“OL” (overload) displayed, the
diode has a forward voltage
higher than 2 V (e. g. in case of
LEDs), or it is interrupted, con-
nected in reverse direction
(reverse the polarity of the diode),
or not connected.
5.4 Continuity check
●
However, never perform a conti-
nuity check when voltage is ap-
plied, otherwise the measurement
will be inaccurate.
1) Set the orange sliding switch (5)
to the upper position
.
Press the button
(4) so
many times until the buzzer sym-
bol is
displayed.
2) Apply the test prods to the corre-
sponding measuring points. The
internal buzzer will sound if the
forward resistance is less than
35
Ω
. In addition, the resistance
will be displayed. With “OL” (over-
load) displayed, the value is
higher than 339.9
Ω
.
5.5 Manual range selection
The measuring range for voltage and
resistance measurements is always
automatically selected in an opti-
mum way
unless
the symbol
is
shown on the top right of the display.
1) To hold a measuring range se-
lected automatically, press the
