3.4.3 Two and four-wire resistance
2-wire resistance measurements
The Model 2001 can make 2-wire resistance measurements
between 1µ and 1.05G. Assuming “bench reset”
conditions (see paragraph 3.12.1), the basic procedure is as
follows:
1. Connect test leads to the INPUT HI and LO terminals of
the Model 2001. Either the front or rear inputs can be
used; place the INPUTS button in the appropriate
position.
2. Select the 2 function.
3. Select a range consistent with the expected resistance.
For automatic range selection, press the AUTO key. The
AUTO annunciator denotes whether auto-ranging is
enabled.
4. Enable offset compensation if needed (refer to the
procedure later in this paragraph).
Whether or not offset compensation is be-
ing used, the 20, 200, 2k, 20k, and
200k ranges require zero correction in
order to achieve the best accuracy. The
zero correction procedure is located in a
following paragraph.
5. Connect the test leads to the resistance as shown in
Figure 3-14.
