Example 2: Elimination Test Leads Resistance Error
When measuring smaller resistance the test leads resistance causes the
measurement to have a great deviation. So we need to eliminate errors caused by
resistance test leads.
Do these steps as follow:
1. Connect test leads as Chapter 1 introduced. Now we want to measure an AC
Voltage. Connect test leads as shown:
Figure 3-3
2. Press button, select Resistance measurement function. And choose a
correct range.
3. Set the Null measurement function parameters.
(1). Make the test leads shorted.
(2). Press Æ Null , set the Null setting value with current reading.
(3). Press
save this setting.
(4). Press , finish the setting and back to a higher level menu.
4. In resistance measurement display interface, press Null , start Null function.
5. Lead test leads into circuit, starts to measurement.
