Voltage Measurement
Attention!
!
Regardless of the value of the measured voltage, as a
safety precaution, do not exceed the sum of 500 V
CAT II for measured voltage plus voltage against earth
when directly connecting up the multimeter!
The left-hand connection socket marked „
⊥
“ should be con-
nected whenever possible and for all voltage measurements to
the point with the lowest potential against earth.
