Designed for commercial technicians and electricians for the repair & maintenance of electronic appliances, a digital multimeter is an ideal piece of equipment for precise measurement of different electrical parameters.
Digital multimeters have a compact, lightweight, and robust design. They provide easy measurement of electrical parameters including alternating and direct current and safe non-contact voltage detection. Digital Multimeters are fast, reliable, and efficient in measuring 40 + electrical parameters.
Features like an audible alarm or indicator and a flashing backlight make them easy to use even for simple DIY tasks.
Manufactured with a high quality hard, impact resistant, and shock absorbing plastic material and through high quality manufacturing standards, digital multimeters are DM62 drop test certified and have an IP40 rating.
Digital multimeters are most commonly used for the measurement of AC and DC voltage, direct current, decibels, resistance, diodes, and transistors. Digital multimeters give more accurate readings than analog multimeters.
Digital Multimeter comes in various types, and qualities and can be used for a range of voltages, currents, resistance, impedance, and applications. Some digital multimeters have different advanced measuring kits and features that make them expensive compared to simple digital multimeters. The price of a digital multimeter can vary from $50 to $500.
A digital multimeter can serve different purposes and can be used for different applications. So the safety guidelines mentioned here are mostly general so you should also refer to the user manual of your equipment to eliminate any prospective dangers.
A good quality digital multimeter can serve you for years if it is maintained properly. A digital multimeter should always be kept dry. Make sure that the temperature of the surroundings falls within the range of a digital multimeter as extreme temperatures can shorten the life of the meter and can also affect its accuracy.
Generally, a digital multimeter does not require thorough cleaning as they are used in a dry state. But, clean your digital multimeter occasionally with a damp cloth without using any detergent, cleaning agent, or chemicals, and do not immerse it in any liquid. Do not let the water go inside your digital multimeter as it can cause a short circuit.
The battery and fuse of a digital multimeter are consumable parts and need replacement after a certain amount of time.
Along with the quality of its manufacturing, the accuracy of a digital multimeter also depends upon the temperature and relative humidity of the environment where it is being used. The accuracy of a digital multimeter also varies with the variable being measured i.e. current, dc voltage, ac voltage, resistance, capacitance, and frequency. The overall accuracy of a multimeter can vary from ±0.5% to ±10% with the change in the variable being measured.
Digital multimeters are more accurate than analog ones. The maximum possible accuracy with an analog multimeter is ±3% whereas a digital multimeter can reach an accuracy of ±0.5%.
