➔ 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.
