Current Measurement
Attention!
!
The multimeter should be connected into the line having the
lowest voltage to earth. For safety reasons, the voltage to
earth must not exceed 600 V CAT II or 300 V CAT III!
The measuring circuit must be set up mechanically solid and protected
against accidental opening. The conductor cross sections and the
connection points must be designed in such a way that there will be
no unpermissible warm-up. The current measuring ranges
10 µA ... 1 A are protected by a 1.6 A superquick-action melting fuse
(FF 1.6A/600V AC) in conjunction with power diodes. The maximum
breaking capacity of the protective means is 200 A (one half wave)
with a nominal voltage of 600 V and ohmic load.
Attention!
!
Upon cut-out of the protective means, eliminate the cause of
overload before puting the instrument back to serviceable
condition!
The 10 A range is protected by a 16 A superquick-action melting fuse
(FF 16A/600V AC).
