4. Operation
4.1 Readying for use
•
Insert battery into the battery compartment.
To do this open the appropriate section of
the housing by pressing in the nub (7), e.g.
using a screwdriver. Then insert the battery
and connected it to the battery clip. Replace
the section of housing and snap it into place.
•
Check the mechanical zero-point. The
measuring instrument may not be connected
to anything at this time. The needle must be
located in the zero-point position when the
multimeter is in a horizontal position. If nec-
essary make the corresponding adjustments
by means of the adjustment screw (6).
•
Check the full scale deflection setting for 0 Ω.
To do this set the rotary switch (1) to "x 1
Ω". Shortcircuit the connection sockets

"COM" (5) and "A, Ω" (4). Set the full scale
deflection by turning the knob (2).
•
If full scale deflection cannot be set or the
needle no longer stays still, the battery must
be replaced.
4.2 General instructions
•
When performing measurements always set
the rotary switch (1) to the highest meas-
urement range. Then turn to lower ranges
until the optimum needle deflection is ob-
tained.
•
When the multimeter is not in use, discon-
nect all measurement leads from the meter,
reset the rotary switch (1) to the highest
range and, if necessary, remove the battery.
4.3 Voltage measurement
4.3.1 DC voltage up to 100 mV
•
Set the rotary switch (1) to the measurement
range "50 μA, 100 mV".
•
Connect the multimeter and take a reading
from the V, A DC scale.
4.3.2 DC voltage up to 600 V
•
Using the rotary switch (1) select the corre-
sponding measurement range "600,...,1 V
DC".
•
Connect the multimeter and take a reading
from the V, A DC scale.
4.3.3 AC voltage up to 600 V
•
Using the rotary switch (1) select the corre-
sponding measurement range "600,...,10 V
AC".
•
Connect the multimeter and take a reading
from the V, A AC scale.
