5-3 Resistance Measurement (Ω)
WARNING
Never apply voltage to the input terminal.
1)
Application: Resistance of resistors and circuits are measured.
2) Measuring ranges:400Ω〜40MΩ(6 range)
3) Measurement procedure
① Set the function switch at
Ω/ / / function.
② Apply the black red test
pin to measured circuit.
③ Read the value on the
display.
④ After 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).
● The input terminals release voltage is about 0.4V.
5-4 Testing Diode ( )
WARNING
Never apply voltage to the input terminal.
1) Application: The quality of diodes is tested.
2) Measurement procedure
① Set the function switch
at Ω/ / / function
and select the function
by SELECT switch.
② Apply the black test pin to
the cathode of the diode and
the red test pin to the anode.
③ Make sure that the display
shows a diode forward voltage drop.
