 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
