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.
