Give the multimeter a bigger maintenance role.
A multimeter is one of the indispensable tools for an automotive service technician. The early multimeters had very single functions, only simple current, voltage and resistance testing functions, that is, the traditional "A-V-Ω" multimeters. Most of the new multimeters can detect speed, dwell angle, duty cycle, frequency, pressure, time, capacitance, temperature and semiconductor components. With the emergence of multimeters with various brands and functions in the market, people often fall into misunderstandings when purchasing and using this important testing tool, and we will analyze it here.
Multimeter plays a bigger role in maintenance
Misunderstandings in the selection of car multimeters
As a testing tool that is widely used in the maintenance industry, multimeters are required by almost every enterprise. However, the multimeters used by many enterprises may not meet their actual needs.
1. Emphasis on functional diversity while ignoring the matching of accessories
Some users pay more attention to the diversity of multimeter functions when purchasing, but they tend to ignore the matching of accessories. Without the necessary accessories, the diversity of functions cannot be realized naturally. For example, some users hope that the purchased multimeter can detect the starting current and detect the temperature under various conditions, but they do not purchase special current clamps and thermometer probes. If you want to give full play to the function of a car multimeter, the matching of some accessories is very critical. Some of these accessories are necessary, and more are matched with the corresponding functions of the car multimeter.
The accessories in the car multimeter usually include the following types: inductive pick-up, battery alligator clip, special test clip for SMD patch components (used to test parameters such as SMD resistance, capacitance, inductance and transistors, which can be operated with one hand, making Measurement is more convenient), current sensors, pressure probes, torque probes and IC probes, etc. These accessories are generally less used in maintenance. For maintenance companies, when purchasing accessories, they should consider several aspects such as the user's technical quality, the maintenance company's financial status, and daily use, so as to make an appropriate choice in order to achieve the maximum utilization of the equipment.
2. Give up good equipment because of simple language barriers
Some users want to buy imported car multimeters, but after finding out that the interface language is English, they easily give up products with more complete functions or products. In fact, there is no need to do so. The basic functions of various multimeters are similar, and many functions are marked with common symbols, so it is not complicated to use. As long as you go through a simple study, you can quickly master the method of use.
