NOTE
You are suggested to make use of Relative function when measuring
small resistance to reduce or escape impedance error from Test leads.
4-Wire Resistance Measurement
When the measured resistance is smaller than 100kΩ, if both the resistance of Test
leads and the contact resistance between probe and testing point are too big to be
ignored as comparing with measured resistance, the error will be increased
provided that you insist on measuring by via 2-Wire Resistance. So please change it
to 4-Wire.
Operating Steps:
1. Press
twice to switch to 4-Wire Resistance Mode.
Figure 2-20 Measurement Interface
2. Connect the red leads to terminal Input-HI and HI Sense and black leads to
terminal Input-LO and LO Sense as the figure below.
