5.7.1 Direct and Pulsating Current Measurement, Direct Connection, A

DC and A (DC+AC)

Ð First disconnect supply power from the measuring circuit or

the power consumer, and discharge any capacitors.

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

switch to A or A .

Ð Select the type of current appropriate for the measured quan-

tity by briefly pressing the multifunction key FUNC | ENTER. 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.

Ð Safely connect the measuring instrument (without contact re-

sistance) in series to the power consumer as shown.

Ð Switch supply power to the measuring circuit back on.

Ð Read the display. Make a note of the measured value if the in-

strument is not being operated in the memory mode or the

transmission mode.

Ð Disconnect supply power from the measuring circuit or the

power consumer once again, and discharge any capacitors.

Ð Remove the test probes from the measuring point and return

the measuring circuit to its normal condition.

Ð Direct frequency measurement, A (DC + AC)
