Measuring
testo 382
The measuring range selection switch must
be at the required function before the test
prods are connected to the object being
measured.
Remove the measuring leads from the
object being tested before switching to a
new function or a different measuring range.
The instrument should only be used in a dry
and clean atmosphere. Dirt and moisture
reduce insulation resistances and could lead
to electric shocks in the case of high volta-
ges.
The instrument should only be used in the
measuring ranges specified.
Check if the instrument is working properly
before use (e.g. on a known current or vol-
tage source, see also DIN VDE 0105, Part
1).
Ensure that the measuring leads are in per-
fect order.
The use of makeshift fuses, in particular the
short-circuiting of fuse-carriers is not per-
mitted and may cause the measuring instru-
ment to be destroyed and cause serious
physical injury.
Auto Off - Function
The instrument switches off automatically
after 15 min if not used. A buzzer sounds.
Switch on the instrument again via the "Data
hold / Reset" button.
Voltage measurement
Maximum 1000V AC/DC should be
applied to the input sockets. The
instrument could be damaged and
the user is endangered if these limit values
are exceeded.
Remove the test prods from the object
being measured before selecting a
different measuring range.
1. Set measuring range selection switch to
direct or alternating current (depending
on the type of voltage being measured).
2. Plug the red measuring lead in the
"VΩmA" socket and the black measuring
lead in the "COM" socket.
3. Connect the test prods to the object
being measured. The reading is shown
on the digital display.
Current measurement
Never measure current in circuits
where there are voltages of more
than 250V. Only currents with max.
300mA can be measured in the "VΩmA"
socket and max. 10A in the "10A" socket.
Measuring direct current:
Set the measuring range selection switch to
"µA" or "mA". If the currents are unknown,
always start the measurement in the highest
measuring range and switch to the lower
respective measuring range to achieve the
highest resolution.
