Fig.2.
Establish a ground connection between ground of the laboratory and the ground terminal
of the instrument.
Because the instrument is built according to safety class I of IEC 359, the mains cable
contains a ground conductor which also has to be connected to ground of the local mains.
It is strictly forbidden to open the ground connection between "labo-
ratory ground
" and "Instrument
ground of local mains"!
Danger of life!
