DIYers prefer devices that combine several metrological functions. These include multimeters - devices that allow you to determine the characteristics of an electrical circuit (resistance, current and voltage). All these functions are specified in the instruction manual DT 830B - an inexpensive instrument that measures with a high level of accuracy.

Instrument information
The multifunctional tester is available in use, universal. The model is suitable for work at home, but it has all the features of a professional tool. The set of the device includes measuring probes, a tool for self-diagnosis and a large scale of indicators. The multimeter receives power from a special 9 W power source. The manufacturer has provided only one battery in the set.
The device outwardly resembles standard testers, but has several significant differences. The data is presented in digital form, and the device itself can operate with several parameters. All internal elements are enclosed in a robust housing. The central place on the surface is the switch.
The main advantages of the multimeter:- performance;
- portability;
- ergonomics.
The device is easy to operate thanks to the massive handle with twenty positions. Around it are designations of types of work, which is useful for inexperienced users. The digital liquid crystal screen displays data about the parameter that is being measured.
Technical features
Household electric current meters have a fairly wide range of functions, but professional devices are more accurate and durable. The instructions for use of the DT 830 V multimeter indicate that the device has increased sensitivity. It shows accurate data, but is slightly inferior to more expensive models. Specifications:
-
weight - 135 g; - dimensions - 1, 25x2, 8x7 cm;
- the degree of digit capacity of the liquid crystal display - 3, 5;
- permissible temperature for stable operation - from 0 to 40 degrees;
- alternating voltage - 200-750 V;
- force measurement limit - 200 kOhm;
- constant electric current - 10 A;
- constant voltage - 1 kV.
Professional devices have wider functionality. Many craftsmen lack the verification option. But among the positive differences, an expanded scale of measurements, alarm indicators and diode testers are distinguished.
Operating conditions
For the probes that are included in the kit, there are special openings on the body. Metal rods with insulated handles are required for contact between the conductor and the instrument. The probe is inserted into one of the three slots, each is responsible for a certain indicator. One opening can be negative, common or grounded. It depends on the mode the master chooses to operate the DT 830B multimeter. Detailed instructions make it possible to correctly configure the rest of the sockets.
The second VQmA hole can be used to measure voltage and resistance. If the current exceeds 200 A, then it is necessary to immerse the probe in the third socket marked 10 ADC. As soon as contact is established between the metal rod and the element, information about the parameter will appear on the screen.
Modes and maintenance
Around the switch, the housing is divided into sections that determine the mode of use of the device. Sometimes sectors allow you to accurately indicate measurement fluctuations. The device can operate in two modes - DCV and DCA. The first makes it possible to measure the voltage of a direct electric current as a voltmeter. DCA activates ammeter mode.
The device has a section for evaluating the functionality of the diodes. To do this, you need to insert the probes into the second and third sockets; resistance is measured with their tips. If in the forward and backward directions the indicator is the same, then the element is faulty.
The manufacturer guarantees a long service life of the multimeter, but this is also influenced by the frequency of preventive maintenance. After each use, the device must be cleaned of dust and dirt. To use the DT 830B multimeter for a long time, it is necessary to diagnose it. Do not use the device in high humidity conditions, since the accuracy of the obtained parameters decreases, some elements may be damaged.
The multimeter can be transported on any vehicle, protecting it from extreme temperatures, moisture, mechanical damage and voltage surges. The device should be stored in a well-ventilated room at temperatures up to 40 degrees. It is necessary to protect it from the effects of frost., contact with alkalis, dust, acids, as it all causes corrosion.
The device is suitable for home use. This is the best option for training beginner electricians. It meets the parameters of the electrical network and household appliances. If the case or internal parts are damaged, you need to contact a specialist; you can disassemble the multimeter yourself only if you have experience with such devices.
