4.4.1 DC and AC Currents up to 1 A (Direct Connection)
➭
Disconnect the
power supply to the
measuring circuit
and/or power con-
sumer (R
V
), and dis-
charge all
capacitors, if avail-
able.
➭
Set the range switch
to position
1/10 A or
1/10 A~.
➭
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!
➭
Set switch to position „ON“.
➭
Reconnect the power supply to the measuring circuit.
➭
Work down to lower current measuring ranges until optimum indica-
tion is obtained. Switching over does not interrupt the measuring
circuit.
➭
Read the measured value on the V, A scale.
