To Measure Resistance
In view of Resistance measurement function, the following part demonstrated how
to link the measurement connection and how to choose measurement functions. The
following practice will gradually guide you to be familiar with the Resistance
measurement technique. Resistance measurement methods include 2-Wire
Resistances Measurement and 4-Wire Resistances Measurement, we will
perform to explain separately.
2-Wire Resistance Measurement

Basic measurement:
1. Connect test leads as Figure 1-20 shown. Red test lead connects the HI Terminal,
Black test lead connects the LO Terminal.
2. Press to select the 2-Wire Resistance Measurement
3. According to the resistance measuring scope, choose the correct range.
4. Set the Null value
Null computing will be an option operation, could be setup in accordance with
