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:400
Ω〜
40M
Ω
(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.
