The Digital Multimeter E conforms to the safety
requirements for electrical equipment for meas-
urement, control and laboratory use in DIN EN
61010 part 1. Safe operation of the apparatus is
guaranteed with correct handling. However,
safety is not guaranteed if the apparatus is han-
dled improperly or carelessly.
Read this manual carefully before using the
digital multimeter and follow the instructions!
Before using the meter, check the case and
test leads for any damage. In the event of
any malfunction/operational defect or visible
damage, do not use the meter. Pay particu-
lar attention to the insulation surrounding the
measurement sockets.
Use with caution when working above 30 V
ACrms, or 60 V DC. Such voltages pose a
shock hazard.
The limit of the measurement range must
not be exceeded. If the values of the meas-
urand are unknown, always switch from a
higher measurement range to a lower one.
When measuring current, turn off circuit
power before connecting the meter in the
circuit.

1. Safety instructions
Connect the common test lead before you
connect the live test lead. When you discon-
nect test leads, disconnect the live test lead
first.
When using the measuring probes, keep
your fingers behind the finger guards on the
probes.
Do not operate the meter around explosive
gas, vapour, or dust.
Do not conduct measurements in a humid
environment. Work area, hands, shoes and

connected from the meter.
Never use the meter when the case is open.
When disposing empty batteries follow the
local regulations. Never dispose of them in
the regular household garbage.
