•

Connect the common test lead before you

connect the live test lead. When you discon-

nect test leads, disconnect the live test lead

first.

•

Before the case is opened, the meter has to

be switched off and the leads must be dis-

connected from the meter.

•

When disposing empty batteries follow the

local regulations. Never dispose of them in

the regular household garbage.

3. 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) aund admittance

(Y) can be obtained by division.

All measurement ranges are selected by means of

a rotary dial. Two linearised mirror scales, graded in

a 1:3 ratio, guarantee easy readability of the meas-

ured values.

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

over-loads in the selectable current ranges

automatically cause the power to be limited.
