MEASURING
A. Direct voltage (A V scale)
1. Set knob Sk
2
to position "
".
2. Set knob Sk
1
to position "1200 V" (highest voltage range, to prevent
overloading) and connect the measuring leads to the s and –.
3. Now connect the measuring leads to the voltage source to be measured
and set knob Sk
1
to that measuring position that is most suitable to
provide an accurate reading of the voltage in question.
If the direct voltage in question has a maximum value of .60 mV, knob
Sk2 may be put in position "60 mV
". (Sk
1
may have any position;
the meter protection is cut off!)
B. Direct current (A V scale)
1. Set knob Sk
2
to position "
".
2. Set knob Sk
1
to position "3 A" (highest current range to prevent
damage to the meter due to the selection of too low a range) and
connect the measuring leads to the s and -.
3. Subsequently connect the measuring leads to the current circuit to be
measured and then set knob Sk
1
in that measuring position that is most
suitable to provide an accurate reading of the current in question.
If the direct current has a value of maximum 30 µA, knob Sk
2
may be
put in position "60 mV
". (The position of Sk
1
is unimportant; the
meter protection is cut off!)
C Alternating voltage (A V scale)
1. Set knob Sk
2
to position "~".
2. Set knob Sk
1
to position "1200 V" (highest voltage range to prevent
overloading) and connect the measuring leads to the s and -.
3. Subsequently connect the measuring leads to the voltage source to be
measured and then set knob Sk
1
to that measuring position that is most
suitable to provide an accurate reading of the voltage in question.
