5.8.1 Direct and Pulsating Current Measurement, Direct Connection, 

A DC and A (DC+AC)

➭ First disconnect supply power from the measuring circuit or 

the power consumer (1), and discharge any capacitors.

➭ In accordance with the current to be measured, set the rotary 

switch to A   or A

 

.

➭ Select the type of current 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.

➭ Safely connect the measuring instrument (without contact 

resistance) in series to the power consumer (2) as shown.

➭ Switch supply power to the measuring circuit back on (3).
➭ 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.

➭ Disconnect supply power from the measuring circuit or the
