3.6 Safety measures
The safety class 1 instrument, the MRS 120-3, may only be
plugged into a socket which has been installed in accordance with
regulations and is fitted with a protective earth terminal. The safety
effect may not be undone by using an extension lead without an
earth wire. If the voltage is coming from mains supplies without a
protective earth terminal, arrange for an electrician to create a
comparable level of protection in accordance with valid installation
regulations.
3.7 Levelling
In order to function properly, the MRS 120-3 moisture analyzer
must be precisely horizontal.
The instrument is fitted with a “levelling bubble” and two rotatable
feet for level-control, with the aid of which it is possible to
compensate for small height differences and/or unevennesses in
the surface on which the instrument is standing.
The two screw feet must be adjusted so that the air bubble is
precisely in the center of the sight glass of the levelling bubble.
NOTE
The instrument must be carefully relevelled each time it is moved in
order to obtain accurate measurements.
