4.4.3 Use
Operation of the charging unit/regulator is almost completely automatic. User intervention is limited to toggling the
power to the datalogger On/Off.
A red light (LED) indicates when a charging source is connected to the charging unit/regulator.
4.4.4 Maintenance
Apart from checking periodically if all contacts are firmly connected and not corroded, no maintenance is neces-
sary.
4.5 Grounding
4.5.1 General
To protect the Met Station against lightning strikes, as well as to ensure proper functioning of the system, all com-
ponents (datalogger, sensors, power supply, housing, mounts, etc.) need to be referenced to a single common earth
ground. In the event of a lightning strike, the purpose of the earth ground is to minimize damage to the system by
providing a path of low resistance to a point of low potential. This is achieved by connecting a copper cable from the
datalogger to the metallic part of the buoy hull part of which is submerged in water.
