4. Description
The Escola 10 multimeter enables precision
measurements by analogue means in education,
training and practical applications. It measures
AC and DC voltage or current and provides for
measurements with the needle centred on the
dial for DC quantities. Resistance (R) and con-
ductance (G) or impedance (Z) and admittance
(Y) can be obtained by division.
All measurement ranges are selected by means of
the measurement range dial. Two linearised mirror
scales, graded in a 1:3 ratio, guarantee easy read-
ability of the measured values.
The equipment is turned on by means of the
operating mode switch, which is also used to
select between AC, DC or centre zero-point.
The trimmer for setting the zero point in the
centre allows the zero point to be set precisely
when it drifts electrically.
Isolation of the sockets for voltage and current
measurement allow both to be measured in
succession simply by turning the range selector
switch, without any need for reconnecting or
changing the measuring leads.
Use of a robust core-magnet measuring instrument
set-up and an impact resistant casing allows the
instrument to withstand rough handling in awkward
conditions.
The Escola 10 is protected in such a way that
overloads in the selectable current ranges
automatically cause the power to be limited.
5. Operation
•
Switch the multimeter on by select the de-
sired operating mode,
,
or
.
•
To turn off the multimeter, set the mode
switch to the off position
.
•
To test the battery, disconnect all leads from
the multimeter, set the operating mode
switch to
and the measuring range
switch to
. In the
range, the
needle should deflect all the way to the end.
If this is not the case, the battery must be
replaced immediately.
