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.



Set the three-way switch to

Connect the side with the lower potential to

the left-hand socket.

Connect the common/ground lead first and

only then the signal lead.

6.1 DC voltages (V=):
