Who invented the digital multimeter?

Table of Contents

Donald Macadie
In 1920, a British Post Office engineer, Donald Macadie, is credited with inventing the very first multimeter. The story goes that he was frustrated that he needed to carry a bunch of different tools when working on telecom lines, so he created one tool that could measure amperes, volts, and ohms.

When was the digital multimeter invented?

The first digital multimeter was manufactured in 1955 by Non Linear Systems.

What are the three types of digital multimeter?

There are two basic types of multimeters: digital multimeters and analog multimeters. All digital multimeters have four basic sections: a display, a dial, buttons, and input jacks. Multimeters are categorized into four groups: CAT I, CAT II, CAT III, and CAT IV.

What are the applications of digital multimeter?

The uses of multimeter include the following.

AC/DC voltage measurement.
AC/DC current measurement.
Resistance & continuity measurement.
To check diode.
Measurement of capacitance.
Measurement of frequency.
To test batteries.
A broken power cable can be determined.

How many types of digital multimeter are there?

Types of Digital Multimeter. Digital types of multimeter are available in three types.

Inventors of the Digital Multimeter: The digital voltmeter was introduced by NLS, a California company in 1955 – the same year Fluke introduced the Differential Voltmeter. Fluke’s first digital voltmeter measured True RMS ac volts only (9500A) and was introduced in the mid-60s (Dick Van Saun.) Fluke’s 8100 and 8300,…

How much does a digital multimeter cost?

Digital meters vary in size and design. The most common is the “hand-held” digital multimeter (DMM). If you study electronics you will start using the DMM almost immediately and they can range in cost from $ 0.97 to $1000s. Here is an article on the first practical digital multimeter, the Fluke 8020A DMM.

When did the first digital voltmeter come out?

The digital voltmeter was introduced by NLS, a California company in 1955 – the same year Fluke introduced the Differential Voltmeter. Fluke’s first digital voltmeter measured True RMS ac volts only (9500A) and was introduced in the mid-60s (Dick Van Saun.)

What does the 87V digital multimeter do?

Fluke’s new industrial Digital Multimeter, the model 87V, adds a thermometer function and the ability to accurately measure frequency and voltage on adjustable-speed motor drives Fluke adds Fluke Connect™ in May.
