Current Measurement
Notes Regarding Current Measurement
•
The multimeter may only be operated with installed rechargeable
battery pack or mains module. 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.
•
In the case of current greater than 1.1 A, “
OL
” appears at the
display.
•
The input for the current measuring range is equipped with a
fuse link. Maximum permissible voltage for the measuring cir-
cuit (= rated voltage of the fuse) is 1000 V AC/DC.
Use specified fuses only! The fuse must have a
breaking capac-
ity of at least 30 kA
.
•
If the fuse for the active measuring range
has blown, the blown fuse symbol appears
at the digital display.
•
If a fuse should blow, eliminate the cause of
overload before placing the instrument back into service!
•
Fuse replacement is described in Chapter 9.3.
•
Be absolutely certain that the measuring ranges are not over-
loaded beyond their allowable capacities. Limit values are
included in chapter 8, “Characteristic Values”, in the table enti-
tled “Measuring Functions and Measuring Ranges” in the
“Overload Capacity” column.
