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 with a lighting rod connected with a

copper cable to a 1.5 m long copper-grounding rod.

4.5.2 Installation

Drive the copper rod into the ground at a distance of about 1 meter from the tripod. Use the 12 AWG copper isolated

wire to connect the grounding rod with the copper clamp. Make sure the contacts are clean and not corroded. Attach

the other end of the grounding cable to the specified screw at the bottom of the protective enclosure.

4.5.3 Maintenance

During every visit to the Met Station, check if the grounding cable is properly connected to the grounding rod. Clean

contacts if necessary.
