1. Description

The ESCOLA 30 is an electronic meter with a mir-

rored dial for measurements of current and volt-

age involving analogue techniques for schools

and training use.

The meter allows measurements of AC and DC

current and voltage values and the zero point can

be set up in the centre of the scale for measure-

ment of DC quantities. AC quantities with frequen-

cies of up to 40 kHz can be measured. All the pos-

sible measuring ranges can be selected by means

of a single rotary switch.

The excess current protection of the Escola 30 au-

tomatically limits the power when overloaded. Af-

ter a brief cooling phase, the multimeter au-toma-

tically switches on again.

1 Connection sockets

2 Display with mirror scale

3 Slotted screw for zero calibration

4 Calibration trimmer for setting centre zero point

5 Rotary switch to select the measurement range

6 Three-way switch

The use of a robust moving coil galvanometer and

a mechanically resilient casing make it pos-sible

to use the equipment even under highly challen-

ging conditions. This means that this equipment is

suitable for use in schools by children of all years.

2. Initial calibration



Set up the ESCOLA 30 meter either horizon-

tally or vertically.



Do not connect measuring leads to begin with.



Set the three-way switch to

The needle will point to the zero point of the dial.

If it does not, the amount of charge of the battery

should be checked.
