5.8.2 Alternating Current and Frequency Measurement, 

Direct Connection, A AC and Hz

➭ First disconnect supply power from the measuring circuit or 

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

➭ In accordance with the current or frequency to be measured, 

turn the rotary switch to A~ or Hz.

➭ Select the desired measured quantity by briefly pressing the 

FUNC | ENTER multifunction key. Each time the key is 
pressed, AC

TRMS

 and Hz are alternately selected, and 

switching is acknowledged with an acoustic signal.

➭ Safely connect the measuring instrument (without contact 

resistance) in series to the power consumer 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 

power consumer (1) once again, and discharge any 
capacitors.

➭ Remove the test probes from the measuring point and return 

the measuring circuit to its normal condition.
