1. Safety instructions/using the equipment safely
The Escola 2 multimeter is designed to display
electrical measurements in the ranges and
measurement environments specified in its tech-
nical data.
It conforms to safety regulations for electrical
measurement, control and laboratory equip-
ment, as specified in DIN EN 61010-1, protec-
tion class 2 and to excess voltage category CAT I
for up to 30 V. It is intended for measurements on
experiments and laboratory apparatus. It is
not
approved for measurements on low-voltage dis-
tribution equipment, such as sockets, fuses, etc.
CAT I: Signal layer, telecommunications, elec-
tronic equipment with only minor excess voltage
transients
CAT II: Domestic appliances, mains sockets,
portable instruments etc.
CAT III: Supply via buried cabling, built-in swit-
ches, automatic circuit breakers, sockets or
contactors
CAT IV: Equipment and installations supplied,
for example, by overhead mains cables and
therefore subject to greater risk of lightning
strikes. This includes, for example, main swit-
ches at the building mains feed, electricity me-
ters and ripple control receivers.
Safe operation of the multimeter is guaranteed if
it is solely used as specified. Safety cannot be
guaranteed, however, if the multimeter is used
incorrectly or handled without due care and at-
tention. In order to avoid serious injury due to
current or voltage shocks, the following safety
instructions are to be observed at all times:
