Frequently Asked Questions About Klein MM700 Review

Q. Which is the useful measuring range – manual or auto-range?

A. With inexpensive devices, the measuring range must be set manually before use. There are usually several areas for each measurement type, which sometimes makes the labeling of the central selection controller on the multimeter very confusing.

Good multimeters from the test offer the user a so-called “auto-range” function. That means you will be able to select only the measurement type. A manual setting is usually still possible on request. The auto-range function is particularly practical if you cannot estimate the measuring range to be expected.

In this case, with a cheap multimeter, you have to slowly grope your way. With a good multimeter, you can simply start measuring.

Q. What should a multimeter do?

A. A multimeter is used to determine a wide variety of measurement variables. The functionality of the measuring devices from the Klein MM700 review goes far beyond the basic functions for measuring voltage, current, and resistance (all three sizes of Ohm’s law).

Here is an overview of which functions are most important:

Basic Functions

    • Perfectly measures electrical voltage in volts Determines the voltage of an energy source (e.g. battery).
    • Measure electrical current in amperes Determine the current in a circuit.
    • Easy measure resistance in ohms Determines the resistance of a component or device.

Advanced Functions

    • Continuity tester Check whether current flows through a line or component.
    • Diode tester Check whether diodes are working properly.
    • Measure capacitance Check capacitance of a capacitor.

Additional functions

    • Measure exact temperature in degrees Celsius (° C)
    • Easily measure frequency in the heart (Hz)
    • Measure brightness in lux (lx)
    • Perfect for measure volume in decibels (dB)
    • Measure moisture in percent (%)

Q. What measuring accuracy should the device have?

A. The possible deviation from the actual measurement result is given in some models for individual measuring ranges in the form of a percentage. Depending on the area, the value is usually between 0.5% and 1%. Higher quality multimeters have higher measurement accuracy.

There is no absolute measurement accuracy of 100% in any model since the measurement result is always influenced by various factors.

Q. What is the resolution or multimeter counts all about?

A. The multimeter counts indicate the accuracy of the display resolution, i.e. how many different values ​​can be shown on the display. The higher the value of the counts, the more digits are displayed. With a high number of counts, the device can show even the smallest changes in the measured value for the user on the display.

This makes the measurement result more precise. A device with 2000 counts can, therefore, output measured values ​​in a range from 0 to 1999. The decimal point can be anywhere. A good multimeter generally has a higher resolution than a cheap multimeter.

Q. Which measurement category should the device belong to?

A. The required measurement category is determined by the application. You should always base yourself on the highest category in which the device is to be used. Category III devices are sufficient for most applications. Professional users, on the other hand, use CAT IV multimeters.

Q. Is the True RMS function required?

A. Multimeters with True RMS (True Root Mean Square) function can measure the effective value of AC voltages regardless of the curve shape when measuring non-sinusoidal signals and are therefore designed with more complex circuits and are therefore more expensive to purchase.

True RMS multimeters are therefore mainly used in professional applications. This function is not too relevant for hobbyists. Only the professional devices from our test support this measurement method.

Q. What is the evaluation of the computer data?

A. As a rule, the measured value is read directly from the display. Some models can also save the data in the device itself. If you want to carry out an exact evaluation of your measurement results, you cannot avoid transferring the data to your PC.

Some multimeters are equipped with a special PC interface for this. This has an optocoupler with LED sensors on the multimeter and a USB connection on the PC. The corresponding software is included.

Q. Any special designs of multimeters?

A. The most common models for every application are the simple handheld multimeters.

  • Table multimeters are available for professional use in industry and research.
  • Special small and compact devices are called mini multimeters. Models with an integrated current clamp are referred to as current clamp multimeters.
  • Pen design multimeters are known as pen multimeters.
  • The term automotive multimeter can be used for use in the field of car electronics.
  • If a connection to the computer is possible, individual models are also called USB multimeters.

Simple devices are particularly suitable for quickly checking basic electrical sizes. If you want to deal more intensively with the subject of electrics and electronics, you cannot avoid a good device for professional applications.

But a multimeter should be in every well-stocked toolbox.


All in all, in our Klein MM700 review, we must conclude that this multimeter is one of the best multimeters in the market with great build quality and durability. Also, it is easy to use for both professional and amateur electricians.

It is necessary to mention that some of the most common electrical parameters are voltage, intensity, resistance, and continuity which this device measures accurately. Also, you can use the device to measure temperature, capacitance, continuity, frequency, and operating cycle and test diodes.

One of the best things about Klein MM700 is that it comes with a powerful battery which is very easy to change. Also, its display is crisp and bright. According to our suggestion, you should not think twice to buy this great product which is built to last for many years.
