions such as trees, buildings or mountains for best measurement results.
Centre the instrument precisely over the target positions.
Batteries
Operating Principles
The battery must be charged before using it for the first time because it is
•
delivered with an energy content as low as possible.
The permissible temperature range for charging is from 0 °C to
•
+40 °C/+32 °F to +104 °F. For optimal charging, we recommend charging
the batteries at a low ambient temperature of +10 °C to +20 °C/+50 °F to
+68 °F if possible.
It is normal for the battery to become warm during charging. Using the
•
chargers recommended by Leica Geosystems, it is not possible to charge
the battery once the temperature is too high.
For new batteries or batteries that have been stored for a long time
•
(> three months), it is effectual to make only one charge/discharge cycle.
For Li-Ion batteries, a single discharging and charging cycle is sufficient.
•
We recommend carrying out the process when the battery capacity indic-
ated on the charger or on a Leica Geosystems product deviates signific-
antly from the actual battery capacity available.
The batteries can be operated from −20 °C to +55 °C/−4 °F to +131 °F.
•
Low operating temperatures reduce the capacity that can be drawn; high
•
operating temperatures reduce the service life of the battery.
