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-sections and lay out connections such that they do not

overheat.

• A continuous acoustic signal warns of current greater than 1.2 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 600 V AC/DC.

Use specified fuses only! The fuse must have a breaking

capacity of at least 10 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

placing the instrument back into service!

• Fuse replacement is described in chapter 10.3.

• Be absolutely certain that the measuring ranges are not

overloaded beyond their allowable capacities. Limit values are

included in chapter 9, “Technical Data”, in the table entitled

“Measuring Functions and Measuring Ranges” in the

“Overload Capacity” column.
