A good-to-use multimeter is especially important for an electrician, let's not talk about anything else, just share an interesting little knowledge about the old brand of domestic measuring instruments Unilead digital multimeter, by the way, mention their new generation of ingenuity UT15B MAX UT17B MAX UT18B MAX series of true RMS digital multimeters of those magical functions.
Many people ask what is the function of the "NCV" of a digital multimeter?NCV is actually a function of power verification, if your multimeter strap has "NCV", it is equivalent to saving money for a voltage tester. When you hit this gear, the screen will show "NCV" and two bold "EF", which means that there is no electric field at this time. Once an electric field is detected, the multimeter will send out an audible and visual alarm, and display a horizontal section similar to a dashed line, the stronger the electric field, the more horizontal segments, up to 4 horizontal segments.
Usually, we can use the "NCV" of the multimeter to test a line to see if it has a breakpoint. In addition, there is actually a hidden function here that we can use to distinguish between zero live wires. In an environment with a strong electric field, a single meter pen can be used to distinguish the zero live wire. How does it work?In fact, you can use a watch pen, insert the watch pen into the corresponding jack, and display a horizontal section of the "zero line", and display 4 horizontal sections of the "fire line". How?Do you think there is one more useful knowledge about multimeters?
When it comes to the use of multimeters, the most common concern is actually the problem of accuracy and safety, no, Unilead has launched a new UT15B MAX UT17B MAX UT18B MAX series of true RMS digital multimeters, which perfectly solves these two problems.
First of all, from the point of view of ease of use, this series of multimeters has a large display screen and a backlit digital display, which can clearly see the measurement results even in a dark environmentIt is small in size, and it is also equipped with a magnetic hanging buckle, which is easy to carry and adapt to various measurement environmentsThere is an independent battery compartment on the back, so you don't need to disassemble the rear shell every time you change the battery, which is quite convenientIt is equipped with a support frame, so that even if you dial the gear with one hand, you don't have to worry about not being able to stand up!There is also a 2The 6mm thick protective case comes with two pen slots for easy storage and carrying.
In addition, this series of multimeters also has a convenient one-button wake-up function, which can be easily started by pressing any button;Intimate sound and light alarm for misoperation of the current file, when misoperation, the fuselage will automatically send out the sound and light alarm prompt, so that you can rest assured;There is also a full-post 1000V intelligent anti-burning design, which is safe and secure.
Of course, it's also very reliable when it comes to accuracy. True RMS measurement, measurement of nonlinear waveforms does not need to consider waveform parameters and distortion, and there is no need to worry about error. Coupled with the low-pass filtering VFD function, it can effectively reduce the influence of high-frequency signals on our measurement results, making the measurement accuracy more accurate.
In addition, the UT17B MAX and UT18B MAX two multimeters also have a temperature measurement function, which can easily detect the temperature of the refrigerator and heating plate at home, which is very practical. UT18B Max This multimeter also has an LED intelligent measurement function, jack-type measurement, no need to distinguish between positive and negative polarity, you can directly measure with a watch pen, which is more efficient to use.
When you get your hands on the product, you'll find that there are also two sets of gold-plated watch pens for free!One set of ordinary watch pens and one set of extra tip watch pens are of very good quality and can easily cope with a variety of test scenarios. It's really a watch in hand, and you don't have to worry about measuring!If you are interested in Unilead UT15B MAX UT17B MAX UT18B MAX series multimeter, you may wish to go to its official *** to find out, or you can participate in the experience activity of "Whole Network Evaluation Master" initiated by Unilead, and you can also win a big prize!
