Apply the test leads to the resistor being measured. If the resistor is part
of a circuit, it is necessary to disconnect one end of the resistor to avoid
any unwanted interference from the rest of the circuit.
Read the displayed resistance.
NOTE:
• ‘I’ is also displayed when the inputs are not connected.
• When measuring resistance above 1M
, the meter may take a few seconds to get
a stable reading.
• Never measure a resistor that has voltage on it.
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 / .
The LED next to
V/ /F/ /
jack will turn on.
Plug the red test lead into
V/ /F/ /
jack and
the black test lead into jack.
Apply the test leads to the circuit.
The buzzer will sound if the
resistance is less than 30 and the
measured resistance value will be
displayed in ohms.
