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. Connecting the red leads (Test leads) to Terminal Input-HI and HI Sense and

black leads to Terminal Input-LO and LO Sense as shown in Figure2-20. That is

connecting the Test leads to both side of the measured resistance.

Figure 2-20 Sketch map for connecting

2. Press twice to switch to 4-Wire Resistance Mode.

3. Choose an appropriate resistance range according to its scope.
