2.3. RESISTANCE, CONTINUITY, DIODE AND
CAPACITANCE
Connect the red probe tip to the
+
terminal and the black
probe tip to the
COM
terminal.
Set the switch to
W
.
Keep your hands behind the guards of the device and of
the test probe.
Place the test probes on the element to be tested (Figure
12). If a voltage is present, the instrument so indicates.
Do not make a resistance, diode, continuity, or capac-
itance measurement on a live circuit.
As default, the instrument is in automatic mode (
SCAN
) and
chooses automatically among the resistance
, continui-
ty
, diode
, and capacitance
functions. To force
one of these functions, press the
Select
key (the
SCAN
symbol disappears).
Resistance and continuity
If the resistance is less than 300
W
, the instrument is in con-
tinuity (Figure 11). Below 30
W
, it emits a continuous beep.
Between 300
W
and 3 M
W
, the instrument is in resistance
mode. Above 3 M
W
, the display unit indicates OL. The 30 M
W
range is not available in automatic mode; resistance mode
must be used.
Diode
In diode test, place the red probe tip on the anode of the
diode to be tested and the black probe tip on the cathode.
The instrument indicates the voltage of the diode. If it
is above 2V or if the polarity is reversed, the instrument
displays - - - -.
Capacitance
The 3mF and 30mF ranges are not available in automatic
mode; capacitance mode
must be used.
If the device displays
dis.C
after a measurement, wait for
the end of automatic discharging of the capacitance before
making another measurement.
2.4. CURRENT
Connect the current sensor to the
+ terminal
.
Set the switch to
A
.
Press on the yellow opening device to open the flexible
coil (Figure 13).
Open it and place it around the conductor carrying the
current to be measured (Figure 14) (only one conductor
in the sensor).
Close the coil. To optimize measurement quality, centre
the conductor in the coil and make the coil as round as
possible.
The current is displayed.
