Example 2: To Eliminate Leads Impedance
Relative Operation could eliminate impedance errors from leads when
measuring smaller resistance.
Operating Steps:
1. Press on the front panel to select 2-Wire Resistance measurement
function.
2. Connect the red lead to terminal Input-HI and black lead to terminal
Input-LO as Diagram 2-14.
3. Choose a proper resistance range according to the scope. The default is
Auto Range.
4. Lead impedance will be shown on the screen as follow after connecting
with two leads together.
