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
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.
