3. Choose a proper resistance range according to the scope.
Table 2- 5 Measurement Characteristics of 2-Wire Resistance
Ranges*
200μA、2mA、20mA、200mA、2A、10A
Open-circuit Voltage <8V
Input Protection 1000V on every range (HI terminal)
Configurable
Range, Rel
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.
