5-3 Resistance Measurement (Ω)
Never apply voltage to the input terminals.
1) Application
Resistance of resistors and circuits are measured.
2) Measuring ranges
320Ω〜30MΩ (6 range)
3) Measurement procedure
(See fig7, page11)
①Connect the black plug of the test lead to the COM input
terminal and the red plug to the "Ω" input terminal.
②Set the function switch at "Ω" function.
③Apply the black and red test pin to measured circuit.
④Read the value on the display.
⑤After measurement, remove the red and black test pins from
the circuit measured.
●If measurement is likely to be influenced by noise, shield the
object to measure with negative potential (test lead black) .
●If a test pin is touched by a finger during measurement,
measurement will be influenced by the resistance in the human
body to result in measurement error.
●The input terminals release voltage is about 1.3V.
5-4 Checking Continuity (●)
WARNING
Never apply voltage to the input terminals.
WARNING
1) Application
Checking the continuity of wiring and selecting wires.
2) How to use
(See fig8, page12)
①Connect the test lead of the black plug to the COM input
terminal and the red plug to the "● " input terminal.
②Set the function switch at "● /● " function.
③Apply the red and black test pins to a circuit or conductor to
measure.
④The continuity can be judged by whether the buzzer sounds
or not.
⑤After measurement, release the red and black test pinsfrom
the object measured.
