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.
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-sections and lay out connections such that they do not
overheat.
cross-sections and lay out connections such that they do not
overheat.
• An continuous acoustic signal warns of current greater than
11 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.

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.
generated at the same time.
• If a fuse should blow, eliminate the cause of overload before
placing the instrument back into service!
• Fuse replacement is described in section 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 Functions and Measuring Ranges” in the “Over-
load Capacity” column.
