∞
First disconnect power supply 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 acknowl-
edged with an acoustic signal.
∞
Safely connect the measuring instrument (without contact resist-
ance) in series to the power consumer as shown.
∞
Switch power supply to the measuring circuit back on (3).
