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 intermittent acoustic signal warns of current greater than 10 A. A 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 placing the instrument back into service!
• Be absolutely certain that the measuring ranges are not overloaded beyond their allowable capacities.
Direct and Pulsating Current Measurement, Direct Connection, A DC and A (DC+AC) :
1.
First disconnect supply power from the measuring circuit or the power consumer (1), and discharge any capacitors
2.
In accordance with the current to be measured, turn the rotary switch to A= or A~=
3.
Select the current type appropriate for the measured quantity by briefly pressing the FUNC | ENTER multifunction key.
Each time the key is pressed, the instrument is switched back and forth between A DC and A (DC + AC) TRMS, which is
indicated by means of an acoustic signal. The current type is indicated at the LCD by means of the DC or the
(DC+AC)TRMS symbol
4.
Safely connect the measuring instrument (without contact resistance) in series to the power consumer (2) as shown
5.
Switch supply power to the measuring circuit back on (3)
6.
Read the display. Make a note of the measured value if the instrument is not being operated in the memory mode or the
transmission mode
7.
Disconnect supply power from the measuring circuit or the power consumer (1) once again, and discharge any
capacitors
8.
Remove the test probes from the measuring point and return the measuring circuit to its normal condition
