Introduction
Introducing the Fluke 45 Dual Display Multimeter
Note
This manual contains information and warnings that must be followed to
ensure safe operation and retain the meter in safe condition.
W Warning
To avoid electric shock or injury, read the "multimeter safety"
sheet preceding Chapter 2 before using the meter.
The Fluke 45 Dual Display Multimeter (also referred to as "the meter") is a 4/2-digit
(30,000 count) meter with a 5-digit (100,000 count) high resolution mode. The meter is
designed for bench-top, field service, and system applications. Complete specifications
are provided in Appendix A.
With the (optional) IEEE-488 computer interface installed, the meter is fully
programmable for use on the IEEE Standard 488.1 interface bus(1987). The meter is also
designed in compliance with supplemental standard IEEE-488.2 (1987).
Some features provided by the meter are:
• A dual, vacuum fluorescent, display that allows two properties of an input signal to
be displayed at the same time. (e.g., ac voltage in one display and frequency in the
other).
• Remote operation via the RS-232 interface (included) or the IEEE-488 interface
(optional).
• True rms ac
• (AC + DC) rms, calculated
• Frequency measurements to greater than 1 MHz
• I µV sensitivity in volts dc
• Decibels with variable reference impedance and audio power measurement
capability.
• A compare mode to determine if a measurement is within, above, or below a
designated range.
