Current measurement AC/DC
WARNING
Disconnect the test leads from the measuring instrument before
every measurement. Never perform measurements in circuits in
which a voltage over 250 V can occur. This also applies if the
conductor which is to be tested is insulated.
Never reach behind the hand protection during measurement -
danger to life!
Select the current range (A).
Use the SELECT button to select the
measurement type “AC (~)” or
“DC (=)”.
Position the current clamp in such a way that the conductor which is to
be tested runs centrally and at a right angle through the clamp (do not
apply at a slant as this will falsify the measured value). Only ever lead
one conductor through the current clamp!
