Do these steps as follow:
1. To measure a Resistance. Connect test leads as shown in Figure 1- 19.
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.
