4.4.1 DC and AC Currents up to 1 A (Direct Connection)
Ð Disconnect the 
power supply to the 
measuring circuit 
and/or power con-
sumer (R
V
), and dis-
charge all 
capacitors, if avail-
able. 
Ð Set the range switch 
to position
1/10 A  or 
1/10 A~.
Ð Interrupt the mea-
suring circuit and 
safely connect the 
measuring leads 
(without transient resistor!) in series with the power consumer R
v
 . 
With DC current note the polarity!
Ð Set switch to position „ON“.
Ð Reconnect the power supply to the measuring circuit.
Ð Work down to lower current measuring ranges until optimum indica-
tion is obtained. Switching over does not interrupt the measuring 
circuit.
Ð Read the measured value on the V, A scale.
