6.3.2 Emptying the <strong>T8</strong><br />
Also read chapter 5.1.<br />
1. Remove the connecting rubber tube from the refilling tube. In a<br />
downwardly installation the refilling tube is the marked tube, in<br />
an “upwardly” installation the refilling tube is the not marked<br />
tube.<br />
2. Connect the empty syringe to the refilling tube and completely<br />
suck out the Tensiometer water.<br />
3. Connect rubber tubes and filing tube.<br />
6.4 Lightning protection and grounding<br />
In-the-field measuring equipment is always susceptible to electrical<br />
surge. <strong>UMS</strong> sensors and stations are protected against over voltage<br />
and false polarity as far as this is technically achievable.<br />
But there never can be total lightning protection. Lighting strikes are<br />
unpredictable and vary significantly with region, voltage and<br />
destructiveness. A proper lightning protection has to be considered<br />
whenever a system with several sensors and loggers is installed.<br />
Passive lightning protection measures would comprise one or more<br />
grounding rods, preferably with ground water contact, but without (!)<br />
an electrical connection to the measuring system.<br />
With an active lightning protection each sensor and the logger are<br />
equipped with an individual grounded surge protection module.<br />
