Measurement Operation(7)
Warning
To avoid damages to the Meter or to the devices under
test, disconnect circuit power and discharge all the
high-voltage capacitors before measuring continuity.
To test for continuity, connect the Meter as follows:
1. Insert the red test lead into the
V
Ω
terminal and
the black test lead into the
COM
terminal.
2. Set the rotary switch to
Ω
and press
SELECT
button to select measurement mode.
3. The buzzer sounds if the resistance of a circuit under
test is less than 50
Ω .
4. The buzzer may or may not sounds if the resistance
of a circuit under test is between 50
Ω
to 120
Ω .
5. The buzzer does not sound if the resistance of a circuit
under test is higher than 120
Ω.
Note
l
The buzzer beeps once when pressing any buttons
at any rotary switch positions except at 2/20A positions
if the button is valid. If the button is not valid, it does
not beep. At 2/20A rotary switch position, the buzzer
is set not to beep.
l
The buzzer beeps 5 times continuously on around
1 minute before entering the sleep mode. When it
is just before entering the sleep mode, it will have
one long beep to warn you.
l
The LCD displays
OL
indicating the circuit being
tested is open.
l
When continuity testing has been completed, disconnect
the connection between the testing leads and the
circuit under test and remove testing leads from the
input terminals.
