1. Safety instructions
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.
• 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
floor must be dry.
• To avoid false readings, which could lead to
possible electric shock or personal injury,
replace the batteries as soon as the low bat-
tery indicator (
+ - ) appears.
• Before the case is opened, the meter has to
be switched off and the leads must be dis-
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.
