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.
• 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.
• 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 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.
Direct Current Measurement – CLIP Parameter = OFF
➭ Set the CL iP parameter to 0FF in the current clip setup menu. 
Otherwise all displayed measured values are corrected by the 
amount resulting from the selected transformation ratio for an 
interconnected clip-on current sensor.
