Resistance and continuity
If the resistance is less than 300
Ω
, the instrument is in
continuity.
SCAN
Below 30
Ω
, it emits a continuous beep.
Between 300
Ω
and 3 M
Ω
, the instrument is in resistance
mode. Above 3 M
Ω
, the display unit indicates OL. The 30 M
Ω
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. NON-CONTACT VOLTAGE DETECTION
(NCV)
The instrument can detect an AC voltage of approximately
230V.
Withdraw the probe tips.
Set the switch to
NCV
.
Move the top of the instrument (
+
terminal side) close
to the conductor without touching it. The position of the
instrument may affect the result. The sensitivity is better
on the battery compartment cap side.

COM
Select
If no alternating voltage is detected, the device displays
EF
.
If a voltage is detected, the device displays one of 4 detec-
tion levels:
- , the buzzer beeps once a second and the backlighting
flashes at the same rate.
- - , the buzzer beeps twice a second and the backlighting
flashes at the same rate.
