Example 2: Elimination Leads Impedance
P/F Operation could eliminate impedance errors from leads when measuring
smaller resistance.
Operating Steps:
1. Connecting the red lead (Test leads) to Terminal Input-HI (tested circuit) and
black lead to Terminal Input-LO.
2. Press button, select Resistance (2WR) measurement function.
3. Choose an appropriate resistance range based on the measurement range.
The default is Auto Range.
4. Lead impedance will be shown on the screen as follow after connecting with
two leads together.
Figure 3-2 Lead impedance
5. Set parameters for Relative operation.
(1) Press PRE Current and set the present value as current value.
Figure 3-3 Parameter settings
(2) Press On/Off to open Relative measurement function.
(3) Press continuously and go back to main interface, then you will
obtain final lead impedance.

(4) Besides, The REL on the measurement interface could also open Relative
Operation.
