Note:
When entering 50
Ω
range, Auto Lead Resistance Calibration
feature activate. See 4-7.
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 and
result in measurement error.
Release voltage of the input terminals is about <1.3VDC.
(<3VDC for 50
Ω
& 500
Ω
ranges)
5-5-3 Resistance Measurement
1) Applications
Resistance of resistors and circuits is measured.
2) Measuring ranges
7 ranges from 50.00
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 to '
Ω
/
' and select '
Ω
' by pressing
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.
