2-Wire Ohms Verification
Connect the Meter to the test equipment as shown in Figure 3-4 and, depending on which
meter you are calibrating, apply the resistance listed in Table 3-9 or Table 3-10.
Verification forms can be found in Appendix A which can be copied and used to record
each meter reading.
Note
For zero (0) ohms tests, use the 4-wire short to short the Hi/Lo and Sense
