Example 2: Elimination Leads Impedance
REL Operation could eliminate impedance errors from leads when measuring
smaller resistance.
Operating Steps:
1. Press button, select Resistance (2WR) measurement function.
2. Connect test leads as Figure 2-18.
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
 REL  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.
