Also read chapter 5.1.
1. Remove the connecting rubber tube from the refilling tube. In a
downwardly installation the refilling tube is the marked tube, in
an "upwardly" installation the refilling tube is the not marked
tube.
2. Connect the empty syringe to the refilling tube and completely
suck out the Tensiometer water.
3. Connect rubber tubes and filing tube.

6.4 Lightning protection and grounding

In-the-field measuring equipment is always susceptible to electrical
surge. UMS sensors and stations are protected against over voltage
and false polarity as far as this is technically achievable.
But there never can be total lightning protection. Lighting strikes are
unpredictable and vary significantly with region, voltage and
destructiveness. A proper lightning protection has to be considered
whenever a system with several sensors and loggers is installed.
Passive lightning protection measures would comprise one or more
grounding rods, preferably with ground water contact, but without (!)
an electrical connection to the measuring system.
With an active lightning protection each sensor and the logger are
equipped with an individual grounded surge protection module.
Please contact UMS or your UMS dealer for assistance about
integrating T8 into your measurement system.
