Measuring low-resistance
1 Press Shift > Lo Ω to make 4- wire low- resistance measurements. (The
Lo Ω annunciator is shown on the display.)
2 Connect the first red and black test leads to output terminals
(FORCE +) and (FORCE –) respectively as shown in Figure 2-4.
3 Connect the second red and black test leads to input terminals
(SENSE +) and LO (SENSE –) respectively as shown in Figure 2- 4.
4 Probe the test points and read the display.
