Note:
To compensate internal and lead resistance for low ohm
measurement, use Relative function.
If measurement is likely to be influenced by noise, shield the
object to measure with negative potential (COM).
If a finger touches a test pin 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 <1.3VDC.

5-5-2 Resistance Measurement
1) Applications
Resistance of resistors and circuits are measured.
2) Measuring ranges
6 ranges from 500.0
Ω
to 50.00M
Ω
.
3) Measurement procedure
Connect the plug of black test lead to COM input terminal
and plug of red test lead to
Ω
input terminal.
Set the function switch at '
Ω
/ ' and select '
Ω
' with the
" SELECT " button.
Apply the red and black test pins to an object to measure.
The reading is shown in the display.
After measurement, release the red and black test pins from
the object measured.
