Do these steps as follow:
1. To measure an Resistance. Connect test leads as shown below:
Figure 3- 3 Measure Resistance
2. Press button, select Resistance (2WR) measurement function. Choose an
appropriate measurement range.
3. Set the Null measurement function parameters.
(1). Short circuit the test leads.
(2). Press Null Current to set the Null setting value with current
reading.
(3). Press save this setting.
(4). Press to finish the setting and back to a higher level menu.
4. In resistance measurement display interface, press Null, start Null function.
