3. Choose a proper resistance range according to the scope.
Table 2-5 Measurement Characteristics of 2-Wire Resistance
200μA , 2mA , 20mA , 200mA , 2A , 10A
NOTE*:
All the ranges enable to obtain 20% value higher than original. Besides, both Manual and Auto
are available for setting every range.
4. Set relative value (Optional operation).
Press [Rel] to open or close Relative math function. When it is opened, the reading displayed is
a relative value which comes from the result of actual measurement value subtracts the value
that has been set. (Please refer to “ Math Functions” in Chapter 2 to know about the details.)
5. Read measurement result.
Select required measurement rate (reading rate) by pressing [Speed] and read the measurement
result.
6. View history data.
There are four types of way to view historical data: “Number”, “Bar Meter” “Trend Chart” and
“Histogram”.
NOTE:
You are suggested to make use of Relative function when measuring small resistance to reduce or
escape impedance error from Test leads.
