5.7 Current Measurement
Notes Regarding Current Measurement
• The multimeter may only be operated with installed batteries
or rechargeable batteries. Dangerous currents are otherwise
not indicated, and the instrument may be damaged.
• Set up the measuring circuit in a mechanically secure fashion, and
secure it against inadvertent breaks. Select conductor cross-sec-
tions and lay out connections such that they do not overheat.
• An intermittent acoustic signal warns of current greater than 10 A.
An continuous acoustic signal warns of current greater than 16 A.
• The input for the current measuring range is equipped with a fuse
link. Maximum permissible voltage for the measuring circuit (=
rated voltage of the fuse) is 1000 V AC/DC.
Use specified fuses only! The fuse must have a
breaking
capacity of at least 30 kA .
• If the fuse for the active current measuring range blows, “FUSE ”
appears at the digital display, and an acoustic signal is generated at
the same time.
• If a fuse should blow, eliminate the cause of overload before plac-
ing the instrument back into service!
• Fuse replacement is described in chapter 9.3.
• Be absolutely certain that the measuring ranges are not overloaded
beyond their allowable capacities. Limit values are included in
chapter 8, “Technical Data”, in the table entitled “Measuring Func-
tions and Measuring Ranges” in the “Overload Capacity” column.
