6. CONTINUITY TEST
WARNING:
NEVER CONNECT THE TEST LEADS TO ANY VOLTAGE WHEN THE FUNC-
TION SWITCH IS SET TO
/
. REMOVE ALL POWER FROM THE CIRCUIT BEING TESTED
WHEN CHECKING RESISTANCE. DISCHARGE ANY CHARGED CAPACITORS.
➔
Set the function switch to
/
.
➔
and appear on the display and the LED
next to V/ / / jack turns on.
➔
Plug the red test lead into the
V/ / / jack and the black test
lead into the
jack.
➔
Apply the test leads to the circuit.
➔
The buzzer will sound if the
resistance is less than 20 and
the measured resistance value will
be displayed in ohms with proper
decimal point.
7. DIODE TEST
WARNING:
NEVER CONNECT THE TEST LEAD TO ANY VOLTAGE WHEN THE FUNCTION
SWITCH IS SET TO / . REMOVE ALL POWER FROM THE CIRCUIT BEING TESTED WHEN
PERFORMING THE DIODE TEST. DISCHARGE ANY CHARGED CAPACITORS.
Note: If the diode is part of a circuit, it is necessary to discon-
nect one end of the diode to avoid any unwanted interference
from the rest of the circuit. The value indicated in the display
during the diode check is the forward bias voltage.
➔
Set the function switch to
/

and appear on the display
and the LED next to V/ / /
jack turns on.
➔
Press

Plug the red test lead into the
V/ / / jack and the black test
lead into the
jack.
