Example 2: Elimination Leads Resistance Error
When measuring smaller resistance, the test leads resistance may causes large
measurement deviation.
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.
4. In resistance measurement display interface, press Null, start Null function.
