FUNCTIONS AND FEATURES
3-1. INTRODUCTION
This section provides information about the functions and features of the HP 4278A 1kHz/
1MHz Capacitance Meter. Read Section 2 before reading this section. Information unique
to the Option Interfaces is described in Section 4.
3-2. MEASUREMENT FUNCTIONS
The HP 4278A's measurement functions are classified by frequency into 1kHz, 1MHz nor-
mal, and 1 MHz high accuracy measurement modes.
3-2-1. 1kHz MEASUREMENTS
The 4278A's 1kHz measurement function has seven measurement ranges -- 100pF, 1 riF,
1OnF, 100nF, 14F, 104F, and 1004F. Table 3-1 lists the maximum measurement values for
each of the measurement parameters. Table 3-1 also includes information on the data dis-
play format (position of the decimal point and unit). Maximum D and Q values are 9.99999
and 99999.9, respectively, and the display format for D and 0 is fixed for all ranges.
Tab le 3-1. lkHz Measurement Ranges
Leading zeros preceding the one's digit are place holders and will not be dis-
played. Measurement results which are greater than the values listed in the pre-
ceding table may be displayed.
When the number of display digits is set to less than six digits (4 or 5) the remain-
ing digits will not be displayed.
