Measurement Application Examples
4-1 Introduction
Section 4 describes some advanced features and applications that help the
user to operate the meter more effectively. The user must be familiar with the
basic measurement operations described in Section 2 and Section 3 and has a
basic understanding of electronics knowledge.
4-2 Applications for Using Dual Display
The dual display capability is one of the most useful features provided with
the meter. User may take the advantages to greatly enhance the test and
measurement capabilities.
Some common combinations and applications of using dual display are
provided in Table 4-1.
