-64 adapters. Why? AHED adapters map T1 and T2 points
in a uniform alternating pattern: pin 1=T1, pin 2=T2, pin 3=T2, pin 4=T1, etc.

Finding T1 and T2 Points
Why find T1 and T2 points? For a 4-wire measurement, each 4-wire pair must be wired to
one Type1 point and one Type2 point. The location of these T1 and T2 points on the adapter
pins is determined by internal wiring. You can use the probe to find T1 and T2 points. This is
especially useful if the pattern is irregular. To locate the T1 and T2 points, follow these steps:
1. Install the adapters you intend to use for
your 4-wire measurement.
2. From the Main Menu, select Set Up Test
Program.
3. Select Create New Test.
