Measuring Continuity.
•
To test for continuity, do the following:
1. Insert the red test clip into the
Ω
terminal and the black test clip into the
COM terminal.
2. Set the range selector to
.
•
Connect the test clips across with the
object being measured.
•
The beeper sounds continuously when
the resistance value of the tested
circuit ≤10
Ω
.
•
The beeper may not sound when the
resistance value of the test circuit
>100
Ω.
•
The meter displays the value of the test
resistance.
OPERATION
Measuring Resistance.
•
To measure voltage, do the following:
1. Insert the red test clip into the
Ω
terminal and the black test clip into COM
terminal.
2. Set the range selector to
Ω

The resistance ranges are 20

, 20M
Ω
and 2000M
Ω.
•
Connect the test clips across the object
being measured.
•
The measured value shows on the display.
Note:
When measuring at 20
Ω
and 200
Ω
range, the test clips can add 0.1 to 0.3
Ω
error to
resistance.
To obtain precise readings in these low-
resistance measurement, short circuit the input
terminals beforehand and record the reading
obtained and subtract this from the measured
reading displayed.
•
The meter displays “1” when there is no input, for example, open circuit situation.
•
For high resistance measurement (>1M
Ω
), it is normal to take several seconds to
obtain a stable reading.
•
When resistance measurement has been completed, disconnect the connection
between the test clips and the circuit under test and remove the test clips from the
input terminals of the meter.
