The need for a digital multimeter is experienced by specialists in power and low-current networks and masters, whose professional activity is connected with electronics. But not only they demand measuring device. In some cases, it will help you find the cause of the failure of the appliance. Motorists, using the device, will be able to find out the cause of the fault in the wiring of the machine. The device is based on a double-integrated analog-to-digital converter, in which the input signal is compared with the reference signal, the polarity and indication of the overload are determined automatically. Which multimeter to choose, so that it does not fail at the wrong moment, was easy to use, but not overpay for an unnecessary set of functions?

Multimeter which company choose
Most of the models on the market have high-quality stuffing. But the build quality is far from the strength of many measuring devices. A large number of gaps in the case, loose fitting parts affect the life of the device and the accuracy of its readings.
A device of decent quality, which will last more than one year, can be obtained only from a well-established manufacturer in the market.
We recommend that you familiarize yourself with the list of the most popular electronic multimeter brands in Russia, formed in order of decreasing interest in the brand:
1. Mastech
2. Fluke
3. CEM
4. APPA
5. Resanta
6. Elitech
Best low budget multimeters
Even budget digital multimeters have advantages over mechanical measuring devices - they do not need recalculation of readings, but immediately display the result of measurements on the display.
In addition, they have a greater sensitivity to minor changes in current, therefore, give more accurate readings. Budget measuring devices do not have a wide range of functions. They are designed to determine current parameters and help diagnose the integrity of connections.

Which multimeter to buy
The main criteria for choosing a measuring device are the tasks to be performed with its help, and the price group.
1. For domestic use and one-time readings, you can purchase low-budget appliances from Resant or Elitech trademarks. The functionality of Resant DT 830B and Elitech MM 100 multimeters is enough to measure battery charge, remove mains voltage and determine wiring integrity.
2. Specialists who use a multimeter in their professional activities can purchase models with basic functions that are sufficient for taking the required readings: CEM DT-912 and Mastech MAS838. These same devices will be conveniently used by motorists for testing automotive wiring - the enclosures of devices have additional protection, and the quality of the wires allows their use in conditions of an unheated garage.
3. Devices with advanced features can be purchased by professionals who must have a wide range of data to perform their professional activities. If the additional features are not supposed to be used in practice, it makes no sense to overpay for the device.
4. Professional models are necessary when servicing electrical installations where high accuracy of readings is important. Specialists in repair shops and laboratories who diagnose electronic devices and service industrial equipment use professional-grade devices. They should pay attention to the Fluke 17B and APPA 107N models.
