The ESCOLA 100 is an electronic meter with a

mirrored dial for measurements of current and

voltage involving analogue techniques for use in

training, education and work placements.

The meter can handle measurements of current

and voltage values up to 10 A or 600 V and also

allows the zero point to be set up in the centre of

the scale for measurement of DC quantities and

for continuity tests featuring an acoustic signal.

AC quantities with frequencies of up to 40 kHz can

be measured. All the possible measuring ranges

can be selected by means of a single rotary

switch.

The device is protected by a fuse and authorised

for measurements on wiring installations in (CAT

III), e.g. in distribution boxes/consumer units. The

1. Description

current measuring ranges are resistant to long-

term overloading up to 10 A. Generous protection

of all the current ranges by means of semiconduc-

tor circuit breakers prevents the fuse blowing un-

intentionally in many cases.

Switching between measuring ranges does not

break any circuits connected to the equipment.

This means it is possible to carry out measure-

ments on voltage converters, for example, without

causing induction surges. Resistance R, conduct-

ance G, impedance Z and admittance Y can easily

be determined as quotients of current and voltage

measurements thanks to the non-interrupting

switch capability without the need to change the

wiring.
