5. Current measurements
The Escola 30 is
not permitted
to be
used for measurements on low-volt-
age mains distribution equipment,
such as mains sockets, circuit breakers
and fuses etc.
The nominal voltage of the electricity
source must not exceed 30 V and its
nominal current must be no higher
than 3 A.
The multimeter is to be connected
in series with the load on the side
where the voltage with respect to
ground is lowest!
Turn off the circuit before the Es-
cola 30 meter is connected into it.
Connect the side with the lower potential to
the left-hand socket.
Connect the common/ground lead first and
only then the signal lead.
5.1 DC currents (mA=):
Set the rotary switch to the desired DC current
range. If measurements are made when the
magnitude of the variable is unknown, always
select a large measuring range before shifting
down to lower ones.
Set the three-way switch to
or, if the
zero point is to be set in the centre, to
.
5.2 AC currents (mA~):
Set the rotary switch to the desired AC current
range. If measurements are made when the
magnitude of the variable is unknown, always
select a large measuring range before shifting
down to lower ones.
Set the three-way switch to
.
