When you buy a multimeter, you get a high-performance, multifunction measuring instrument. This is suitable for use as a voltage and current measuring instrument. As a rule, it can be switched from direct to alternating current parameter measurement, and you can also use it as a resistance measuring instrument. Additional functions are often also possible when it comes to multimeter operation. The measurement parameters are automatically detected and selected via the assignment of the sockets. The function keys are easy to operate and the readings are clearly presented on the display.

Whether you use the multimeter to measure voltage or other measuring values, this instrument is essential in the electronics sector due to its wide range of applications. It
is used both in professional electrical engineering and by do-it-yourselfers.

The advantages of the 760 digital multimeters:

• Automatic detection and selection of measurement parameters via socket assignment
• Easy operation via function keys and large illuminated display
• With true root mean square measurement TRMS

Carry out precise measurements with the innovative digital multimeter

You can use the multimeter to measure current, or also to test voltage and resistance. The level of innovation of the Testo instruments is impressive, thanks to a high standard of reliability and accuracy. You do not need to first select the sockets and then the required measurement function. Instead, the instrument already detects the relevant measurement parameter via the socket assignment. Any possible incorrect settings, which always entail a risk, are thus excluded.

The multimeter operation has a simple structure and it is a sign of how up to date these instruments are. Instead of the usual rotary knob, there are function keys on the handy measuring instrument which can be conveniently operated with one hand. The large, illuminated display makes it easier for you to read out the measured values.

Depending on what model you decide on, the voltage range goes up to 1,000 volts, the frequency range up to 30 MHz and the capacitance up to 60,000 µF. These values apply to the testo 760-3 instrument which is qualified for use in the industrial sector. Here, the multimeter with integrated low-pass filter is for example used for measurements on large electrical systems.

With the professional multimeters, electrical parameters are supplemented by the ability to measure temperatures as well. For this measurement, you attach a thermocouple adapter and the temperature probe, which you can buy separately.

The advantages of the Testo digital multimeters are:

• high operational reliability due to automatic detection,
• exclusion of incorrect settings,
• suitability for a large number of electrical measurement functions,
• large, illuminated display.

The digital multimeter’s measuring tasks

As a useful all-round instrument, a Testo digital multimeter supports you in all electrical measuring tasks. It automatically detects the measurement parameters and provides you with accurate data and improved reliability, regardless of the area of application. Determination of the true root mean square means users are always aware of the exact situation in the electronics area.

Before starting a measurement, users should familiarize themselves with the instrument and check the measuring cables and sockets. You can control the multimeter really easily via the user-friendly, illuminated keys, without needing to use your second hand to help out. The low weight of 340 grams is also an important advantage.

With Testo multimeters, the integrated technology and operational reliability are perfectly attuned to one another:

• numerous instrument functions,
• large measuring range,
• high level of accuracy,
• safety certifications – TÜV; CSA; CE.

Using the multimeter to measure voltage – and carry out other measuring tasks

The measurement of basic electrical parameters becomes child’s play with the multifunction instrument. However, operation may be somewhat more complex, depending on the requirements in terms of electrical measuring tasks.
The comprehensive measuring range enables testing of the current strength up to the μA range. Regardless of the measuring value, the instrument provides extremely accurate results.

Amongst other things, the multifunction instrument is suitable for use as a:

• current and voltage tester,
• resistance measuring instrument,
• capacitance and frequency measuring instrument,
• temperature measuring instrument (an adapter needs to be used for this). Measuring current and voltage with the multimeter

How to measure current with the multimeter

The current strength is measured in amperes and indicates what electrical charge flows through the defined area in a given period of time. Instruments such as the clamp meter are used for the measurement, or the multimeter is employed to measure direct and alternating current.

This is how to proceed when you are measuring current with the multimeter:

• the measuring range is set (start in the high measuring range if the values are unknown),
• the electric circuit is activated and opened,
• the measuring cables are applied and the electric circuit is closed again,
• the ampere value is measured and shown on the multimeter display.
